Object Disorders of the cervical spine can be successfully addressed by surgical intervention when the choice of such intervention takes into account the possible complications in the treated and adjacent structures. The aim of this study was to investigate the potential for intraoperative trauma in cervical zygapophysial joints and to describe possible pathological changes that may occur during cervical spine surgery. Methods Fifteen sheep underwent surgical intervention via an anterior cervical approach; discectomy at the C5–6 level was performed. In 10 animals, the discectomy was accompanied by titanium cage fusion. The sheep were killed immediately after completion of the operation. Radiological examination of the isolated cervical spines followed. Furthermore, the cervical spines were submitted to decalcification and incised using a microtome, and tissue sections were then studied using light microscopy. Results Radiological examination was used to assess vertebral alignment, vertebral body (VB) morphology, implant position, and endplate and facet joint gross morphology. Histological examination of the endplate and VB demonstrated degenerative lesions as well as cellular necrosis. The study of the facet joints at the treated as well as at adjacent segments (both above and below) revealed in some cases edema between the collagen fibers of the joint capsules, congestion, and microhemorrhages. Injuries were evident in animals in which the Caspar device was used. Conclusions Histopathologically confirmed lesions occurred in facet joints while anterior cervical spine surgery was being performed in sheep. The findings were indicative of trauma and, in the case of human spine surgery, could possibly account for several postoperative complications and patient complaints.

The goal of this study was to quantify the relative contributions of each muscle group surrounding the spine to vertebral joint rotational stiffness (VJRS) during the push-up exercise. Upper-body kinematics, three-dimensional hand forces and lumbar spine postures, and 14 channels (bilaterally from rectus abdominis, external oblique, internal oblique, latissimus dorsi, thoracic erector spinae, lumbar erector spinae, and multifidus) of trunk electromyographic (EMG) activity were collected from 11 males and used as inputs to a biomechanical model that determined the individual contributions of 10 muscle groups surrounding the lumbar spine to VJRS at five lumbar vertebral joints (L1-L2 to L5-S1). On average, the abdominal muscles contributed 64.32 ± 8.50%, 86.55 ± 1.13%, and 83.84 ± 1.95% to VJRS about the flexion/extension, lateral bend, and axial twist axes, respectively. Rectus abdominis contributed 43.16 ± 3.44% to VJRS about the flexion/extension axis at each lumbar joint, and external oblique and internal oblique, respectively contributed 52.61 ± 7.73% and 62.13 ± 8.71% to VJRS about the lateral bend and axial twist axes, respectively, at all lumbar joints with the exception of L5-S1. Owing to changes in moment arm length, the external oblique and internal oblique, respectively contributed 55.89% and 50.01% to VJRS about the axial twist and lateral bend axes at L5-S1. Transversus abdominis, multifidus, and the spine extensors contributed minimally to VJRS during the push-up exercise. The push-up challenges the abdominal musculature to maintain VJRS. The orientation of the abdominal muscles suggests that each muscle primarily controls the rotational stiffness about a single axis.

Objective: The quantification of inter-segmental spine joint reaction forces during common workplace physical demands. Background: Many spine reaction force models have focused on the L5/S1 or L4/L5 joints to quantify the vertebral joint reaction forces. However, the L5/S1 or L4/L5 approach neglects most of the intervertebral joints. Methods: The current study presents a clinically applicable and noninvasive model which calculates the spinal joint reaction forces at six different regions of the spine. Subjects completed four ambulatory activities of daily living: level walking, obstacle crossing, stair ascent, and stair descent. Results: Peak joint spinal reaction forces were compared between tasks and spine regions. Differences existed in the bodyweight normalized vertical joint reaction forces where the walking (8.05[Formula: see text][Formula: see text][Formula: see text]3.19[Formula: see text]N/kg) task had significantly smaller peak reaction forces than the stair descent (12.12[Formula: see text][Formula: see text][Formula: see text]1.32[Formula: see text]N/kg) agreeing with lower extremity data comparing walking and stair descent tasks. Conclusion: This method appears to be effective in estimating the joint reaction forces using a segmental spine model. The results suggesting the main effect of peak reactions forces in the segmental spine can be influenced by task.

Background: Ankylosing spondylitis (AS) may affect peripheral joints, with the shoulder, hip, and knee being well known involved sites. However, involvement of the proximal tibiofibular (PTF) joint has not yet been investigated. Purpose: To evaluate PTF joint abnormalities in patients with AS. Material and Methods: From July 1997 to June 2005, 16 patients (15 male, one female; mean age 25 years), who were clinically diagnosed with AS, underwent magnetic resonance imaging (MRI) to evaluate knee pain. All patients also underwent plain radiographs of the knee, lumbar spine, and pelvis. Twenty knee MRIs (bilateral in four patients) and 16 sets of knee, lumbar spine, and pelvic radiographs were retrospectively reviewed in order to evaluate possible AS involvement. The presence of abnormalities suggesting AS involvement were recorded separately in the sacroiliac joints, lumbar spine, hip, and femorotibial and PTF joints. If the PTF joint showed any pathologic findings, the radiologic findings were recorded. Results: Three of 16 patients (18.7%) had pathologic features of the PTF joint observed by plain radiographs or MRI. One of these three patients showed bilateral involvement of the PTF joints on plain radiographs, while the other two patients showed unilateral involvement on MRI. Subchondral sclerosis, cartilage abnormality, erosion, and abnormal bone marrow signal intensity were identified on MRI. Plain radiographs of two patients revealed subchondral sclerosis and spur formation in the PTF joint. The frequencies of involvement of other joints in the 16 patients were as follows: lumbar spine, n=5 (31%), hip joint, n=1 (6%) (identified by plain radiographs), and femorotibial joints, n=10 (62.5%) (identified by knee MRI). Conclusion: MR imaging of the PTF joint can depict synovial changes and their effect on joint structures in patients with AS. The MRI findings of AS involving the PTF joints are subchondral sclerosis, cartilage abnormality, erosion, and abnormal bone marrow signal intensity.

✓ The thoracic spine is stabilized in the anteroposterior direction by the rib cage and the facet joints. Spondylolisthesis of the thoracic spine is less common than that of the lumbar spine. The authors describe a rare case of thoracic spondylolisthesis in which the patient suffered back pain and myelopathy. The patient was a 44-year-old woman. Plain radiography revealed Grade I T11–12 spondylolisthesis. The pedicle–facet joint angle at T-11 was 118°, greater than that of T-10 or T-12. Postmyelography computerized tomography scanning revealed posterior compression of the dural sac as well as enlargement of and degenerative changes in the facet joint at T-11. Magnetic resonance imaging showed anterior and posterior compression of the spinal cord at the level of the spondylolisthesis. To achieve posterior T10–12 decompression, the surgeons performed a laminectomy and posterolateral fusion in which a pedicle screw fixation system was placed. The patient’s back pain disappeared immediately after the operation. The authors conclude that the enlargement of the pedicle–facet joint angle and the degenerative changes of the facet joint caused the thoracolumbar spondylolisthesis.

ObjectivesThe size and shape of a joint cavity are the key determinates for the mobility of the joint. The anatomy and configuration of the facet joint (FJ) recesses at different levels of the spine remain unclear and controversial. The aim of this study was to identify the configuration of the FJ recesses in the cervical, thoracic and lumbar spine using a combination of micro-CT and sheet plastination techniques.MethodsOf 19 cadavers (9 males, 10 females, age range of 54–89 years), the FJ cavities of 3 spines were injected with contrast filling and scanned with micro-CT, and 16 plastinated spines were prepared as the series of sagittal (9 sets), transverse (5 sets) or coronal (2 sets) sections with a thickness of 2.5 mm and examined under a stereoscopic microscope.ResultsThis study characterised the FJ spaces and recesses of the spine and found that (1) the configuration and extent of the FJ recesses varied along the spine. The optimal needle approach to the FJ cavity was via an anterolateral or posterolateral recess at the cervical level, along the tip of the inferior articular process at the thoracic level and via the posteromedial recess at the lumbar level. (2) The FJ cavity did not communicate with the retrodural space.ConclusionThe anatomical features of the FJ recesses at different levels of the spine confirm no direct communication between the FJ cavity and retrodural space.

The uncovertebral joints appear in the adult human cervical spinal column. While the descriptions of this structure have been reported, methods to quantify the dimensions of these joints are lacking. Therefore, in this study a preliminary attempt was made to develop a methodology to quantify the three-dimensional anatomical details of these joints in the adult human cervical spine using sequential cryomicrotome anatomic sections. Bilateral dorsal to ventral length, medial to lateral depth, and caudal to cranial height measurements were obtained from C2-T1 levels. The well developed larger joints were observed in the mid to lower cervical (C3-C7) regions and the smaller joints were noted in the most cranial and caudal (C2-C3, C7-T1) levels. Uncovertebral joints in the mid to lower cervical region extended further ventrally compared to the most cranial and caudal levels. The height of the uncovertebral joints was equal to the lateral height of the intervertebral discs throughout the extent of the joint. The mean overall medial to lateral depth of the joint was 3.8 mm (± 1.8). These quantitative three-dimensional descriptions assist in describing uncovertebral joints in stress analysis based finite element models to understand its effects on the cervical spine biomechanical behavior.

Object The uncovertebral joints are peculiar but clinically important anatomical structures of the cervical vertebrae. In the aged or degenerative cervical spine, osteophytes arising from an uncovertebral joint can cause cervical radiculopathy, often necessitating decompression surgery. Although these joints are believed to bear some relationship to head rotation, how the uncovertebral joints work during head rotation remains unclear. The purpose of this study is to elucidate 3D motion of the uncovertebral joints during head rotation. Methods Study participants were 10 healthy volunteers who underwent 3D MRI of the cervical spine in 11 positions during head rotation: neutral (0°) and 15° increments to maximal head rotation on each side (left and right). Relative motions of the cervical spine were calculated by automatically superimposing a segmented 3D MR image of the vertebra in the neutral position over images of each position using the volume registration method. The 3D intervertebral motions of all 10 volunteers were standardized, and the 3D motion of uncovertebral joints was visualized on animations using data for the standardized motion. Inferred contact areas of uncovertebral joints were also calculated using a proximity mapping technique. Results The 3D animation of uncovertebral joints during head rotation showed that the joints alternate between contact and separation. Inferred contact areas of uncovertebral joints were situated directly lateral at the middle cervical spine and dorsolateral at the lower cervical spine. With increasing angle of rotation, inferred contact areas increased in the middle cervical spine, whereas areas in the lower cervical spine slightly decreased. Conclusions In this study, the 3D motions of uncovertebral joints during head rotation were depicted precisely for the first time.

Introduction. Restoration of trunk balance is the basic task in surgical correction of spinal deformities and in hip joint instability of various etiology. Purpose. To analyze and to define the relevance of roentgen-anatomical parameters of spine-pelvis relationships for surgical correction of deformities in the thoracolumbar spine and of hip joint instability of dysplastic and neurogenic etiology. Material and methods. An X-ray analysis of parameters of the frontal and sagittal spine-pelvis balance was performed in 220 patients with dysplastic and neurogenic deformities of the thoracic and lumbar spine (n = 98) and with instability of hip joints (n = 122) but who were able to walk. They were operated in the neuro-orthopedic department with orthopedics in National Medical Research Center for Children’s Health. The reference group included 60 relatively healthy children without any scoliotic deformities of the spine and with stable hip joints. Dynamics of changes in X-ray parameters was analyzed using findings of orthostatic spondylograms from the indicated groups of children. The obtained data were compared with reference values. Results. The trial performed has revealed typical changes in spine-pelvis relationship parameters in patients with hip joint instability and spine deformities and in the reference group . The researchers also found out relations between various parameters of the trunk balance before and after surgical correction. Conclusion. While planning a surgical correction of trunk balance in spinal deformities, one should take into account parameters of spine-pelvis relationships, such as PI, SS, PT, SVA deviation and the mid-sacral line; and in case of hip joint instability - local roentgen-angulometric parameters of the femoral and acetabular components of instability. This is due to the fact that the lower the level of reconstructive surgical manipulation is located, the greater effect it has at the frontal and sagittal balance of the trunk.

Lumbar spine fusion (LSF) is a common surgical procedure used in the treatment of lower back pain. Numerous studies have been conducted investigating the effects of LSF. Biomechanical studies have found that mechanical changes at adjacent joints create cumulative stress and pain, while clinical studies suggest that many patients develop symptomatic adjacent segmental disease (ASD) following LSF, which may necessitate additional surgery. Recently, ASD pain following LSF has been attributed to accelerated sacroiliac (SI) joint degeneration. Normal SI joints are mobile segments adjacent to the lumbosacral spine articulation and it has been hypothesized that altered biomechanics at the SI joints due to LSF could accelerate degeneration of the joints. The purpose of this study was to obtain a better understanding of the biomechanics at the SI joints and to determine whether LSF causes biomechanical changes at the SI joints. Six cadaver pelves were tested in flexion/extension, torsion, double leg compression and single leg compression, under four conditions: 1) intact, 2) after a 360 degree instrumented fusion at L4-5, 3) after a 360 degree instrumented lumbosacral fusion at L4-S1 and 4) after a unilateral SI joint fusion. Anterior and posterior SI joint movements were recorded during the study, along with load/displacement data. This study proved that motion does exist at the SI joints, although it is quite variable between specimens and between right and left SI joints within an individual specimen. It was also determined that changes in biomechanics do occur at the SI joints following fusion (L4-5, L4-S1 and unilateral SI joint fusion). Anteriorly, an overall increase in motion was detected at the SI joints during axial compression as fusions were performed. The posterior SI joints also demonstrated increased motion, however, this increase was detected in all of the parameters tested (flexion/extension, torsion and axial compression). However, due to the small number and variability of specimens tested, significance could not be established. The results of this study may help surgeons make more informed decisions, by being made aware of SI joint degeneration as a possible side effect of fusion surgeries, and taking that into consideration when determining a treatment plan.

Facet joint injections and epidural needle insertions are widely used for spine anesthesia. Needle guidance is usually performed by fluoroscopy or palpation, resulting in radiation exposure and multiple needle re-insertions. Several ultrasound (US)-based guidance approaches have been proposed to eliminate such issues.However, but they have not widely accepted in clinics due to difficulties in interpretation of the complex spinal anatomy in US, which leads to clinicians' lack of confidence in relying only on information derived from US for needle guidance. In this thesis, a model-based multi-modal joint registration framework is introduced, where a statistical model of the lumbar spine is concurrently registered to intraprocedure US and easy-to-interpret preprocedure images. The goal is to take advantage of the complementary features visible in US and preprocedure images, namely Computed Topography (CT) and Magnetic Resonance (MR) scans. Two versions of a lumbar spine statistical model are employed: a shape+pose model and a shape+pose+scale model. The underlying assumption is that the shape and size of the spine of a given subject are common amongst all imaging modalities . However, the pose of the spine changes from one modality to another, as the patient's position is different at different image acquisitions. The proposed method has been successfully validated on two datasets: (i) 10 pairs of US and CT scans and (ii) nine US and MR images of the lumbar spine. Using the shape+pose+scale model on the US+CT dataset, mean surface distance error of 2.42 mm for CT and mean Target Registration Error (TRE) of 3.14 mm for US were achieved. As for the US+MR dataset, TRE of 2.62 mm and 4.20 mm for the MR and US images, respectively. Both models models were equally accurate on the US+CT dataset. For US+MR, the shape+pose+scale model outperformed the shape+pose model. The joint registration allows augmentation of important anatomical landmarks in both intraprocedure US and preprocedure domains. Furthermore, observing the patient-specific model in preprocedure domains allows the clinicians to assess the local registration accuracy qualitatively. This can increase their confidence in using the US model for deriving needle guidance decisions.

Resumo: No presente trabalho propõe-se avaliar a existência de evidências clínicas e/ou radiográficas que identifiquem indivíduos com disfunção temporomandibular e da região cervical, bem como avaliar a eficácia da análise corporal computadorizada e da análise cefalométrica de Rocabado no diagnóstico destes pacientes. Para isso, foram avaliadas radiografias cefalométricas de perfil e fotografias de corpo inteiro de 100 pacientes, sendo 50 destes com sinais e sintomas de disfunção temporomandibular e 50 indivíduos assintomáticos, constituindo o grupo controle. A amostra foi selecionada a partir de ficha clínica de documentações ortodônticas em arquivo de uma clínica odontológica da cidade de Recife ¿ PE. Foi realizada avaliação fisioterapêutica das radiografias e fotografias, para fins de diagnóstico. Análise corporal e de Rocabado foram executadas para averiguação de sua aplicabilidade na detecção de desarmonias posturais da cabeça e dos segmentos corporais. As avaliações fisioterapêuticas diagnosticaram alterações posturais em ambos os grupos, sugerindo não existir associação entre elas e as disfunções temporomandibulares (p>0,05). Valores de Kappa indicaram que, na análise de Rocabado, o índice de curvatura da coluna cervical e o ângulo crânio-cervical apresentaram diagnósticos significantemente equivocados, o mesmo acontecendo com a predição da curva da coluna cervical pela análise fotográfica, não devendo, portanto, ser aplicados como instrumentos de diagnóstico. As análises corporais frontal, de perfil e de costas mostraram-se confiáveis quanto aos seus resultados, podendo ser utilizada como forma de avaliação de alterações posturais
Abstract: The aim of this paper was to evaluate the existence of clinical and/or radiographic evidences that identify patients with temporomandibular dysfunction and cervical region, as well as evaluating the effectiveness of the computerized corporal analysis and the cephalometric analysis of Rocabado in the diagnosis of these patients. In order to this, lateral cephalometric radiography and photographs of the entire body of 100 patients, being 50 of these with signals and symptoms of temporomandibular dysfunction and 50 asymptomatic individuals, constituting the control group. The sample was selected from the clinical information of orthodontic documentations in a file of a Dental clinic of the city of Recife - PE. It was carried through physiotherapeutic analysis of the x-rays and photographs for diagnosis ends. Corporal analysis and of Rocabado were executed for scertainment of its applicability in the detention of postural disharmony of the head and the corporal segments. The physiotherapeutics evaluations diagnosed postural alterations in both groups, suggesting not to exist association between them and the temporomandibular dysfunction (p>0,05). Values of Kappa indicated the same that, in the analysis of Rocabado, bending of the skull-cervical angle and the index column cervical were ignificantly presented making a diagnostic mistake, happening with the prediction of the curve of the cervical column for the photographic analysis, not having, therefore, to be applied as diagnosis instruments. The frontal corporal analyses of the profile and coasts revealed trustworthy how much to its results, being able to be used as form of evaluation the postural alterations

Background: Temporomandibular disorder (TMD) is a common and costly problem often leading to chronic pain. There exists moderate evidence for physical therapy (PT) interventions in the management of TMD. A known relationship between TMD and the cervical spine exists with some evidence to support cervical intervention treatments. Cervical spine thrust joint manipulation (TJM) is an effective PT intervention explored in a limited fashion for this population. Objectives: To determine the immediate and short term (1 and 4 week) effects of cervical TJM on pain, dysfunction, and perception of change in individuals with a primary complaint of TMD. Methods: In this single blind randomized clinical trial, individuals with TMD (n=50) were randomly assigned to receive cervical TJM or sham manipulation in 4 PT visits over 4-weeks. All participants also received behavioral education, a home exercise program, and soft tissue mobilization. Primary outcomes included jaw range of motion (ROM), Numeric Pain Rating Scale (NPRS), TMD Disability Index, Jaw Functional Limitation Scale (JFLS), Tampa Scale of Kinesiophobia (TSK-TMD), and Global Rating of Change (GROC). Self-report and objective measurements (with blinded assessor) were taken at baseline, immediately after baseline treatment, 1-week, and 4-weeks. A 2 x 4 mixed model ANOVA was used with treatment group as the between-subjects factor and time as the within-subjects factor. Separate ANOVAs were performed for dependent variables and the hypothesis of interest was the group by time interaction. Results: Statistically significant 2-way interactions were noted in JFLS (p = .026) and TSK-TMD (p = .008), favoring the thrust manipulation group. Both groups showed statistically significant main effects in all measures over time. GROC and PASS favored the thrust manipulation group with statistically significant differences in successful outcomes noted immediately after baseline treatment (NNT = 5) and at 4-weeks (NNT = 4). Conclusion: Both groups received identical multi-modal treatments with the addition of the randomized intervention: cervical TJM or sham manipulation. Differences between groups were small, however, improvements favored the TJM on all measures. Cervical TJM may be beneficial in the treatment of TMD.

This project presented a biomechanical model of the lumbosacral spine and pelvis, including novel methodologies associated with the measurement of human mechanics. This research has, for the first time, produced accurate three-dimensional geometric models of the human skeleton from living subjects using magnetic resonance imaging technology, enabling the prediction of physiological muscle action within individuals. The model was used to examine changes in the mechanics of the lumbopelvic musculoskeletal system between the standing and seated postures due to the increasing prevalence of the seated posture in the work and home environment. The outcomes of this research included a novel bone wrapping algorithm used to describe the effect of muscle-bone interactions. a novel method for creating three-dimensional in vivo spinal reconstructions using MRI, three dimensional in vivo helical axis measurements and subject specific normalised moment data.

Abstract: Introduction: Chronic low back pain is a disease with huge social and financial costs. The facet syndrome is one of the possible etiologies for low back pain, but its diagnostic and treatment remains intricate. Objective: To evaluate whether certain clinical and imaging criteria were able to identify patients with facet syndrome and confirm the diagnosis with injections performed in the operation room. Patients and methods: 38 patients of both genders attended at the Spine Surgery Ambulatory from Botucatu Medical School Clinical Hospital, had a specific physical examination evaluated, and were assessed using the Visual Analog Pain Scale; Oswestry Disability Index; EuroQoL-5D-5L and SF-36 Health Survey; and DRAM (The Distress and Risk Assessment Method) on day 1 and after 2 months. Thirty patients had their computed radiographs evaluated; twenty-four patients had their magnetic resonance imaging evaluated; and seven patients had their CT scans evaluated. The degenerative processes of the spinal structures were graded. All patients underwent facetary injections with 1 mL 0.5% levobupivacaine and 50 mg methylprednisolone (1 mL). Facet joints from L1 to S1 were treated bilaterally. Patients reported the pain generated by the touch of the tip of the needle on the facets and the remaining low back pain after 30 minutes of the procedure. Results: the mean age of the patients was 55.5 ± 11.6 years and 76.3% were female. The mean pain in orthostasis measured by the Visual Analogue Sca...

Quantitative knowledge of lumbar facet joint morphology is crucial in understanding the relationship between the geometry and kinematics of the facet joint as well as better understanding degenerative changes. Accurate prediction of lumbar facet joint contact area and stresses requires 3D representation of the thickness distribution of the articular cartilage of the facet joint. Several groups have reported on cervical facet joint cartilage thickness measurements using different approaches [2,3]. To the best of our knowledge, three-dimensional (3D) distribution of lumbar facet joint cartilage thickness has not been reported. Current methods of measuring various geometrical parameters of facet joint cartilage usually utilize high resolution magnetic resonance (MR) imaging techniques. Although these techniques represent the most up-to-date advanced methods in the soft tissue imaging field, facet joint cartilage reconstruction cannot be accomplished with reasonable fidelity using this approach. A study by Koo et al. [1] on knee joint cartilage showed that the accuracy of cartilage thickness measurement in the cartilage models derived from MRI (1.5T) varies with cartilage thickness. This study reported accurate measurements only for cartilage whose thickness ranged from 2.5 mm to 3.3 mm, which is in the range larger than the average lumbar facet joint cartilage assumed to be around 0.8 mm. Therefore, the objective of this study was to 1) analyze 3D lumbar facet joint cartilage thickness distributions based on laser scanner data, 2) compare this method using μCT and 3T MRI.

The design of spine implants requires a good understanding of spine kinematics and loading conditions. Realistic simulation of each functional spinal unit (FSU) requires capturing complicated contact and deformation of biological tissues in a computationally efficient manner. Specifically, the complexities include contacts in intervertebral and facet joints, restraints of spine ligaments, as well as realistic material properties of soft tissues. The variation in the stiffness among different FSUs is often neglected in spine modeling, which might be crucial for spine function. A hybrid approach for lumbar spine modeling was established that combined motion capture experiments, kinematic spine modeling and detailed finite element modeling. Motion capture data during flexion was collected and used to drive the spine model. For computational efficiency each FSU was modeled as an intervertebral connector (joint) element with different elastic behavior at each level. The connector behavior was calibrated using experimental data on the whole lumbar spinal motion (Wong et al. 2006) and cadaveric moment-rotation relationship of L45 (Heurer et al. 2007). Then the predicted stiffness for L23 was used to calibrate the material properties of a detailed FEM of L23.

Knowledge of the movements of the whole spine and lumbosacral joint is important for evaluating clinical pathologic conditions that may potentially produce unstable situations in human body movements. At present there are few studies that report systematic three-dimensional (3D) movement and force analysis of the whole spine. In this paper, a fully discretized bio-fidelity 3D musculoskeletal simulation model for biomechanical (kinematic) analysis of scoliosis for a patient with right thoracolumbar scoliosis is presented. It is important to note that this method can be used for modeling various types of scoliosis. It should be noted that this is the first time that such a detailed model of this kind has been constructed according to known literature. The combined loading conditions acting on the intervertebral joints and corresponding angles between vertebrae were analyzed during lateral bending through the motion capturing and musculoskeletal modeling of two female subjects, one with normal spine and the other with scoliosis. The scoliosis subject who participated in this study has thoracolumbar scoliosis with convexity to the right. Since lateral bending is one of the typical tasks used by clinicians to determine the severity of scoliosis condition, the motion data of the subjects in lateral bending while standing was captured. These motion data were assigned to train the musculoskeletal multi-body models for the inverse and forward dynamics simulations. The mobility of the ribcage, joint angle, as well as joint force were analyzed using the developed simulation model. According to the results obtained the combined loadings at the lumbar joints in the scoliosis model are considerably higher than the loads of the normal model in this exercise. This research has investigated the effect of thoracolumbar scoliosis on spinal angles and joint forces in lateral bending by the application of motion data capturing and virtual musculoskeletal modeling. The results of this study contribute to a better understanding of human spine biomechanics and help future investigations on scoliosis to understand its development as well as improved treatment processes.

The normal spine is a flexible column designed to maintain stability, position and can carry a considerable load. Degeneration weakens the spine by adversely affecting spinal stability, which is observed when a motion segment exhibits abnormally large displacements under applications of physiological load[1]. Furthermore, degeneration noticeably changes the load-bearing role of the intervertebral disc (IVD) during compression and extension by shifting significantly to the facet joint (FJ)[2].

Recent advances in the field of network embedding have shown that low-dimensional network representation is playing a critical role in network analysis. Most existing network embedding methods encode the local proximity of a node, such as the first- and second-order proximities. While being efficient, these methods are short of leveraging the global structural information between nodes distant from each other. In addition, most existing methods learn embeddings on one single fixed network, and thus cannot be generalized to unseen nodes or networks without retraining. In this paper we present SPINE, a method that can jointly capture the local proximity and proximities at any distance, while being inductive to efficiently deal with unseen nodes or networks. Extensive experimental results on benchmark datasets demonstrate the superiority of the proposed framework over the state of the art.

Facet joints are considered to play important roles in controlling spinal segmental motion and load transmission. It has been reported that 15–45% of low back pain is caused by facet joint diseases (1). Numerous studies on facet joint orientation have been reported in the literature; however, data on facet joint position is limited. Since the so-called “three-joint complex” is comprised of an intervertebral disc and two facet joints, it is important to determine the spatial relationship among these components to understand motion segment kinematics. Three-dimensional (3D) location of the facet joint may also provide important information for the studies on lumbar canal stenosis and spondylolisthesis. There has been no study, to our knowledge, to evaluate 3D position of the facet joint within the spine. The aim of this study was to determine accurately the facet joint position by using a subject-based computed tomography (CT) model and 3D measurement techniques, and analyze level, gender, ages and effects.

The COVID-19 pandemic has dealt a huge blow to every country, and many governments have struggled to meet their populations’ urgent needs during the crisis. The International Monetary Fund (IMF) has stepped in to offer extra support to a large number of countries during the pandemic. However, Oxfam’s analysis shows that as of 15 March 2021, 85% of the 107 COVID-19 loans negotiated between the IMF and 85 governments indicate plans to undertake austerity once the health crisis abates. The findings in this briefing paper show that the IMF is systematically encouraging countries to adopt austerity measures once the pandemic subsides, risking a severe spike in already increased inequality levels. A variety of studies have revealed the uneven distribution of the burden of austerity, which is more likely to be shouldered by women, low-income households and vulnerable groups, while the wealth of the richest people increases. Oxfam joins global institutions and civil society in urging governments worldwide and the IMF to focus their energies instead on a people-centred, just and equal recovery that will fight inequality and not fuel it. Austerity will not ‘build back better’.
