Abstract:
Objectives: Bone densitometry is widely used to evaluate osteoporosis; however, it is pointed out that bone density may be high in the case of fractures, deformities, and osteosclerotic changes. The present study evaluated bone density measured at our hospital and evaluated its correlation with the presence or absence of lumbar spine fractures. Methods: Bone density of the lumbar spine and femur was measured in 185 patients from July 2017 to June 2019 at our hospital, and the presence or absence of a lumbar spine compression fracture was evaluated on the basis of the image. Information regarding age, sex, lumbar bone density, presence or absence of lumbar fracture, number of lumbar fractures, and grade of lumbar fracture was also statistically evaluated. Results: Analysis was performed for 185 patients (20 males and 165 females, average age 76.9 ± 7.5 years). The bone density was 0.830 ± 0.229 of compression fractured bodies (number of vertebral bodies were 132) and 0.765 ± 0.178 g/cm3 of noncompression fractured bodies (number of vertebral bodies was 608). Discussion: The presence of lumbar fractures significantly increases bone density. For diagnosing osteoporosis, both bone density and the possibility of lumbar spine fractures must be considered.

Abstract:
ABSTRACT Objective: This research presents a biomechanical analysis performed in the lumbar spine of a porcine animal model, considering a minimally invasive technique for the treatment of split fractures. Methods: Porcine spines were used to perform compression tests, considering three different approaches. Three groups were defined in order to verify and validate the proposed technique: a control group (1); spines with split fractures (2); and a treatment group (3). For the first group (control), spines were axially compressed until any kind of fracture occurred, in order to verify the strength of the structure. In the second group, split fractures were created to obtain the mechanical failure pattern of the model. In the third group, the split fractures were submitted to the proposed treatment, to verify the resistance achieved. The three groups were compared by means of axial compression tests. Statistical analysis was performed by ANOVA. Results: The control group (intact spine) and the treated split fracture group presented similar results (p>0.05), differing from the results for the untreated split fracture group (p<0.05). Conclusions: The tests performed in order to determine the behavior and strength of the lumbar spine when subjected to axial compression provided positive data for the development of a minimally invasive technique capable of restoring split fractures of the spine.

Abstract:
Thoracolumbar fractures change the biomechanics of the spine. Load distribution causes kyphosis by the time. Treatment of posttraumatic kyphosis is still controversial. We reviewed the literature between 2010 and 2020 using a search with keywords “thoracolumbar fracture and kyphosis.” We removed osteoporotic fractures, ankylosing spondylitis fractures, non-English language papers, case reports, and low-quality case series. Up-to-date information on posttraumatic kyphosis management was reviewed to reach an agreement in a consensus meeting of the World Federation of Neurosurgical Societies (WFNS) Spine Committee. The first meeting was conducted in Peshawar in December 2019 with WFNS Spine Committee members’ presence and participation. The second meeting was a virtual meeting via the internet on June 12, 2020. We utilized the Delphi method to administer the questionnaire to preserve a high degree of validity. We summarized 42 papers on posttraumatic kyphosis. Surgical treatment of thoracolumbar kyphosis due to unstable burst fractures can be done via a posterior only approach. Less blood loss and reduced surgery time are the main advantages of posterior surgery. Kyphosis angle for surgical decision and fusion levels are controversial. However, global sagittal balance should be taken into consideration for the segment that has to be included. Adding an intermediate screw at the fractured level strengthens the construct.

Abstract:
OBJECT The treatment of traumatic burst fractures unaccompanied by neurological impairment remains controversial and ranges from conservative management to 360° fusion. Because of the heterogeneity of fracture types, classification systems, and treatment options, comparative biomechanical studies might help to improve our knowledge. The aim of the current study was to create a standardized fracture model to investigate burst fractures in a multisegmental setting. METHODS A total of 28 thoracolumbar fresh-frozen human cadaveric spines were used. The spines were dissected into segments (T11–L3). The T-11 and L-3 vertebral bodies were embedded in Technovit 3040 (cold-curing resin for surface testing and impressions). To simulate high energy, a metallic drop tower was designed. Stress risers were used to ensure comparable fractures. CT scans were acquired before and after fracture. All fractures were classified using the AO/OTA classification. RESULTS The preparation and embedding of the spine segments worked well. No repositioning or second embedding of the specimen, even after fracture, was required. It was possible to create single burst fractures at the L-1 level in all 28 spine segments. Among the 28 fractures there were 16 incomplete burst fractures (Type A3.1), 8 burst-split fractures (Type A3.2), and 4 complete burst fractures (Type A3.3). The differences before and after fracture for stiffness and for anterior, posterior, and central heights were all significant (p < 0.05). CONCLUSIONS The ability to create reproducible burst fractures of a single vertebral body in a thoracolumbar spine segment may serve as a basis for future biomechanical studies that will provide better understanding of mechanical properties or fixation techniques.

Abstract:
The aim of this study is to report the rare occurrence of simultaneous double spine fractures in a patient with progressive ankylosing spondylitis (AS). An 82-year-old male with established AS had low-energy falls. He had sustained simultaneous double spine fractures and died. Plain radiographs of the cervical spine were unremarkable in detecting a cervical spine fracture in a patient with AS and a spinal cord injury following a fall. CT scan showed a displaced fracture at the C6/C7 with American Spinal Injury Association-A spinal cord injury and displaced fracture at L1. The cause of death was determined to be upper spinal cord injury caused by cervical spinal fracture and dislocation that were facilitated by spinal rigidity from AS. This case report illustrates the importance of obtaining a detailed medical history and thorough imaging study when investigating deaths, including nonfatal conditions, such as AS. Furthermore, it shows the value of entire spine CT scan in the evaluation of the mechanism, further spine fractures, and manner of death. Despite the occurrence of spine fracture in AS patients, simultaneous double or multiple spine fractures are extremely rare and can be missed. Care should be taken for the further spine fracture in the entire spine in patient with AS.

Abstract:
Jefferson fractures of the immature spine have received little attention in the study of pediatric spinal trauma. Fractures through synchondroses are a possibility in the immature spine, in addition to fractures through osseous portions of the vertebral ring, and they create opportunities for misinterpretation of diagnostic imaging. The authors describe 3 examples of Jefferson fractures in young children. All 3 cases featured fractures through an anterior synchondrosis in association with persistence of the posterior synchondrosis or a fracture of the posterior arch. The possibility of a Jefferson fracture should be considered for any child presenting with neck pain, cervical muscle spasm, or torticollis following a head injury, despite a seemingly normal cervical spine study. Jefferson fractures in young children are probably much more common than previously recognized.

Abstract:
Introduction: Surgical treatment of displaced acromial and scapula spine fractures may be challenging due to the bony anatomy and variable fracture patterns. This difficulty is accentuated by the limitations of the available scapular plates for fracture fixation. This study compares the quantitative fitting of anatomic scapular plates and clavicle plates, using three-dimensional (3D) printed fractured scapulae. Methods: Fourteen scapulae with acromion and spine fractures were used for this study. Computerized tomographic (CT) scans of the fractured scapulae were obtained from the Philips picture archiving and communication system (PACS) database of patients admitted to a tertiary teaching hospital in Cape Town, South Africa between 2012 and 2016. The reconstructed scapulae were 3D printed and the anatomical acromion and clavicle plates were templated about the fracture regions. The fit assessment was performed by five observers who classified the plates as no-fit, intermediate fit, and anatomical fit according to the surgical guidelines. Results: The 6-hole anterior clavicle plate performed better than any of the scapular plates as they were able to fit 45.7% of the fractured acromion, including the spine. Among the pre-contoured anatomical scapula plates, both the short and the long acromion plates could fit only 27.3% of the fractured acromion. The intraclass correlation coefficient was 0.965 suggesting excellent consensus among the five observers. Conclusion: Clavicle plates were found to be better suited to fit around a scapula fracture in its acromion and spine region.

Abstract:
Background. Spina bifida is a serious defect in the development of the spine and spinal cord. It is accompanied by several orthopedic disorders of the spine and lower limbs, including fractures of long tubular bones. In spina bifida, osteoporosis plays an important role in the pathogenesis of motor disorders. Aim. The objective was to determine the patterns of occurrence and the clinical and radiological features of fractures of the long tubular bones of the lower limbs in children with sequelae of spina bifida. Materials and methods. From 2006 to 2017, 544 patients with spina bifida were examined and treated at the Turner Research Institute for Children’s Orthopedics. Clinical-neurological and radiographic methods were used. The neurosegmental level of spinal cord involvement was determined using the Sharrard classification, and the motor level was assessed according to the method proposed by Melbourne Medical University. Results. The clinical picture of a fracture of a long tubular bone in a child with spina bifida has many characteristics. There was no abnormal mobility in the fracture site in 56% of cases, edema was absent in 88% of children, and pain in the fracture region was observed in only 19% of cases. The radiographic features of the atypical fracture of long tubular bones in children with sequelae of spina bifida included lack of a fracture line, presence of a hypertrophic periosteal reaction, and sclerosis areas at the fracture site. Conclusion. The frequency and localization of fractures of the lower limbs in children with sequelae of spina bifida are determined according to the neurosegmental level. The clinical picture of fracture often differs from usual fractures by the absence of pain syndrome, edema in the fracture region, and displacement of bone fragments, which must be considered for diagnosis. The peculiarities of the clinical and radiological picture are associated with the presence of osteoporosis in this pathology due to a decrease in the motor activity level of the patients.

Vertebral fractures are the most common complication of osteoporosis and are associated with significant pain, height loss, disfigurement, respiratory impairment, depression, and decreased life span. Despite the high personal and societal costs of vertebral fractures, little is known regarding their biomechanical etiology. In particular, whereas much is known about the determinants of vertebral strength, little is known about the in vivo loading of the spine that may contribute to vertebral fracture. Prior efforts to understand the possible contribution of spine mechanics to vertebral fractures have been limited by the inability to accurately assess in vivo spinal loading, especially in the thoracic region. Thus, the overall goal of this work was to improve the understanding of vertebral fractures through detailed analysis of spinal loading. We first developed and validated a novel musculoskeletal model capable of predicting forces in the thoracolumbar spine during daily activities. Model-derived predictions of vertebral compressive loading and trunk muscle activity were highly correlated with previously collected in vivo measurements of pressure, vertebral compression from telemeterized implants, and trunk muscle myoelectric activity from electromyography. To gain insights into how individual variation in trunk anatomy influences vertebral loading, we developed a robust set of methods for rapid, automated generation of subject-specific musculoskeletal models of the thoracolumbar spine using computed tomography based measurements of spine curvature and trunk muscle morphology. Using these subject-specific models, we found that normal variations in spine curvature and muscle morphology in the adult population have a large effect on vertebral loading predictions. Specifically, we found that increasing thoracic kyphosis and reducing lumbar lordosis, changes that commonly occur with age, were both associated with higher spinal loads. Lastly, we used our musculoskeletal model to describe how vertebral loading and the factor-of-risk (load-to-strength ratio) vary along the spine for a large number of activities. For a majority of activities, the highest loads and factor-of- risk were in the thoracolumbar region, which is the spine region with the highest incidence of vertebral fracture. Further, we identified a unique biomechanical mechanism responsible for the high loads in this region.

Abstract:
Thesis (Ph.D.)--Boston University
Vertebral fractures are the hallmark of osteoporosis, yet the failure mechanisms involved in these fractures are not well understood. Current approaches to predicting fracture risk rely on average measures of bone mineral density in the vertebra, which are imperfect predictors of vertebral strength and poor predictors of fracture risk. Prior research has established that substantial regional variations in density exist throughout the vertebra and has suggested several biomechanical consequences of these variations. The overall goal of this dissertation was to characterize failure mechanisms in human vertebrae, with specific emphasis on the role of intra-vertebral heterogeneity in density and microstructure and on identifying clinically feasible techniques for predicting fracture risk. Using images obtained from micro-computed tomography (μCT) and quantitative computed tomography (QCT), the intra-vertebral heterogeneity in bone density was quantified in cadaveric specimens. Quantitative measures of this heterogeneity improved predictions of vertebral strength as compared to predictions based only on mean density. Subsequently, the intra-vertebral heterogeneity in density was measured via QCT in a cohort of post-menopausal women and was found to be lower in those who had sustained a vertebral fracture vs. in age-matched individuals without fracture. The next set of studies focused on assessing the accuracy of finite element (FE) models for predicting vertebral failure. Digital volume correlation (DVC) was used to measure the deformations sustained throughout the vertebra during compression tests. These results were compared against deformation patterns predicted using FE models created from QCT images of the vertebrae. Good agreement was found between predicted and measured deformations when the boundary conditions were accurately defined, despite simplifications made in representing material properties. The outcomes from this dissertation demonstrate that the intra-vertebral heterogeneity in density contributes to bone strength and has promise as a clinically feasible indicator of fracture risk. OCT-based FE models, which by definition account for this heterogeneity, are another promising technique, yet will likely require non-invasive techniques for estimating vertebral loading to provide the requisite accuracy in failure predictions. These two engineering approaches that account for the spatial heterogeneity in density within the vertebra may lead to more sensitive and specific indicators of fracture risk.

Objective: This research paper reports on the radiographic outcome of unstable thoracolumbar injuries with short segment posterior instrumentation as standalone treatment; in order to review rate of instrumentation failure and identify possible contributing factors. Background: Short segment posterior instrumentation is the treatment method of choice for unstable thoracolumbar injuries in the Acute Spinal Cord Injury Unit (Groote Schuur Hospital). It is considered adequate treatment in fracture cases with an intact posterior longitudinal ligament, and Gaines score below 7 (Parker JW 2000); as well as fracture dislocations, and seatbelt-type injuries (without loss of bone column - bearing integrity). The available body of literature often states instrumentation failure rates of up to 50% (Alanay A 2001, Tezeren G 2005). The same high level of catastrophic hardware failure is not evident in the unit researched. Methods: Sixty-five consecutive patients undergoing the aforementioned surgery were studied. Patients were divided into two main cohorts, namely the “Fracture group” (n=40) consisting of unstable burst fractures and unstable compression fractures; and the “Dislocation group” (n=25) consisting of fracture dislocations and seatbelt-type injuries. The groups reflect similar goals in surgical treatment for the grouped injuries, with reduction in loss of sagittal profile and maintenance thereof being the main aim in the fracture group, appropriately treated with Schantz pin constructs; and maintenance in position only, the goal in the dislocation group, managed with pedicle screw constructs. Data was reviewed in terms of complications, correction of deformity, and subsequent loss of correction with associated instrumentation failure. Secondly, factors influencing the aforementioned were sought, and stratified in terms of relevance. Results: Average follow up was 278 days for the fracture group and 177 days for the dislocation group (all patients included were deemed to have achieved radiological fusion – if fusion technique was employed). There was an average correction in kyphotic deformity of 10.25 degrees. Subsequent loss in sagittal profile averaged 2 degrees (injured level) and 5 degrees (thoracolumbar region) in the combined fracture and dislocation group. The only factor showing a superior trend in loss of reduction achieved was the absence of bone graft (when non-fusion technique was employed). Instrumentation complications occurred in two cases (bent connection rods in a Schantz pin construct with exaggerated loss in regional sagittal profile, and bent Schantz pins). These complications represent a 3.07% hardware failure in total. None of the failures were considered catastrophic. Conclusion: Short segment posterior instrumentation is a safe and effective option in the treatment of unstable thoracolumbar fractures as a standalone measure.

Abstract:
Background: Axis fractures are a common injury in the elderly population. Treatment is often complicated due to osteoporosis and patient comorbidity. Knowledge of the incidence of these fractures, as well as their treatment, outcome and mortality rate, will improve knowledge and decision-making processes for this fragile group of patients. Objectives: This thesis aims (1) to review the literature on the non-surgical and surgical treatment of odontoid fractures type 2 in the elderly population, (2) to provide an updated overview of axis fracture subtypes, their incidence and their treatment in a cohort in two university cities, (3) to map the incidence of fractures and the treatment of these patients in Sweden, (4) to investigate the effect on mortality of both the surgical and non-surgical treatment of axis fractures and (5) to present the protocol for a randomized controlled trial (RCT) on the treatment of odontoid fractures type 2 in the elderly population. Methods: A systematic review was performed using the MeSH keywords “odontoid AND fracture AND elderly”. The data for the cohort study were extracted from the regional hospital information system. The radiographs were reviewed retrospectively. Data were extracted from the Swedish National Patient Registry (NPR) and the mortality registry for the national registry studies. Finally, the RCT protocol was carried out according to the SPIRIT and CONSORT statements for clinical trial reporting. Results and conclusions: So far, there has been a scarcity of existing evidence on treatment of odontoid fractures type 2 in the elderly population. In this thesis, we found in two university cities an increased incidence, and a trend towards more surgical treatment of type 2 and 3 odontoid fractures 2002-2014. Between 1997 and 2014 in Sweden, there was an increasing incidence of C2 fractures, but the treatment trend went towards more non-surgical treatment. Surgically treated patients had a greater survival rate than non-surgically treated patients. Among those over 88 years of age, surgical treatment lost its effect on survival. In the RCT we will study the function of patients with odontoid fractures type 2 and by comparing non-surgical treatment with posterior C1-C2 fusion, the cost-effectiveness of the treatment options.

Abstract:
Biomechanical research was conducted to outline mechanisms of cervical and lumbar vertebral body burst and wedge fractures using spines obtained from post-mortem human subjects (PMHS) and animals [1–5]. These studies incorporated full columns [1, 2] or, more commonly, three-body vertebral segments [3–6]. The method of load application most often involved static specimen placement with dynamic load application to the superior fixation using a weight-drop method or an MTS piston. While these studies experimentally induced vertebral body burst fractures, as clinically demonstrated following abrupt and severe axial loading through the pelvis, fractures resulted from unrealistic experimental boundary conditions. For example, three-body vertebral segments remove effects of spinal curvature and weight-drop or piston load application to the cranial fixation does not replicate the acceleration-driven loading as applied to the base of the spine, wherein characteristics of the acceleration versus time pulse are important in injury type and severity. Therefore, the present study developed an experimental model to mimic real-world loading situations resulting in vertebral body burst and wedge fractures.

Abstract:
Abstract Fractures of the odontoid process of the second cervical vertebra comprise 7–13% of all cervical spine fractures. Anderson and D’Alzono [1974] have classified these fractures into three categories: Type I, Type II, and Type III. Type I fractures are oblique, usually avulsion, fractures of the superior-most aspect of the odontoid. Type II fractures, the most commonly-occurring, are produced at the juxtaposition of the process and the C2 body. Type III fractures involve propagation of the fracture through the C2 body.

Abstract:
The sacrum fractures are very severe trauma which frequently accompanied with lumbar spine fractures. The surgical procedures often require primary stabilization of both lumbar spine and sacrum. To understand the rationale of the instrumentation numerous cadaveric studies were conducted to elucidate the anatomy of fractures and treatment options [1,2,3]. The modern computer technology allowed simulating the fractures and repairing using the Finite Element Analysis, also [4,5]. The last method has a raw of advantages versus cadaveric method such as higher reliability, accuracy, and safety. Finite element investigations of the pelvic fractures allowed comparing the influence of implants on pelvis stability. However, the extensive search of the literature failed to find a finite element model which includes the pelvis and lumbar spine together. Current study is the first step to accomplish this goal. An experimentally validated model of ligamentous lumbar spine was combined with the FE model of pelvis [7], and simulation of the sacrum fractures was conducted.

Abstract:
Osteoporosis is a skeletal disease characterized by low bone mass and deterioration of bone tissue. It affects 15–20 million women in the United States. Fractures of the vertebrae, wrist and hip are the most common. [1] In the spine, osteoporosis greatly affects the bone mass of the vertebral bodies (VB), the primary structures for transmitting loads in the spine. The VB is comprised of a shell of dense bone surrounding a more porous bony tissue called trabecular bone. Trabecular bone is a lattice-like network of trabeculae in the shape of plates or rods, depending on orientation and one’s age. When the weakened trabecular structure experiences a loss of height, acute back pain, spinal cord compression, and overall loss of mobility can ensue. A single fracture creates a region of high stress in the trabecular network, often leading to more fractures. In almost 20% of the cases one fracture in a VB may result in a secondary fracture within a one year period. [2] Many fractures go unnoticed. The high occurrence, frequent uncertainty of fracture, and gravity of subsequent injury indicate a need to improve the strength of osteoporotic vertebrae before damage can occur. It may be desirable to treat weakened bone prior to fracture. One candidate for prevention that is investigated in this study is vertebroplasty. Currently, the procedure is used to repair fractured VB by injecting acrylic bone cement into the affected level. A parametric finite element (FE) investigation and supporting experimental study was conducted to evaluate the usefulness of vertebroplasty as a preventative treatment.

Abstract:
Osteoporotic and age-related fractures are a significant public health problem. One of the most common osteoporotic fracture sites in the aging population is distal radius. There is evidence in the literature that distal radius fractures (Colles’ fracture) are an indicative of increased risk of future spine and hip fractures [1]. Therefore, developing new methods for accurate evaluation of human radius fracture risk is necessary. The previous studies showed that geometrical properties of the radius correlate with its fracture load [2]. However, the combined effect of geometrical and material properties on fracture load has not been studied.
