Abstract:
Background Headache is disabling and prevalent in idiopathic intracranial hypertension. Therapeutic lumbar punctures may be considered to manage headache. This study evaluated the acute effect of lumbar punctures on headache severity. Additionally, the effect of lumbar puncture pressure on post-lumbar puncture headache was evaluated. Methods Active idiopathic intracranial hypertension patients were prospectively recruited to a cohort study, lumbar puncture pressure and papilloedema grade were noted. Headache severity was recorded using a numeric rating scale (NRS) 0–10, pre-lumbar puncture and following lumbar puncture at 1, 4 and 6 hours and daily for 7 days. Results Fifty two patients were recruited (mean lumbar puncture opening pressure 32 (28–37 cmCSF). At any point in the week post-lumbar puncture, headache severity improved in 71% (but a small reduction of −1.1 ± 2.6 numeric rating scale) and exacerbated in 64%, with 30% experiencing a severe exacerbation ≥ 4 numeric rating scale. Therapeutic lumbar punctures are typically considered in idiopathic intracranial hypertension patients with severe headaches (numeric rating scale ≥ 7). In this cohort, the likelihood of improvement was 92% (a modest reduction of headache pain by −3.0 ± 2.8 numeric rating scale, p = 0.012, day 7), while 33% deteriorated. Idiopathic intracranial hypertension patients with mild (numeric rating scale 1–3) or no headache (on the day of lumbar puncture, prior to lumbar puncture) had a high risk of post- lumbar puncture headache exacerbation (81% and 67% respectively). Importantly, there was no relationship between lumbar puncture opening pressure and headache response after lumbar puncture. Conclusion Following lumbar puncture, the majority of idiopathic intracranial hypertension patients experience some improvement, but the benefit is small and post-lumbar puncture headache exacerbation is common, and in some prolonged and severe. Lumbar puncture pressure does not influence the post-lumbar puncture headache.

Abstract:
To evaluate the efficacy of subcutaneous administration of lidocaine for reducing physiologic instability in acutely ill newborns during clinically required procedures, 81 neonates who required lumbar punctures within the first month of life were stratified by birth weight and respiratory support and randomly assigned to an experimental or a control group. The experimental group received an injection of 0.1 mL/kg of 1% lidocaine prior to the lumbar puncture. The control group received a nonanesthetized lumbar puncture without placebo. Changes in heart rate, respiratory rate, transcutaneous oxygen and carbon dioxide tensions, and heart rate variability from baseline, preparatory (positioning/handling), lumbar puncture, and recovery periods were measured. The administration of lidocaine did not minimize physiologic instability in response to the lumbar puncture nor was it associated with any detectable adverse effects other than prolonging the duration of the lumbar puncture. Although significant physiologic changes were observed in response to preparatory procedures, few additional changes beyond those occurred in response to lumbar punctures in either the experimental or control group. It is concluded that local anesthesia failed to influence manifestations of physiologic instability during neonatal lumbar punctures and that preparatory procedures were more destabilizing than either the administration of lidocaine or the lumbar puncture itself. The results suggest that the management of newborns requires emphasis on minimizing the destabilizing effects of required and frequent handling procedures.

Abstract:
Local anesthesia decreases physiologic responses to pain in neonates but has not been used routinely during lumbar punctures in newborns, as it might obscure anatomical landmarks. However, local anesthesia may decrease newborns' struggling during lumbar puncture, thus facilitating the procedure and increasing its success rate. The success rate of lumbar punctures was compared in neonates allocated prospectively to 0.2 to 0.5 mL of 1% lidocaine anesthesia (n = 48) or a control group (n = 52). Newborns were held in a modified lateral recumbent postion (neck not flexed) and their struggling response to the various steps in the lumbar puncture was scored by the holder. The newborns' struggling motion score increased in response to lidocaine injection, but response to the subsequent spinal needle insertion was significantly decreased. Despite this decreased motion, no differences were noted in the number of attempts per lumbar puncture (1.9 ± 0.2 [SEM] in lidocaine and 2.1 ± 0.2 in control groups), rate of lumbar puncture failure (15% in lidocaine and 19% in control groups), or the number of traumatic lumbar punctures (46% in both groups). The success rate of lumbar puncture was not dependent on level of training of physicians performing the procedure. No acute complications, cerebrospinal fluid contamination, or subsequent meningitis was noted in either group. It is concluded that local anesthesia with lidocaine decreases the degree of struggling but does not alter the success rate of lumbar puncture in neonates. The practice of withholding lidocaine anesthesia from neonates undergoing lumbar punctures cannot be justified by arguing that it makes the procedure more difficult to perform.

Abstract:
Current international guidelines recommend that a cranial computed tomography (CT) be performed, on all HIV positive patients presenting with new onset seizures, before a lumbar puncture (LP) is performed. In the South African setting, however, this delay could be life threatening. This study sought to measure the number of cranial CTs that contraindicate an LP and to predict which clinical signs and symptoms are likely to pose an increased risk from LP. Methods: The study was performed at a district level hospital in the Western Cape. Data was collected retrospectively from October 2013 to October 2014. Associations between categorical variables were analysed using Pearson's Chi-squared test. Generalised linear regression was used to estimate prevalence ratios. Results 100 out of 132 patients were studied. Brain shift contraindicated an LP in 5% of patients. Patients with brain shift presented with: decreased level of consciousness, focal signs, head ache and neck stiffness. 25% of patients had a space occupying lesion (defined as a discreet lesion that has a measurable volume) or cerebral oedema. Multivariate analysis showed a CD4 count < 50 (p=0.033) to be a statistically significant predictor of patients with a space occupying lesion (SOL) and cerebral oedema. Univariate analysis showed focal signs (p=0.0001), neck stiffness (p=0.05), vomiting (p=0.018) and a GCS<15 (0.002) to be predictors of SOL and cerebral oedema.

Abstract:
Introdução: Procedimentos dolorosos de curta duração como o aspirado/biópsia de medula óssea e a punção lombar, com ou sem quimioterapia intratecal, são realizados com freqüência durante o tratamento de crianças com câncer. Estudos examinando diversos métodos de sedação para crianças submetidas aos procedimentos dolorosos têm mostrado diferentes resultados. Enquanto alguns investigadores sugerem que benzodiazepínicos e outras drogas intravenosas são eficazes, outros recomendam anestesia geral breve como sendo superior a todos outros modos de sedação O objetivo desde estudo é descrever a freqüência e a severidade das complicações da AMO/BMO e da PL sob anestesia geral. Pacientes e métodos: Um estudo observacional prospectivo foi realizado de Novembro de 2003 a Agosto de 2005. Pacientes com câncer e idade menor ou igual a 21 anos, em tratamento no Serviço de Oncologia Pediátrica do Hospital de Clínicas de Porto Alegre, submetidos a procedimentos de curta duração, diagnósticos e/ou terapêuticos, sob anestesia geral, no Centro Cirúrgico Ambulatorial. Resultados: Cento e trinta e sete pacientes foram submetidos a 423 procedimentos sob anestesia geral. Eram do sexo masculino 61%, com média de idade de 7,5 anos (0,2 a 21) e ASA II 98%. Oitenta e sete por cento dos procedimentos foram realizados em pacientes com leucemia ou linfoma. A maioria dos procedimentos não determinou eventos adversos durante os períodos intra-operatório e pós-operatório. Nenhum procedimento foi suspenso após iniciado. Um paciente teve dor lombar após o procedimento e foi internado com suspeita de hematoma subdural, o que foi descartado. Nenhum paciente necessitou reanimação cardiopulmonar ou tratamento em unidade de terapia intensiva. CONCLUSÃO: A anestesia geral para procedimentos dolorosos de curta duração, em crianças que realizam tratamento para neoplasias malignas, é segura quando realizada em centro cirúrgico ambulatorial por profissionais treinados.
Introduction: Painful short duration procedures like bone marrow aspiration/biopsy and the lumbar puncture with or without intrathecal chemotherapy are frequently performed during the treatment of children with cancer. Studies examining different methods of sedation for children undergoing painful procedures have shown different results. While some investigators suggest that benzodiapines and other intravenous drugs are efficacious, others recommend brief general anesthesia as being superior to all other modes of sedation. The objective of this study is to evaluate the frequency and severity of complications of BMA/BMB and LP under general anesthesia. Patients and methods: Prospective observational study performed from November 2003 to August 2005. Patients with cancer younger than 21 years old, receiving treatment at the Pediatric Oncology Unity of Hospital de Clínicas de Porto Alegre, undergoing diagnostic and/or therapeutic short duration procedures carried out under general anesthesia in the outpatient surgical unit. Results: One hundred and thirty seven patients were submitted to 423 procedures under general anesthesia. There were 61% boys, mean age of 7.5 years (0.2-21) and ASA II 98%. Eighty seven percent of the procedures were carried out in patients with leukemia or lymphoma. The majority of the procedures had no adverse events during intraoperative and postoperative periods. No procedure had to be suspended after it had begun. One patient had lumbar pain after procedure and was admitted to the ward with suspected subdural bleeding, but this was not confirmed. No patient needed cardiopulmonary reanimation or treatment in the intensive care unit. CONCLUSION: General anesthesia for short duration painful procedures in children undergoing treatment for malignancies is safe when carried out by trained professionals in outpatient surgical unit.

Abstract:
Introdução e Objetivos: O sistema nervoso central (SNC) é o um sítio freqüente de recaída na criança com leucemia linfocítica aguda (LLA). Existe evidência de que a punção lombar traumática (PLT) pode representar um risco adicional de recaída no SNC quando ocorre inoculação de blastos no liqüido céfalorraquidiano (LCR). Este estudo tem por objetivo determinar se a ocorrência da PLT ao diagnóstico afeta o prognóstico de pacientes com essa patologia. Material e Métodos: Setenta e sete pacientes com diagnóstico de LLA, tratados entre 1992 a 2002, foram incluídos na análise. Quimioterapia intratecal (QIT) foi instilada imediatamente após a PL inicial (precoce), ou na segunda PL (tardia), realizada no período de 24 a 48 horas após a realização da PL inicial. Foi feita análise da influência da PLT e do momento (precoce x tardia) de administração da QIT em relação a recaída no SNC. Resultados: Entre os 19 pacientes que apresentaram PLT ao diagnóstico e receberam QIT tardia, seis tiveram recaída isolada no SNC e dois recaída combinada em SNC e medula óssea (MO). Entre os nove pacientes que tiveram PLT e receberam QIT precoce, somente um apresentou recaída combinada em SNC e MO (P=0,20); não houve, portanto, influência estatisticamente significativa da PLT na sobrevida livre de eventos (SLE) (55% para QIT precoce x 49% para QIT tardia) (P=0,37). Entretanto, em análise estratificada, de acordo com grupos de risco, observamos que para pacientes de baixo ou médio risco o OR foi de 0,8 quando recebiam QIT tardia (P=0,99) e 0,17 quando recebiam QIT precoce (P=0,47). Por outro lado, entre pacientes de alto risco o OR para recaída foi de 21,0 para aqueles que recebiam QIT tardia (P=0,09) e 1,5 para o grupo que recebia Q IT precoce (P=0,99). Conclusão: Os resultados do presente estudo são sugestivos de que a ocorrência da PLT tem uma influência adversa no prognóstico de pacientes com LLA de alto risco de recaída. Como estes resultados são decorrentes de um estudo retrospectivo, recomenda-se que sejam confirmados em estudos prospectivos randomizados.
Introduction and Objectives: The Central Nervous System (CNS) is a frequent site of relapse in childhood acute lymphoblastic leukemia (ALL). Traumatic lumbar puncture (TLP) is thought to increase the risk of relapse in the CNS. This study sought to determine if TLP at the time of diagnosis affected the outcome of patients. Matherial and Methods: Seventy-seven newly diagnosed patients treated from 1992 to 2002 were included in the analysis. Intrathecal therapy (IT) was instilled either immediately after the diagnostic LP (early) or at a second LP (delayed) 24 to 48 hours following the diagnostic LP procedure. The authors carried out an analysis of the influence of TLP and the timing (early versus late) of administration of IT therapy on CNS relapse. Results: Among the 19 patients who had a TLP at diagnosis and received late IT therapy, six had isolated CNS relapse and two had combined CNS and bone marrow (BM) relapse. Among the nine patients who had TLP and received early IT therapy, only one had a combined CNS and BM relapse (P=0.20); the influence of TLP was not statistically significant on the event-free survival (EFS) (55% for early IT versus 49% for delayed IT) ( P =0.37). However, when we carried out a stratified analysis according to risk categories we found that for low and standard risk patients the odds ratio (OR) for relapse was 0.8 for delayed IT therapy (P=0.99) and 0.17 for early IT (P=0.47). On the other hand, among high risk (HR) patients the OR for relapse was 21.0 for delayed IT therapy (P=0.09) and 1.5 for early IT (P=0.99). Conclusion: The occurrence of TLP impacts adversely on prognosis of HR ALL patients. As these results are based in a retrospective study with a low number of patients, the authors recommend future trials using prospective randomized studies to confirm these findings.

Abstract:
Il n'existe pas de méthode non invasive validée pour déterminer la valeur absolue de la pression intracrânienne (PIC). Le liquide céphalorachidien (LCS) et le liquide cochléaire sont reliés par l'aqueduc cochléaire. Le but de ce projet est d'utiliser l'absorbance de l'oreille, optimale lorsque les structures vibrantes sont en position de repos, de sorte que les étriers lorsque la pression à l'extérieur de l'oreille (dans le conduit auditif externe -P_cae ) contrarie la PIC par les osselets de l'oreille moyenne. Les sujets ont été testés dans différentes positions d'inclinaison du corps, ce qui augmente la PIC, à l'aide d'un tympanomètre à large bande. 78 oreilles (sujets témoins entre 20 et 30 ans) ont montré que l'absorbance est maximale à toutes les fréquences à P_cae = 0 mmH2O en position début, elle diminue de façon complexe à P_cae zéro, mais à nouveau identique l'absorbance maximale à P_cae = 13 mm H2O ± 7 en position allongée, et 23 mm H2O ± 14 en position Trendelenburg (-30°), en 68 oreilles sur 78. Les 10 oreilles restantes présentaient un dysfonctionnement anatomique. Un modèle physique a été établi à partir d'un modèle d'oreille électromécanique classique, qui reproduit le comportement observé en attribuant à la PIC la cause des changements d'absorbance et en prédisant la capacité du P_cae pour compenser les changements d'absorbance dus à la PIC. De plus, 3 patients traités par un test de perfusion ont été testés, ainsi que 2 patients traités par ponction lombaire. Ces patients ont montré l'effet de la pression positive et négative dans les courbes d'absorbance. La littérature permet d'établir une corrélation entre la PIC absolue (dans chaque position du corps) et l'absorbance, nous pouvons conclure qu'en raison de la géométrie de l'oreille moyenne, la relation d'équilibre entre les valeurs absolues est PIC = 15 x P_cae , où 15 est le rapport des surfaces entre la MT et la platine de l’étrier. Des sujets suivis par une mesure invasive de la PIC seront nécessaires pour la continuation de cette étude
There is no validated non-invasive method for determining the absolute value of intracranial pressure (ICP). Ear connect cerebrospinal fluid (CSF) and cochlear fluid via cochlear aqueduct. The goal of this project is to use ear absorbance, optimal when the vibrating structures are in resting position, so the stapes when the pressure outside the ear (in the external ear canal -Peec) counteracts the ICP through the middle ear ossicles. Subjects are testing in different tilt body position, which increase ICP, using a tympanometer Wideband. 78 ears of control subjects between 20 and 30 years have shown that the absorbance is maximum at all frequencies at Peec = 0 mmH2O in standing posture, decreases in a complex way at zero Peec, but again identical to the maximum absorbance at Peec = 13 mm H2O ± 7 in supine, and 23 mm H2O ± 14 in Trendelenburg posture (-30 °), this in 68 ears out of 78. The remaining 10 ears had an anatomical dysfunction. A physical model was established from a classical electromechanical ear model, which reproduces the observed behavior by attributing to the ICP the cause of changes in absorbance and predicting the ability for Peec to offset the absorbance changes due to ICP. Furthermore, 3 patients treated with a perfusion test were tested as well as 2 patients treated by a lumbar puncture. These patients showed the effect of positives and negatives pressure in absorbance curves. Literature make possible a correlation between absolute ICP (in every tilt body position) and absorbance, we can conclude that due to the geometry of the middle ear, the equilibrium relationship between absolute values is ICP = 15 x Peec, where 15 is the ratio of the areas between the tympanic membrane and the stape plate. Subjects tested by invasive measurement of ICP will be required for the continuation of this study

Abstract:
Background: Lumbar punctures (LPs) are frequently performed in the paediatric medical emergency unit (MEU) department to diagnose or exclude meningitis. Unsuccessful lumbar punctures (LPs) cause diagnostic uncertainty which may prolong hospital stay and result in unnecessary antibiotic treatment and increased costs to the hospital and patients. It is important to determine factors that may be effective in reducing unsuccessful LPs. There is a paucity of studies on this topic from sub-Saharan Africa. Previous studies have shown inconsistent results and the use of sedation has not previously been studied. Aims: To determine the prevalence of unsuccessful lumbar punctures(LPs) and the factors influencing this in the medical emergency unit (MEU) and short stay ward (SSW) at Red Cross War Memorial Children's Hospital, Cape Town.

Trabalho Final do Mestrado Integrado em Medicina apresentado à Faculdade de Medicina
Lumbar puncture (LP) is a technique that allows access to the lumbar spinal subarachnoid space using a needle to collect cerebrospinal fluid (CSF). It is a procedure that is frequently performed in pediatric emergency departments. Our aim was to analyze how LP is performed in pediatrics in Portugal.National study was conducted, by applying an anonymous online questionnaire with 20 questions about LP technique, through Pediatric Emergency Society of the Portuguese Society of Pediatrics contacts. A total of 190 questionnaires were analyzed in which 67.9% (n=129) were specialists and 32.1% (n=61) were pediatric residents. The majority (79%) routinely used analgesia and/or sedation and 53.2% (n=101) do not allow the parents to be present during the procedure.A large proportion of physicians (43.7%) prefer to place the child in lateral decubitus and 43.2% decide the position to place the child according to age. Most referred to use Quincke needles (60%). Butterfly needle was used in 25.8% (n=49) when referring to newborns. There was a more frequent use of this type of needle in the group of specialists (30.2% vs 16.4%, p=0.071). Only 24.7% of physicians orient the needle bevel parallel to the longitudinal fibers of the dura, and the group of pediatric residents performed it more frequently than the group of pediatricians (39,7% vs 17,5%, p=0.001). The majority of doctors recommend rest after the procedure. Our study was the first to describe how LP is performed in children in Portugal. It reinforces the need to create a national protocol for this procedure in children. It is also important that medical schools and training hospitals create simulation trainings and courses, to not only teach the correct technique and enhance skills, but also to improve self-confidence.

A maioria referiu usar agulhas tipo Quincke (60%). Foi descrito que as agulhas do tipo borboleta foram utilizadas em 25,8% (n=49) quando a PL é realizada em recém-nascidos. Os especialistas utilizam esta agulha mais frequentemente (30,2% vs 16,4%, p=0,071).Apenas 24,7% dos médicos orientam o bisel da agulha paralelamente às fibras longitudinais da dura-máter, e o grupo de internos praticam esta técnica com mais frequência do que o grupo de pediatras (39,7% vs 17,5%, p=0,001).A maioria dos médicos recomenda descansar após o procedimento.O nosso estudo foi o primeiro a descrever como a PL é realizada em crianças em Portugal, o que reforça a necessidade de criar um protocolo nacional para a realização deste procedimento em crianças. Também é importante que as escolas médicas e os hospitais universitários criem treinos e cursos de simulação, não apenas para ensinar a técnica correta e aprimorar as aptidões, mas também para melhorar a autoconfiança.

Original research submitted as partial fulfillment of the requirements for the Masters in Medicine degree in Orthopaedic surgery at the University of Witwatersrand, Johannesburg, April 2014
Objectives 1. Assessment of radiological parameters of spinal stenosis using Magnetic Resonance imaging. 2. Clinical assessment of patients with Oswestry disability index and Neurogenic claudication outcome score questionnaires. 3. To assess correlation between clinical assessment questionnaires’ scores and radiological parameters. Background. Spinal stenosis is a common presentation in the elderly and a reason for surgical intervention. Diagnostic criteria are still inconclusive. There is poor correlation between clinical and radiological findings. New observations have been described and whether they improve diagnostic criteria remains to be seen. Methods. 30 patients with spinal stenosis were included in the study. The 2 questionnaires were administered and Magnetic Resonance Imaging copies were obtained. Questionnaires and images were analyzed. Osirix programme was used to analyze the images and do the measurements. Data was entered onto an excel sheet and analyzed using Statistica software. Frequencies and correlations were done. Results. The age range was between 41 and 85.There were 22 females and 8 males. L4/L5 was the commonest level involved in 23 patients. Multilevel involvement was 23% and those patients had a higher morphological grade, which was statistically insignificant. The commonest morphological grade was C. Sedimentation was positive in 93% of the patients. The Oswestry disability Index and Neurogenic Claudication Outcome score were negatively correlated, which was statistically significant, p = 0.0004. There was no correlation between clinical and radiological features. Conclusion. Spinal stenosis remains a clinical dilemma. There is variability within the population and lack of correlation between clinical and radiologic features. Radiological features however correlate with each other, but do not help with optimizing patient care.

Abstract:
Diagnosis, repair and regeneration of the disc often necessitate needle injection to the nucleus pulposus through the annulus. Discography in which a radio opaque material is injected into the nucleus and electrothermal treatment involving inserting a catheter into the disc requires disruption of the annulus through needle puncture. Annulus puncture may also be required during placement of nucleus implants. Needle puncture is also used to inject growth factors, gene and cell therapy for regeneration of the disc. In animal models, disc degeneration is induced over time by needle puncture of the annulus. The severity of the degeneration depends on the magnitude of the annulus needle puncture. One thing that is not clear is how much of the observed changes in the disc biomechanics and biochemical changes are due to nucleus treatment and how much is due to annular disruption through needle puncture. Animal model studies have shown that significant changes in disc mechanics were noticed within 1 week of needle puncture with a large-gauge needle. Another in-vitro animal study showed that biomechanical changes were observed in the disc when the ratio of needle diameter to disc height is greater than 40%. All these studies were focused on the effect of small number of needle diameters and addressed using animal cadaver models. How these needle puncture injury studies on small and large animal models can be extrapolated to human conditions is still not known. Thus there is need to evaluate effect of range of needle puncture diameters in human lumbar disc biomechanics. The purpose of this study is, with the help of a finite element models, quantify the biomechanical effect due to varying size of needle punctures in a human lumbar intervertebral disc.

Abstract:
Introduction: Simulation has progressively been recognized as a reliable teaching method for delicate medical procedures, including lumbar punctures, an important diagnostic and therapeutic tool. Despite its importance, studies show training to be insufficient, with medical students and residents feeling technically unprepared. Furthermore, multiple challenges lie ahead of implementing curricular training, including costs of simulators, available for prices ranging from US$ 1158,89 to US$ 2.897,21 a unit. Because the technique does not require complex events, selecting a type of simulator can be compatible with simpler but realistic devices that can be made at teaching institutions, not requiring third party suppliers. Objectives: To construct a low-cost lumbar puncture simulator for medical education. Methods: Based on literature and professional experience, critical points of construction and resources available on the market were assessed. A prototype was confectioned with processed vertebrae, sponges, a latex tube filled with water, attached to a syringe for pressure, and makeshift skin and soft tissue from a commercial suture kit, all mounted on a metal apparatus. Results: The simulator concocted of the most cost-effective materials and only the most crucial components performed comparably to brand models according to pre-tests by selected students and experienced professionals. Currently, a more reproductible prototype is being constructed out of 3Dprinted materials, which will be further evaluated and validated. Conclusion: The rough prototype performs comparably to commercial models, and we believe the study will further corroborate modern tendencies to transform teaching into cost-effective techniques that enrich medical education in resource-limited settings.

Abstract:
Back pain is a debilitating medical condition, often with an unclear source. Over time, back pain can affect the work and lifestyle of an individual by reducing job productivity and time spent on enjoyable activities. Discography of the intervertebral disc (IVD) is often used to diagnose pathology of the disc and determine if it may be a source for chronic back pain. It has recently been suggested that discography may lead to IVD degeneration, and has been a cause of controversy among spine care physicians. Using the results from a cadaveric experimental model, a finite element model was first validated. Then, a study was conducted to better understand the changes caused by discography on human spine mechanics. An anatomically accurate L3-L5 lumbar spine model was developed using computed tomography scans. Discography was simulated in the model as an area in the disc affected by needle puncture. The material properties in the nucleus pulposus were adjusted to match experimental data both before and after puncture. The results show that puncture of the IVD leads to increased deformation as well as increased stresses in the disc. Pressure in the nucleus pulposus found to decrease after puncture, and was calculated in the course of this study. Puncturing the IVD changes disc mechanics and may lead to progressive spine issues in the future such as disc degeneration. While discography has been the gold standard to determine if the disc was a source of back pain in patients for many years, the potential long-term degenerative effects of the procedure are only now coming into light, and must be closely examined.

Abstract:
Biomechanics of optic nerve head (ONH) has attracted increasing attention in recent years due to its association with ganglion cell damage and tissue remodeling resulted vision impairments [1, 2]. The ONH is exposed to both intraocular pressure (IOP) and intracranial pressure (ICP), separated by the lamina cribrosa (LC) which is regarded as the primary site of axonal injury in glaucoma[3]. The elevated IOP was widely acknowledged as a major risk factor for glaucoma. However, a large number of glaucoma patients never have an increase in IOP [4]. In studies that have looked at lumbar puncture (LP) data, patients with open-angle glaucoma were found to have lower ICPs than non-glaucomatous controls[5]. It suggests that higher translaminar pressure difference across the LC rather than IOP alone may have an important role in the pathogenesis of ONH damage. There were few computational models had been established to investigate the ICP’s role on ONH, such as Ethier et al. found elevated ICP could induce decreased strain within LC using finite element model[6]. However, less experimental data are available for delineating the role of ICP on the behaviors of LC. In this work, we present one dataset from LP patients and reconstruct its two-dimensional computational model of the ONH based on the patient’s images to delineate the role of ICP on ONH mechanics. The changes of LC depth, BMO width and papillary height were compared between the simulation and clinical dataset. The maximum principal strain of LC was calculated to reinforce its link with mechanosensitive cells in ONH.
