Conjoint nerve root (CNR) is an embryological nerve root anomaly that mainly involves the lumbosacral region. The presence of CNR during tubular discectomy raises the chances of failure in spinal surgery and the risk of neural injuries. Tubular discectomy can be challenging in the presence of CNR owing to limited visualization. Read More

Background: Charcot spinal arthropathy, also known as Charcot spine and neuropathic spinal arthropathy, is a progressive and destructive condition that affects an intervertebral disc and the adjacent vertebral bodies following loss of spinal joint innervation. We report the first case of Charcot spinal arthropathy (CSA) associated with cerebrospinal fluid (CSF)-cutaneous fistula.

Case Presentation: A 54-year-old male who underwent T10-L2 posterior instrumented spinal fusion seven years prior for treatment of T11 burst fracture and accompanying T11 complete paraplegia visited our department complaining of leakage of clear fluid at his lower back. Read More

The objective of this study was to determine force-based lumbar spine injury criteria due to vertical impact using Post Mortem Human Surrogate (PMHS) experiments. Mounted personnel in military vehicles sustain loads from the pelvis in combat events such as underbody blast loadings. Forty-three post mortem human subject thoracolumbar spinal columns were obtained, screened for pre-existing trauma, bone mineral densities (BMDs) were determined, pre-test radiological images were taken, fixed at the ends in polymethylmethacrylate, load cells were attached to the ends of the fixation, positioned on custom vertical accelerator device based on a military-seating posture, and impacted at the base.

Background: Lumbar disc herniation (LDH) is 1 of the most common diseases in orthopedics, which seriously affects people's daily life and brings a heavy burden on society and families. Chinese herbal medicine has been used in clinical practice for a long time and Duhuo Jisheng Decoction (DHJSD) is believed to help alleviate the symptoms of LDH. This systematic review aims to collect evidences from randomized clinical trials and evaluate the efficacy of DHJSD on LDH in order to provide a reference for clinicians and researchers. Read More

Background: Lumbar total disc replacement is increasingly becoming a more common treatment for discogenic low back pain refractory to conservative measures. Nevertheless, several complications have been reported, including, among others, wound infection, vascular injury, retrograde ejaculation, postsympathectomy syndrome, ileus, and cerebrospinal fluid (CSF) leak. Although CSF leakage is rare, we discuss a case of CSF leakage and the diagnosis and management of CSF leakage after lumbar total disc replacement. Read More

Objective: Conflicting evidence exists to what extent manual material handling (MMH) causes lumbar disc disease, lack of evidence exist that this effect takes place especially at L5-S1 level, where the greatest moment occurs. The aim was to assess if lumbar vertebral body and disc changes are more common in people whose job involves significant MMH and, if so, to evaluate if lumbar vertebral body and disc changes are more prevalent in the lower part of the lumbar spine (L4-L5 and L5-S1).

Design: Observational, cross-sectional, with quasi-random recruitment. Read More

Background Context: Dural tear represents a common complication of microendoscopic spine surgery that may lead to postoperative sequelae including insufficient decompression, cerebrospinal fluid fistula, intracranial hypotension, and subdural/intraparenchymal bleeding. The gold standard to manage intraoperative dural tears is primary repair. However, the downside of conversion to open surgery can be detrimental. Read More

Whole-body vibration (WBV) has been identified as one of the serious risk factors leading to spinal disorders, particularly in professional drivers. Although the influential factors in this area have been investigated epidemiologically, finite element (FE) modeling can efficiently help us better understand the problem. In this study, a modified HYBRID III dummy FE model which was enhanced by detailed viscoelastic discs in the lumbar region was utilized to simulate the effect of WBV on lumbar spine loads. Read More

We describe the case of a 30-year-old patient who was referred for lumbar epidural corticosteroid injection due to right L5 radiculopathy. Two months earlier, MRI demonstrated a right large paracentral L4-L5 disk extrusion causing disabling L5 radiculopathy. The L4-L5 level was selected for interlaminar injection, using fluoroscopic guidance. Read More

Based on the long-term observation of 105 representatives of the elderly and senile age, the features of the clinical picture of pain syndromes formed in the elderly and senile age on the basis of combined spinal lesions in osteoporosis and spondylarthrosis are presented, and methods of diagnosis and treatment of such patients are proposed. The main variants of symptoms developing in response to long-term tonic muscle tension in degenerative age-dependent injuries of vertebral bodies, intervertebral discs and facet joints at the level of thoracic and lumbosacral spine are shown. Pathogenetic connections of frequent urination disorders in the elderly and senile age with pathological processes in the spine and muscular-tonic pain syndromes were determined. Read More

Surgical treatment for high-grade spondylolisthesis with high sacral slope remains controversial and no definitive gold standard procedure has been identified. The Bohlman technique, in which a fibular strut is reamed posteriorly across the L5-S1 disc space in an oblique, inferior to superior trajectory, has been increasingly utilized. Recently, a Reverse Bohlman technique has been described, in which a graft is reamed anteriorly across a single disc space in a superior to inferior trajectory. Read More

Mathematical models of the human spine can be used to investigate spinal biomechanics without the difficulties, limitations and ethical concerns associated with physical experimentation. Validation of such models is necessary to ensure the modeled system behavior accurately represents the physics of the actual system. The goal of this work was to validate a medical image-based nonlinear lumbosacral spine finite element model of a healthy 20-year-old female subject under physiological moments. Read More

Objective: Lumbar spondylolisthesis can be related to facet arthropathy and disc degeneration or to a fracture of the pars interarticularis, but the mechanistic underpinnings of spondylolisthesis remain unclear. We posit that high sacral slope and body weight increase sacral inclination vector forces, which leads to pars fractures and exacerbates risk for spondylolisthesis.

Methods: To investigate this hypothesis, we measured the sacral slope, body weight, and S1 endplate vector forces for patients who underwent L5-S1 fusion for grade I spondylolisthesis. Read More

One cat was presented for investigation of urinary retention and constipation and a second cat was presented with decreased appetite, reluctance to jump, reduced level of activity, and constipation. Magnetic resonance imaging revealed dorsal bulging of the hypo-intense intervertebral disc at S3-Cd1 on fast spin echo T2. Dorsal laminectomy was performed and both cats recovered with resolution of neurological signs. Read More
