Barrington's nucleus (Bar) is thought to contain neurons that trigger voiding and thereby function as the "pontine micturition center." Lacking detailed information on this region in mice, we examined gene and protein markers to characterize Bar and the neurons surrounding it. Like rats and cats, mice have an ovoid core of medium-sized Bar neurons located medial to the locus coeruleus (LC). Bar neurons express a GFP reporter for Vglut2, develop from a Math1/Atoh1 lineage, and exhibit immunoreactivity for NeuN...

Pudendal neuralgia (PN) is a result of pudendal nerve entrapment or injury, also called "Alcock syndrome." Pain that develops is often chronic, and at times debilitating. If conservative measures fail, invasive treatment modalities can be considered. The goal of this case report is to add to a small body of literature that a pulsed radiofrequency (PRF) ablation can be effectively used to treat PN and to show that high resolution MR neurography imaging can be used to detect pudendal neuropathy. CASE PRESENTATION: We present a case of a 51-year-old woman with 5 years of worsening right groin and vulva pain...

PROBLEM AND HYPOTHESIS: Over time, some patients with unilateral or bilateral lumbosacral injuries experience chronic low back pain. We studied the sagittal and frontal balance in a population with these injuries to determine whether mismatch in the pelvic and lumbar angles are associated with chronic low back pain. PATIENTS AND METHODS: Patients with posterior pelvic ring fractures (Tile C1, C2, C3 and A3.3) that had healed were included. Foreign patients and those with an associated spinal or acetabular fracture or nonunion were excluded...

REVIEW
Hiroshi Takasaki, Takahiro Miki
BACKGROUND CONTEXT: The lumbosacral orthosis (LSO) is prescribed by general practitioners for the management of low back pain. It may be speculated that continuous use of the LSO for a prolonged period reduces mechanical loading to the trunk muscle in daily living and results in impairments of the trunk muscle. PURPOSE: To investigate whether the trunk motor performances are impaired by continuous use of the lumbosacral orthosis. STUDY DESIGN/SETTING: Systematic review with meta-analysis...

BACKGROUND CONTEXT: Surgical treatment of symptomatic adjacent segment disease (ASD) typically involves extension of previous instrumentation to include the newly-affected level(s). Disruption of the incision-site can present challenges and increases the risk of complication. Lateral-based interbody fusion techniques may provide a viable surgical alternative that avoids these risks. This study is the first to analyze the biomechanical effect of adding a lateral-based construct to an existing fusion...

Doniel Drazin, Ari Kappel, Stefan Withrow, Tiffany Perry, Ray Chu, Surasak Phuphanich
BACKGROUND: Multiple radiation-induced cavernous malformations of the cauda equina are extremely rare. A review of the literature suggested that the post-irradiation lumbosacral radiculopathy in our patient was most likely associated with a diagnosis of multiple radiation-induced cavernous malformations of the cauda equina. CASE DESCRIPTION: A 76-year-old man with a remote history of abdominal radiation therapy presented with a 6-month history of progressively worsening right foot drop and balance impairment...

Positively-charged oligo[poly(ethylene glycol)fumarate] (OPF(+) ) is a biodegradable hydrogel used for spinal cord injury repair. We compared scaffolds containing primary Schwann cells (SCs) to scaffolds delivering SCs genetically modified to secrete high concentrations of glial cell-derived neurotrophic factor (GDNF). Multichannel OPF(+) scaffolds loaded with SCs or GDNF-SCs were implanted into transected rat spinal cords for 4 weeks. GDNF-SCs promoted regeneration of more axons into OPF(+) scaffolds (2773...

INTRODUCTION: In reviewing a larger group of osteoporotic vertebral compression fractures (VCFs), we found that the overall incidence of sacral insufficiency fractures (SIFs) is higher than commonly reported values. This is especially seen in patients with previous or concurrent lumbar VCFs and also in a subgroup that had lumbar stenosis or hip arthroplasty. The altered biomechanics due to associated lumbar stenosis or hip arthroplasty lead to increased mechanical stress on already weakened and deficient sacral alae, which are more vulnerable to osteoporotic weakening than other parts of the sacrum...

OBJECTIVE There has been no established animal model of syringomyelia associated with lumbosacral spinal lipoma. The research on the pathophysiology of syringomyelia has been focused on Chiari malformation, trauma, and inflammation. To understand the pathophysiology of syringomyelia associated with occult spinal dysraphism, a novel animal model of syringomyelia induced by chronic mechanical compression of the lumbar spinal cord was created. METHODS The model was made by epidural injection of highly concentrated paste-like kaolin solution through windows created by partial laminectomy of L-1 and L-5 vertebrae...

Bertolotti syndrome is a form of low-back pain associated with lumbosacral transitional vertebrae. We report a case of a 34-year-old woman with breast cancer presented with severe low-back pain. F-NaF PET/CT demonstrates increased radiotracer uptake at the transverse-sacral articulation corresponding to hemisacralized left transverse process of L5 vertebra. Increased tracer uptake in patients with lumbosacral transitional vertebrae seems to correlate with lower-back pain symptoms. F-NaF PET/CT can be useful in evaluation of some uncommon causes of low-back pain...

An 8-year-old girl presented with back and leg pain and left arm and leg paresis. Lumbar puncture was suggestive of lymphocytic meningitis without identified organism. A second lumbar puncture demonstrated a large number of lymphoid B cells, with positive immunohistochemical staining for CD20 and CD25, proving the diagnosis of neurolymphomatosis. Brain and spine MRI demonstrated involvement of cervical and lumbosacral nerve roots. FDG PET/CT showed multiple bone metastases in addition to nerve involvement. Postchemotherapy FDG PET/CT demonstrated complete metabolic response...

Cauda equina syndrome is a serious condition resulting from dysfunction of the lumbosacral nerve roots and characterized by impairment of bladder, bowel, sexual and lower limb functions. We report the case of a 48-year-old woman who had Crohn's disease for more than twenty years. The patient was undergoing immunotherapy with infliximab and developed a partial cauda equina syndrome after an uneventful minimally invasive microdiscectomy (L5-S1) that completely cured her sciatica. A postoperative magnetic resonance imaging examination showed root clumping but no compressive lesion...

BACKGROUND: With the concept of the hybrid operating room gaining popularity, the authors adapted a hybrid angiographic suite with intraoperative computed tomography (iCT) to evaluate accuracy of pedicle screw placement in spinal fusion. This retrospective review examines how well iCT detected extrapedicular screw violation, to then allow repositioning and potentially avoid revision surgery. METHODS: A total of 36 consecutive patients underwent pedicle screw placement in posterior cervical, thoracic, and lumbosacral spinal fusions...

BACKGROUND DATA: Combined usage of posterior lumbar interbody fusion and transpedicular fixation has been extensively used to treat the various lumbar degenerative disc diseases. The transpedicular fixator aims to increase stability and enhance the fusion rate. However, how the fused disc and bridged vertebrae respectively affect adjacent-segment diseases progression is not yet clear. METHODS: Using a validated lumbosacral finite-element model, three variations at the L4-L5 segment were analyzed: 1) moderate disc degeneration, 2) instrumented with a stand-alone cage and pedicle screw fixators, and 3) with the cage only after fusion...

OBJECTIVE: A method applying inertial measurement units (IMUs) was developed to implant pedicle screws in the thoracic and lumbosacral spine. This was compared with a freehand technique. METHODS: The study was done on 9 human cadavers. For each cadaver, a preoperative computed tomography (CT) scan was performed to measure the axial and sagittal tilt angles of the screw trajectories from T1 to S1. After the entry points were defined on the exposed spine, the IMU-equipped pedicle finder and screwdriver were used to reproduce these tilt angles and implant half of the screws...
