BACKGROUND: Lumbar facet cysts are a benign, degenerative, and fairly uncommon cause for lumbar radiculopathy. The standard surgical treatment for lumbar facet cysts often requires a laminectomy and medial facetectomy which can further destabilize a pathological motion segment. The authors present here a novel technique for transpedicular endoscopic access to the pathology that obviates the need to violate the lamina or facet. METHODS: Two patient cases are described where the lumbar 4-5 facet cysts arise medial to the pedicle...

BACKGROUND: Lumbar microdiscectomy and laminectomy are two of the most common neurosurgical procedures performed worldwide. Current practice still sees pre-operative group and save testing prior to this surgery. The aim of this study was to determine the need for pre-operative group and save and post-operative blood checks. METHODS: Patient archives were reviewed to identify those undergoing primary elective lumbar decompression surgery at the Institute of Neurological Sciences, Queen Elizabeth University Hospital, Glasgow, UK...

Lumbar laminectomy is one of the most common treatments for lumbar disc herniation and other lumbar disorders with serious complications, such as failed back surgery syndrome, mainly caused by epidural fibrosis (EF). The developing fibrosis causes radicular pain after the laminectomy or discectomy. Methotrexate (MTX) is a folic acid antagonist that has shown anti-proliferative effects in previous studies. The aim of our experiment is to study whether MTX has positive effects on the outcome of the laminectomy in rats...

OBJECTIVE: Spinal subdural hematomas (SSDHs) are rare. Causes are (1) posttraumatic, (2) iatrogenic (following surgery or lumbar puncture), (3) spontaneous including underlying malformations or coagulation deficits. With a systematic review of literature we want to shed light on the last group: symptomatology, etiology, treatment and outcome will we discussed. METHODS: Systematic review of literature on PubMed for cases of acute nontraumatic noniatrogenic SSDHs in adults (≥18 y of age)...

Introduction Posterior midline laminectomy is associated with risks of postoperative instability, spinal deformity, extensive bilateral subperiosteal muscle stripping, partial or total facetectomy especially in foraminal tumor extension, increased cerebrospinal fluid leakage, and wound infection. Minimally invasive approaches with the help of a microscope or endoscope using hemilaminectomy have been found to be safe and effective. We report our initial experience of 18 patients using the endoscopic technique...

OBJECTIVE: Spinal cord injury (SCI) is a devastating neurological trauma with a prevalence of about 282 000 people living with an SCI in the United States in 2016. Advances in neuromodulatory devices hold promise for restoring function by incorporating the delivery of electrical current directly into the spinal cord grey matter via intraspinal microstimulation (ISMS). In such designs, detailed topographic maps of spinal cord outputs are needed to determine ISMS locations for eliciting hindlimb movements...

OBJECTIVE: To investigate the biomechanical effects of the lumbar posterior complex on the adjacent segments after posterior lumbar interbody fusion (PLIF) surgeries. METHODS: A finite element model of the L1-S1 segment was modified to simulate PLIF with total laminectomy (PLIF-LAM) and PLIF with hemilaminectomy (PLIF-HEMI) procedures. The models were subjected to a 400N follower load with a 7.5-N.m moment of flexion, extension, torsion, and lateral bending. The range of motion (ROM), intradiscal pressure (IDP), and ligament force were compared...

BACKGROUND: Symptomatic lumbar spinal stenosis (LSS) is the most common reason for lumbar surgery in the elderly. There is growing evidence that decompressive surgery offers an advantage over non-surgical management for selected patients with persistent severe symptoms. Based on treatment traditions, open laminectomy has been the gold standard surgical treatment, but various other surgical and non-surgical treatments for LSS are widely used in clinical practice. Therefore, we conducted a survey study to capture potential diversities in surgeons' management of LSS in Norway...

Interspinous process decompression is a minimally invasive implantation procedure employing a stand-alone interspinous spacer that functions as an extension blocker to prevent compression of neural elements without direct surgical removal of tissue adjacent to the nerves. The Superion® spacer is the only FDA approved stand-alone device available in the US. It is also the only spacer approved by the CMS to be implanted in an ambulatory surgery center. We computed the within-group effect sizes from the Superion IDE trial and compared them to results extrapolated from two randomized trials of decompressive laminectomy...

Lumbar intraspinal synovial cysts are included in the difference diagnosis of lumbar radiculopathy. Developing imaging modalities has result in increased reporting about these lesions. However, the case of bilateral new lumbar intraspinal synovial cysts after laminectomy has been rarely reported. We report of a rare case with bilateral lumbar intraspinal synovial cysts after laminectomy, requiring surgical excision.
