BACKGROUND The use of pedicle screws is the gold standard for supplemental posterior fixation in lateral interbody fusion. Information about the performance of transfacet pedicle screws compared to standard pedicle screws and rods in the upper lumbar spine with or without a lateral interbody fusion device in place is limited. METHODS Fifteen fresh frozen human cadaveric lumbar spine segments ...

Paraspinal muscles are commonly affected during spine surgery. The purpose of this study was to assess the potential factors that contribute to paraspinal muscle atrophy (PMA) after lumbar spine surgery. A comprehensive review of the available English literature, including relevant abstracts and references of articles selected for review, was conducted to identify studies that reported PMA afte...

Traumatic spondylolisthesis of the lumbar spine is uncommon and can result in canal narrowing and spinal cord injury. Early decompression promotes recovery of neurological function. We report 3 such cases: one in the lumbosacral joint and 2 in the lumbar spine. The former patient had an open fracture-dislocation and underwent (delayed) posterior decompression and instrumentation without interbo...

BACKGROUND Increased awareness regarding the importance of the sagittal spinal profile has led to more aggressive correction of sagittal malalignment. The utilization trends of pedicle subtraction osteotomy (PSO) for sagittal plane correction in spinal deformity surgery have not been well characterized. METHODS A commercially available database (PearlDiver, Inc) was queried for both Private P...

UNLABELLED Surgery on the degenerative cervical spine disorders aims at decompression of the neural structures and restoring the physiological profile of the cervical spine. The aims of internal fixation are to gain primary stability, introduce a bony fusion and to correct the shape of the spine. The present study will give answers to the following questions: 1. What is the overall revision rat...

BACKGROUND While there are variations in techniques and surgical approaches to spinal fusion, there is not a defined consensus on a recommended surgical approach. The aim of this study is to determine if there was a difference in intra- and post-operative complication rates between different surgical approaches after elective spinal fusion (≥3 levels) for adult spine deformity. METHODS The me...

Dialysis-related spondyloarthropathy is a rare cause of spinal deformity and cervical myelopathy. Optimal management of cervical spine spondyloarthropathy often requires circumferential reconstructive surgery, because affected patients typically have both the anterior column and the facet joints compromised. The occasional presence of noncontiguous or "skip lesions" adds an additional level of ...

STUDY DESIGN This technique article describes accomplishing multilevel posterior cervical decompression and lateral mass screw placement through a tubular retraction system. OBJECTIVE Multilevel foraminotomy and instrumented fusion using lateral mass screw fixation can be achieved through a minimally invasive technique using specialized retractors and intraoperative fluoroscopic imaging.
