STUDY DESIGN Prospective. OBJECTIVES The goal of this study was to evaluate the effect of posterior spinal fusion surgery terminating at different lowest instrumented vertebrae (LIV) on trunk mobility in individuals with adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA Posterior spinal fusion with instrumentation is the standard surgical technique employed in AIS for correc...
BACKGROUND CONTEXT Spinal implants are occasionally removed due to infection or soft tissue irritation secondary to prominence. Several studies have reported loss of scoliotic curve correction after implant removal. However, further review of the literature reveals no similar cases of rapid curve progression following implant removal in patients with adolescent idiopathic scoliosis (AIS) necess...
Spinal surgery, particularly spinal fusion surgery, alters the anatomy of the spine and hence, may increase the difficulty of performing an interventional spine procedure. Transforaminal epidural procedures have gained popularity as an alternative to interlaminar epidural steroids in the management of radicular pain syndromes. Patients with failed back surgery syndrome are often excluded or rep...
OBJECTIVE To explore the safety and efficacy of transpseudarthrosis osteotomy with interbody fusion in the treatment of Ankylosing Spondylitis (AS) patients with kyphotic spinal pseudarthrosis by a single posterior approach. METHODS Twelve consecutive patients with spinal pseudarthrosis underwent transpseudarthrosis osteotomy and interbody fusion with a polyetheretherketone (PEEK) cage by a s...
We report a case of a 66-year-old woman with progressing myelopathy. Her history revealed instrumented fusion from T10 to S1 for degenerative lumbar kyphosis and spinal stenosis. The plain radiographs showed narrowing of the intervertebral disc space with a gas shadow and sclerotic end-plate changes at T9-T10. Magnetic resonance imaging revealed a posterolateral mass compressing the spinal cord...
STUDY DESIGN A retrospective study. OBJECTIVE The purpose of this study was to identify the rates and reasons, and the risk factors for unplanned reoperation of lumbar spinal surgery during the primary admission in terms of a multicenter and a large patient population study. SUMMARY OF BACKGROUND DATA Unplanned reoperation is suggested to be a useful quality indicator for spinal surgery. Ho...
BACKGROUND This study was undertaken to assess the radiologic outcome of spinal fusion, with bone chips from laminectomy in patients with lumbar spondylolisthesis. METHODS From January 1993 to September 2001, 95 patients with lumbar spondylolisthesis were managed and followed up well at our Orthopedic Division. All patients presented with persistent low back pain, radiculopathy and claudicati...
OBJECTIVE Using alendronate after spinal fusion is a controversial issue due to the inhibition of osteoclast mediated bone resorption. In addition, there are an increasing number of reports that the endplate degeneration influences the lumbar spinal fusion. The object of this retrospective controlled study was to evaluate how the endplate degeneration and the bisphosphonate medication influence...
STUDY DESIGN Retrospective case series. PURPOSE The purpose of this study was to examine changes in the ligamentum flavum thickness and remodeling of the spinal canal after anterior fusion during a 10-year follow-up. OVERVIEW OF LITERATURE Extreme lateral interbody fusion provides minimally invasive treatment of the lumbar spine; this anterior fusion without direct posterior decompression, ...
Posterior atlantoaxial dislocation without odontoid fracture is extremely rare and often results in fatal spinal cord injury. According to the reported literature, all cases presented mild or no neurologic deficit, with no definite relation to upper spinal cord injury. Little is reported about traumatic posterior atlantoaxial dislocation, with incomplete quadriplegia associated with a spinal co...
