Neurogenic claudication was first related to lumbar stenosis (Verbiest H, 1954). Since, decompressive surgery was indicated in patients who failed to respond to conservative therapy. It is followed by posterior fusion in cases where the motion segment showed instability or in case where a secondary instability is expected to develop after surgery. However, while many patients have benefited fro...

BACKGROUND To evaluate the effect of spondylolisthesis on lumbar lordosis on the OSI (Jackson; Orthopaedic Systems Inc.) frame. Restoration of lumbar lordosis is important for maintaining sagittal balance. Physiologic lumbar lordosis has to be gained by intraoperative prone positioning with a hip extension and posterior instrumentation technique. There are some debates about changing lumbar lor...

In the treatment of multilevel degenerative disorders of the lumbar spine, spondylodesis plays a controversial role. Most patients can be treated conservatively with success. Multilevel lumbar fusion with instrumentation is associated with severe complications like failed back surgery syndrome, implant failure, and adjacent segment disease (ASD). This retrospective study examines the records of...

Study Design: Retrospective, single center, non-randomized study. Objectives: To evaluate the efficacy of Integra Collagen Ceramic Matrix (Collagen / β-TCP Composite) bone void filler in posterolateral lumbar fusions. Methods: All patients treated with Integra Collagen Ceramic Matrix (CCM) putty and/or strip during posterior or transforaminal lumbar fusion surgery between April 2007 – December ...

STUDY DESIGN Retrospective review of an administrative database. OBJECTIVE To observe New York statewide trends in lumbar spine surgery and to compare utilization of fusion according to hospital size and patient population. SUMMARY OF BACKGROUND DATA Over the last 30 years, studies have indicated increasing rates of spinal fusion procedures performed each year in the United States. There is...

Longer spinal fusions have been shown to result in improved deformity correction; however, loss of normal flexibility in the fusion area should not be ignored. Current consensus was to achieve a shorter fusion in primary surgery, with the goal of preserving as much of the distal motion segment as possible. However, the correlation between the length of fusion and functional outcome remains cont...

This video shows a minimally invasive technique for spine exposure anterior lumbar interbody fusion of L5-S1. The multidisciplinary team with the vascular surgery, urology, and neurosurgery was involved in this novel technique. eyJraWQiOiI4ZjUxYWNhY2IzYjhiNjNlNzFlYmIzYWFmYTU5NmZmYyIsImFsZyI6IlJTMjU2In0.eyJzdWIiOiIzOWIyZWEwMDJiZmYxMzQ3ZWM2ZjVmOTJmMDgwODRjOSIsImtpZCI6IjhmNTFhY2FjYjNiOGI2M2U3MWViY...
