BACKGROUND Lumbar disc prolapse is a common problem and the current surgical standard for its treatment is a microsurgical discectomy. Microendoscopic discectomy (MED) is a minimally invasive spinal procedure being done successfully for prolapsed intervertebral disc disease. AIMS We report the technique, outcome and complications seen in 107 cases of prolapsed lumbar intervertebral disc who u...

The purpose of this study was to determine whether the anatomic position of a lumbar disc herniation has any significant effect on the clinical outcome of lumbar discectomy. Between January 1988 and March 1993, 80 patients with simple disc herniations underwent lumbar discectomy for herniated nucleus pulposus. We reviewed preoperative computed tomography scans after discography and magnetic res...

STUDY DESIGN A case report. OBJECTIVE To demonstrate a case of intradural lumbar disc herniation including imaging studies, intraoperative imaging, and an intraoperative video. SUMMARY OF BACKGROUND DATA The first case of lumbar intradural disc herniation was reported as early as 1942; since then more than 150 cases have been reported, mostly in the lumbar spine. Gadolinium-enhanced magneti...

BACKGROUND Since the descriptions by Mixter and Barr of surgical treatment for rupture of the intervertebral disc in 1934, open surgical procedures have become a common practice. Disc herniations are often classified as being contained or non-contained. The results of open surgical discectomy for contained disc herniation have been poor. Consequently, several less invasive techniques have been ...

  Even though intervertebral disc degeneration can be found in the natural course of alkaptonuria, detection of the disease by black disc color change in a patient without any other presentation of alkaptonuria is an exceptionally rare condition. We have reported a very rare case of alkaptonuria presented with low back pain and steppage gait in a 51-year-old male with a complaint of chronic low...

The development in technology and informatics in the last decades enables integrated analysis of biomechanical and clinical data and facilitates the understanding of relations between human gait characteristic and different medical conditions of a patient. The aim of the study was to demonstrate the importance of gait temporospatial parameters analysis [opposite foot off, opposite foot contact,...

UNLABELLED The technique of percutaneous endoscopic lumbar discetomy (PELD) in the transforaminal approach has evolved over the years due to the advances in endoscopic photology and instrumentation and become the most popular technique for lumbar disc herniation. Although PELD offers many advantages, the indications of PELD are limited mostly to non-migrated or low-migrated disc herniation. It ...

An alternative approach to lumbar fusion surgery is to restore motion to the diseased segment with a disc prosthesis. The goal of the disc prosthesis is to replace the diseased disc while preserving and/or restoring the motion at the operated spinal level. The purpose of this study was to determine the ability of the PRODISC® (Spine Solutions Inc., Paoli, PA) disc prosthesis to restore lumbar s...

STUDY DESIGN Biomechanical in vitro study. OBJECTIVE To establish a reliable in vitro herniation model with human cadaver spines that enables evaluation of anular closure devices. SUMMARY OF BACKGROUND DATA Biomechanically, it is desirable to close anulus defects after disc herniation to preserve as much nucleus as possible. Multiple anular closure options exist to prevent reherniation. A r...
