Degeneration of the lumbar intervertebral discs is a leading cause of chronic low back pain in adults. Treatment options for patients with chronic lumbar discogenic pain unresponsive to conservative management include total disc replacement (TDR) or lumbar fusion. Until recently, only two lumbar TDRs had been approved by the US Food and Drug Administration - the Charité Artificial Disc in 2004 ...

SUMMARY OF BACKGROUND DATA The association between the facet tropism and the development of lumbar disc herniation has been studied; however the results remain controversial. OBJECTIVE To determine the association between the facet tropism and the development of lumbar disc herniation. STUDY DESIGN A cross-sectional study. MATERIAL AND METHOD MRI of 34 patients with lumbar disc herniation...

Introduction: Disc degeneration is a natural aging process characterized by changes in appearance and chemical structure of the disc. This degeneration leads to back pain. In regard to the limitation of current therapeutical methods for patients with degenerated discs, arthroplasty has been suggested as an alternative method. To manufacture artificial discs for Iranians, determining normal lumb...

Lumbar radiculopathy is generally caused by such well-recognized entity as lumbar disc herniation in neurosurgical practice; however rare pathologies such as thrombosed epidural varix may mimic them by causing radicular symptoms. In this case report, we present a 26-year-old man with the complaint of back and right leg pain who was operated for right L4-5 disc herniation. The lesion interpreted...

OBJECTIVES Many studies have investigated the kinematics of the lumbar spine and the morphological features of the lumbar discs. However, the segment-dependent immediate changes of the lumbar intervertebral space height during flexion-extension motion are still unclear. This study examined the changes of intervertebral space height during flexion-extension motion of lumbar specimens. METHODS ...

Background and Importance: Intradural lumbar disc herniation is a rare and uncommon presentation of lumbar disc herniation. It signifies a challenge for diagnostic and therapeutic scheme, and is associated with a greater incidence of cauda equina syndrome at presentation. Case Presentation: We describe two cases of intradural disc herniation who underwent surgery in Senegal review literat...

BACKGROUND There is a controversy regarding the treatment of lumbar disc herniation. Most of patients with lumbar disc herniation and radiculopathy improve with rest and medicine. Lumbar disc surgery gives rapid relief to the patients with severe root pain in legs. This study was conducted to see the risks and benefits of surgery in single level symptomatic lumbar disc disease. METHODS This p...

in this study to determine whether spine stiffness is predictive of clinical results after lumbar spinal fusion for spinal stenosis, a total of 78 patients were measured intraoperatively with kocher clamp manual distraction technique to determine motion segment stiffness then spinal fusion was performed for any loose segment. ‎statistical analysis revealed that stiffness measurement correlate w...

BACKGROUND Low back pain with or without lower extremity pain is the most common problem among chronic pain disorders with significant economic, social, and health impact. This study was conducted to determine the frequency of lumbar disc herniation and its different levels, among patients with chronic backache. METHODS This cross sectional study was conducted in the department of Neurosurger...

Microsurgery for lumbar herniated discs that require surgical intervention is a very successful and well-described technique, whether performed through more traditional "open" microsurgical retractors or through minimally-invasive "tube" retractors. Surgery for extruded lumbar disc fragments that migrate caudad or cephalad from the disc origin may typically require modifying the standard hemila...
