We present a case of an acute psoas muscle hematoma following percutaneous endoscopic lumbar discectomy. A 60-year-old female who presented with far lateral lumbar disc herniation underwent endoscopic discectomy on the right side at the L4-5 level. On the second postoperative day, the patient complained of severe right flank and leg pain and her blood pressure decreased. A computed tomography s...

Lumbar microdiscectomy, which relies on the operating microscope for visualization, was first described in the late 1970s. This operation is considered the gold standard procedure for patients who require surgery for symptomatic lumbar disc herniation causing radiculopathy that has not improved with conservative measures. A new approach to the management of symptomatic lumbar disc herniation, m...

BACKGROUND Biomechanical studies have shown that dynamic stabilization restores the neutral zone and stabilizes the motion segment. Unfortunately, there are limitations to clinical measurement of lumbar motion segments when using routine radiographs. Radiostereometric analysis is a 3-dimensional technique and can measure the spinal motion segment more accurately than techniques using plain film...

OBJECTIVE We evaluated postoperative outcomes in patients who have lumbar foraminal or extraforaminal disc herniation (FELDH) and suggested the risk factors for poor outcomes. METHODS A total of 234 patients were selected for this study. Pre- and post-operative Visual Analogue Scale (VAS) and Korean version Oswestry Disability Index (KODI) were evaluated and the changes of both score were cal...

Low back pain is common during pregnancy. However, the prevalence of symtomatic lumbar disc herniation is rare, and cauda equina syndrome due to disc herniation during pregnancy is even rarer. We report a rare case of lumbar disc herniation causing cauda equina syndrome during third trimester of pregnancy which successfully treated by endoscopic discectomy. This case shows that endoscopic disce...

STUDY DESIGN Systematic review and meta-analysis of comparative studies. OBJECTIVE To characterize the association of annular defect width after lumbar discectomy with the risk of symptom recurrence and reoperation. SUMMARY OF BACKGROUND DATA Large annular defect width after lumbar discectomy has been reported to increase risk of symptom recurrence. However, this association has not been ev...

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...

Background Data: Recurrence of LDH has been reported in 5%–11% patients after conventional discectomy, and most these are usually treated with repeated discectomy through the same initial approach. Tubular microdiscectomy is an increasingly popular surgery for lumbar disc prolapse replaced open last decade. However, it requires more experience a steep learning curve, especially revision cases.

BACKGROUND Percutaneous endoscopic lumbar discectomy is a relatively new technique. Very few studies have reported the clinical outcome of percutaneous endoscopic discectomy in terms of quality of life and return to work. METHOD 55 patients with percutaneous endoscopic lumbar discectomy done from 2002 to 2006 had their clinical outcomes reviewed in terms of the North American Spine Score (NAS...
