Endoscopic decompression for intraforaminal and extraforaminal nerve root compression
OBJECTIVE The purpose of this study was to evaluate the outcome of endoscopic decompression surgery for intraforaminal and extraforaminal nerve root compression in the lumbar spine. METHODS The records from seventeen consecutive patients treated with endoscopic posterior decompression without fusion for intaforaminal and extraforaminal nerve root compression in the lumbar spine (7 males and 1...
متن کاملSpinal nerve root compositions of musculocutaneous nerve: an anatomical study.
AIM This study was aimed to investigate the variations in the spinal nerve root compositions of musculocutaneous nerve and to confirm which spinal nerve root is the main ingredient in participating amount. MATERIAL AND METHODS A total of 20 fresh cadavers were dissected. Brachial plexus and its branches were extracted. Musculocutaneous nerve stump was traced back to the roots to identify its ...
متن کاملA Biomechanical Stability Study of Extraforaminal Lumbar Interbody Fusion on the Cadaveric Lumbar Spine Specimens
BACKGROUND Transforaminal lumbar interbody fusion (TLIF) is an effective surgery for lumbar degenerative disease. However, this fusion technique requires resection of inferior facet joint to provide access for superior facet joint resection, which results in reduced lumbar spinal stability and unnecessary trauma. We have previously developed extraforaminal lumbar interbody fusion (ELIF) that ca...
متن کاملNavigated Transtubular Extraforaminal Decompression of the L5 Nerve Root at the Lumbosacral Junction: Clinical Data, Radiographic Features, and Outcome Analysis
Purpose. Extraforaminal decompression of the L5 nerve root remains a challenge due to anatomic constraints, severe level-degeneration, and variable anatomy. The purpose of this study is to introduce the use of navigation for transmuscular transtubular decompression at the L5/S1 level and report on radiological features and clinical outcome. Methods. Ten patients who underwent a navigation-assis...
متن کاملIsolated Lumbar Spinal Nerve Root Myxopapillary Ependymoma
Myxopapillary ependymomas comprise nearly 90% of all primary neoplasms involving the cauda equina, conus medullaris, and filum terminale. Myxopapillary ependymomas that are confined to nerve roots are exceedingly rare. We describe a young patient who presented with low back pain and radiculopathy and an intradural lesion at the L2 vertebral level. Ultimately, an intradural extramedullary tumor ...
