Improved percutaneous endoscopic translaminar approach for lumbar foraminal stenosis at L5/S1
The operative approach for lumbar foraminal stenosis (LFS) is one of the most challenging for spinal surgeons.[1-3] Excessive removal of the dorsal area of the foramen in a posterior approach can easily lead to iatrogenic spondylolysis, subsequently increasing lumbar instability and spondylolisthesis. A posterolateral approach is one solution to this problem. However, LFS in the L5/S1 region is...
متن کاملUsefulness of Three Dimensional Proset MR Images for Diagnosis of Symptomatic L5-S1 Foraminal and Extraforaminal Stenosis
OBJECTIVE To suggest a new useful diagnostic technique, principles of the selective excitation technique-magnetic resonance images (Proset-MRI), and to know the precise radiologic findings that can prove symptomatic foraminal and extraforaminal stenosis at L5-S1. METHODS Nineteen patients with symptomatic L5-S1 stenosis were checked by Proset-MRI. Four patients were performed decompressive su...
متن کاملSuprapedicular Foraminal Endoscopic Approach to Lumbar Lateral Recess Decompression Surgery to Treat Degenerative Lumbar Spinal Stenosis
BACKGROUND To discuss the strategy of suprapedicular foraminal endoscopic approach to lumbar lateral recess decompression and evaluate the safety and effectiveness of this strategy. MATERIAL AND METHODS Complete clinical information of 52 cases of lumbar lateral recess decompression with therapy of suprapedicular foraminal endoscopic approach were analyzed during the period from February 2010 t...
متن کاملPercutaneous Endoscopic Lumbar discectomy for Foraminal to Superior Migrated Disc at L5- S1 level using the Contralateral Interlaminar Approach: A Technical Case Report
Objective: In cases of foraminal superior migration of L5-S1 HNP, it is very difficult to access by rigid endoscopic procedure. Thus, we attempted a contralateral interlaminar approach to expose the exiting nerve root and contralateral foramen to remove the symptomatic disc and preserve the functional structures. Methods: Between January 2013 and January 2014, five patients who received the per...
متن کاملMicrosurgical midline approach for the decompression of extraforaminal stenosis in L5-S1.
OBJECT When performing surgery, the extraforaminal window is very narrow at the L5-S1 level. The authors describe a microsurgical method for decompression of the L-5 nerve root trapped between a marginal osteophyte of the vertebral body and the transverse process. The procedure was performed in 16 patients with extraforaminal stenosis. METHODS The cranial part of the L5-S1 facet joint and the...
