MRI Findings in Extraforaminal Region of L5 Nerve.

Minimally Invasive Approach For Extraforaminal Synovial Cyst L5-S1.

Symptoms from synovial cysts are produced by neural compression in the spinal canal or the foramen. Few cases of extraforaminal synovial cyst have been published in the literature. This is a case report of a 65-year-old female who presented with a three-month history of sciatic pain and no relief with conservative treatment. MRI showed a left-sided extraforaminal synovial cyst at L5-S1 with com...

Reliability of MRI findings for Symptomatic Extraforaminal Disc Herniation in Lumbar Spine

STUDY DESIGN A retrospective study PURPOSE This study examined the reliability of the MRI findings in detecting symptomatic extraforaminal disc herniation in the lumbar spine. OVERVIEW OF LITERATURE There are no reports of the characteristics and reliable MRI findings of extraforaminal disc herniation. METHODS Thirty age-and gender-matched asymptomatic volunteers and 30 patients with symp...

Navigated 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...

Microsurgical 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...
