Minimal Invasive Surgery Versus Interlaminar Decompression in Lumbar Canal Stenosis

Lumbar Spinal Stenosis Clinical Trial

Official title:
Minimally Invasive Surgery Versus Conventional Open Interlaminar Decompression in Treatment of Degenerative Lumbar Canal Stenosis

Clinical Trial Summary

Conventional open surgery has been shown to be an effective procedure for LCS decompression. Minimally invasive surgery (MIS) through tubular retractors is a recently introduced alternative procedure for decompression of LCS. The current study aims at evaluating the efficacy of minimally invasive surgery as a decompressive procedure in comparison to conventional open surgery for the treatment of patients with LCS.

Clinical Trial Description

Lumbar canal stenosis (LCS) is defined as narrowing of the spinal canal, the vertebral foramina, and/or the lateral recesses, causing compression on the nearby neurologic structures. Degenerative LCS is one of the most common reasons for old patients to undergo spinal surgery. Neurogenic claudication is the most common symptom for LCS patients. The patients complain of pain or discomfort that radiates to the buttock, thigh and lower limb after walking for a certain distance, therefore leading to functional disability and decreased walking capacity. Conservative management is the first line of treatment in the absence of progressive neurologic deficit or intractable pain, consisting of physical therapy, medications (analgesics, steroids) and pain management procedures. Surgical intervention is recommended if the symptoms are persistent or worsening. Various techniques are currently used for direct decompression of LCS. Conventional open surgery involves laminectomy that has been shown to be an effective procedure for LCS decompression. However, wide laminectomies disturbs the stability of bony and ligamentous structures and may exacerbate preexisting spondylolisthesis. Minimally invasive surgery (MIS) through tubular retractors is a recently introduced alternative procedure for decompression of LCS. This technique avoids detachment of the paraspinal muscles and may promote preservation of stabilizing ligamentous and bony spinal structures. The current study aims at evaluating the efficacy of minimally invasive surgery as a decompressive procedure in comparison to conventional open surgery for the treatment of patients with LCS. ;
