Conditions

Lumbar Spinal Stenosis

Brief summary

The purpose of this study was to compare standard open laminectomy with ULBD approach in regard to efficiency, safety, and clinical outcome.

Detailed description

Lumbar stenosis is one of the common spinal pathologies; it presents with back pain, leg pain, and neurogenic claudication . Although different surgical modalities are available, the main objective of the operation is decompression of nerve roots and the spinal cord. Minimally invasive surgical procedures and microsurgical unilateral laminotomy with bilateral spinal canal decompression (ULBD) have been reported to achieve this goal . The objective of lumbar decompression is to decompress the neural elements while preserving stability and the spinous processes. The object of this study is to compare outcomes following minimally invasive unilateral laminectomy for bilateral decompression (ULBD) to a standard open laminectomy for LSS.
