Selective decompression and translaminar articular facet screw fixation for lumbar canal stenosis and disc protrusion

Abstract

A technique is described for lumbar canal stenosis and disc protrusion combining safe and selective decompression and translaminar screw fixation. After experience with 166 cases from 1987 to 1991 we consider this technique particularly suitable for the treatment of lumbar spinal stenosis and also for the few cases of lumbar disc displacement which need a primary fusion.

Key Words:

• Lumbar canal stenosis
• posterior lumbar fusion
• translaminar screw fixation
• lumbar instability
• lumbar disc protrusion
