laminoplasty
Surgical technique that expands the spinal canal by creating a hinged opening in the lamina rather than complete removal.
Full Definition
A motion-preserving spine surgery technique used primarily in the cervical region to decompress the spinal cord while maintaining posterior spinal elements. The procedure involves creating a hinge on one side of the lamina and opening it like a door, then securing it in the open position with plates or spacers. This approach preserves more anatomy than laminectomy while providing adequate decompression for conditions like cervical stenosis or ossification of the posterior longitudinal ligament.
Usage
Usage note: Distinguish from laminectomy (removal) and laminotomy (small opening). Often modified with 'cervical' or technique type.
