Distraction laminoplasty is a technical modification of routine laminectomy that allows decompression of the lumbar spinal canal with maximal bone preservation. The technique involves the application of a distraction force, in conjunction with an undercutting laminoplasty technique. It is safe, easily applied, and allows excellent canal visualization and decompression with minimal bone resection. The purpose of the current study is to describe the technical aspects of the technique.
撑开式椎板成形术是常规椎板切除术的一种技术改良，可在最大限度保留骨质的情况下实现腰椎管减压。该技术包括施加撑开力，并结合潜行椎板成形术。它安全、易于实施，能在最小程度的骨质切除下实现极佳的椎管视野和减压效果。本研究的目的是描述该技术的技术要点。
