带蒂椎板成形术的设计与临床应用

Design and Clinical Application of Vertebral Canal Plasty Using Pedicelar Vertebral Lamina

目的 :探讨带蒂椎板成形术重建胸腰椎后部结构的临床效果。方法 :胸腰椎管狭窄患者 5 6例 ,均施行带蒂胸腰椎板成形术。结果 :术后经过 1～ 5年随访 ,4 7例 (83 9% )患者临床症状完全或大部消失 ,成形椎板愈合良好 ,椎管完整 ,9例 (16 1% )完全截瘫。结论 :带蒂椎板成形术符合脊柱的解剖生物特性 ,可替代现行的椎板切除术。

Objective: To discuss the clinical effect of reconstruction of posterior structure of the thoracic and lumbar vertebra by means of vertebral canal plasty with pedicelar vertebral lamina: Methods: 56 patients with thoracic and lumbar vertebral canal stricture were subjected to vertebral canal plasty with pedicelar vertebral lamina after posterior vertebral lamina ablate. Results: During a follow-up of 1 to 5 years, 9 patients (16.1 %) were paraplegic, and the remaining 47 (83.9 %) showed disappearance of clinical symptoms partially or completely. Meanwhile the vertebral lamina coalesced well and the vertebral canals were integrated as a result. Conclusion: Vertebral canal plasty with pedicelar vertebral lamina is compatible with spine's anatomic characteristics and is qualified to replace current vertebral lamina ablation.
