摘要
【目的】从临床角度探讨孤立型胸椎黄韧带骨化(Ossification of the ligamentum flavum,OLF)致椎管狭窄症的临床特点与手术治疗效果。【方法】对手术治疗的孤立型OLF病例进行回顾性研究分析,采用改良胸椎JOA评分法和Epstein标准,手术均采用后路椎板(半椎板或全椎板)切除减压术。【结果】术后随访平均40.3个月。JOA评分:术前7～8点,平均7.7点;术后8～11点,平均10.2点。Epstein标准:优9例,良5例,改善2例。【结论】局灶型OLF临床表现较复杂,必须根据临床特点、影像学及电生理检查进行综合分析并作出诊断。后路椎板切除减压术是治疗局灶型胸椎黄韧带骨化并椎管狭窄症的有效方法。
[Objective] To study the characteristics of diagnosis and surgical treatment for thoracic stenosis caused by focal type ossification of ligamentum flavum （OLF）. [Methods] From 2001 to 2007, 16 cases of focal type ossification of ligamentum flavmn treated surgically by laminectomy or partial laminectomy were studied retrospectively. The neurological status and effect of operative treatment were assessed using the Japanese Orthopaedic Association （JOA） scoring system and Epstein standards. [Results] All patients were followed up for 4 to 60 months with an average of 40.3 months. According to Epstein standards, 9 patients achieved excellent results, 5 good and 2 fair. The preoperative average JOA scale score was 7.7 points （ranged from 7 to 8 points） and the postoperative average JOA scale score was 10.2 points （range from 8 to 11 points）. [Conclusion] Clinical manifestation and neurological examination associated with MRI and CT is the important means for diagnosis of OLF, and laminectomy or partial lamineetomy at the affected level is effective.
