目的探讨后方经椎弓根入路脊髓减压术治疗的临床效果.方法回顾性分析自2006年3月至2009年12月北京宣武医院神经外科行后方经椎弓根脊髓减压术的7例胸椎后纵韧带骨化的患者,通过手术前后症状改善和手术疗效对比,评估该方法的安全性和有效性.结果术后随访时间平均13.7个月,5例术后下肢运动功能显著改善,1例术后一过性单侧下肢肌力下降,1例左下肢瘫痪.神经根性症状和二便功能术后均有较好缓解.末次随访时JOA评分较术前提高2.9分,术后复查脊柱稳定性良好.结论后方经椎弓根入路脊髓减压术治疗胸椎后纵韧带骨化是安全有效的.

Objective To report the key points and clinical outcomes of posterior bilateral transpedicular approach circumspinal decompression for thoracic ossification of the posterior longitudinal ligament.Methods The author retrospectively reviewed the cases of 7 consecutive patients presenting with OPLL in whom surgery was performed via a transpedicular approach from Mar.2006 to Dec. 2009. We evaluated the spinal function and surgical outcome during the follow up,and investigated the safety and effectiveness of this procedure.Results Mean follow up period was 13.7 months.Of those with weakness of lower extremities,5 of 6 regained muscle strength.One presented temporary muscle strength worse and recovered after rehabilitation training.One presented the paralysis of left lower extremity.5 patients relieved from the back pain.3 patients presenting dysfunction of urinary and fecal improved. No patient suffered postoperative spinal instability-related pain or delayed kyphosis.Conclusion Posterior bilateral transpedicular approach for circumspinal decompression is a safe and effective way to treat thoracic ossification of the posterior longitudinal ligament.
