Ⅰ期前后联合入路脊髓减压病灶切除内固定治疗颈椎后纵韧带骨化症

目的 探讨Ⅰ期前后联合入路治疗颈椎后纵韧带骨化症（ossification of posterior Iongitudinal ligament，OPLL）的必要性及可行性。方法 自2001年10月至2004年3月采用前路及后路联合减压术治疗颈椎OPLL8例，其中男7例，女1例；年龄32—55岁，平均48．2岁。结果 所有患者均获随访，随访时间为6～30个月。根据日本矫形外科学会（JOA）评分标准，术后评分提高了1～8分，平均4．5分，术后症状改善率4／8。结论 采用Ⅰ期前后联合入路减压成形前路钢板内固定融合术治疗颈椎OPLL具有病灶切除彻底、减压完全、安全有效的特点，是目前治疗该病的较好方法。

One stage anteroposterior decompression and internal fixation for ossification of posterior longitudinal ligament

Objective To evaluate and analyze the results of one stage anteroposterior decompression and internal fixation for ossification of posterior longitudinal ligaments (OPLL). Methods One stage anteroposterior decompression and fixation was carried out from October 2001 to March 2004 in eight cases of OPLL including seven males and one female with age of 32-55 years (average 48.2 years). Results All cases were followed up for 6-30 months. According to criteria of Japan Orthopedic Association (JOA), the postoperative JOA score increased for 1-8 scores (mean 4.5 scores). The postoperative improvement rate of symptom was 50%. Conclusion One stage anteroposterior decompression and internal fixation is a good alternative method for treatment of OPLL, for it has advantages of complete decompression, reliable therapeutic effect and sound recovery.
