颈后纵韧带骨化后脊髓损伤的手术入路选择

摘要

目的 探讨颈后纵韧带骨化后脊髓损伤的外科治疗手术入路选择. 方法 回顾性分析25例颈后纵韧带骨化后脊髓损伤患者手术治疗的临床资料.按照Frankel神经功能分类法分级:A级2例,B级3例,C级14例,D级6例.前路手术12例,后路手术8例,后前路联合手术5例. 结果 术中无大血管、气管、食管、脊髓损伤等严重并发症.所有患者均获随访,时间15～86个月,平均38.3个月,前路手术患者均获骨性融合,内固定无松动、断裂及脱出.后路手术患者术后X线及CT摄片显示无再次关门现象.21例患者脊髓功能获得不同程度改善,4例尤改善者上肢疼痛、麻木有不同程度的缓解. 结论 采用前路、后路或后前路联合入路治疗颈后纵韧带骨化后脊髓损伤均取得良好临床疗效,根据影像学表现结合患者全身情况合理选择手术入路是手术成功的关键.%Objective To investigate the appropriate surgical approach in the management of cervical cord injury following ossification of the posterior longitudinal ligament. Methods The clinical data of 25 patients with cervical cord injury following ossification of the posterior longitudinal ligament who received surgical treatment were retrospectively analyzed. According to Frankel grades, two patients were at grade A, three at grade B, 14 at grade C and six at grade D. The surgical procedures consisted of anterior decompression (12 patients), posterior decompression (8 patients) and combined posteroanterior decompression (5 patients). Results No iatrogenic injury of great vessels, trachea, esophagus or spinal cord occurred. All the patients were followed up for 15-86 months (mean 38.3 months). All segments with anterior fixation attained solid fusion, without implants loosening or breakage. No reelosed open-door was found in patients who received posterior laminoplasty. The spinal function got improved in 21 patients, and a relief of pain or numb of the upper limb was attained in four patients whose spinal cord injury was not cured. Conclusions The surgical outcome of cervical cord injury following ossification of the posterior longitudinal ligament is satisfactory. It is important to select a suitable surgical approach according to the imaging manifestations associated with the general conditions of the patients.
