目的总结经肌间隙入路后路复位联合改良前路支撑植骨内固定术一期治疗腰椎骨折脱位的临床疗效。方法2002年1月-2006年2月,采用一期经肌间隙入路后路复位联合改良前路支撑植骨内固定术治疗腰椎骨折脱位24例。男17例,女7例;年龄22～69岁。高处坠落伤9例,车祸伤15例。损伤节段:L15例,L210例,L34例,L42例,L1、21例,L3、42例。AO分型:B型6例,C型18例;神经功能Frankel分级:A级5例,B级11例,C级7例,D级1例。评估术后神经功能恢复情况,行影像学检查,测定Cobb角。结果术后19例获随访,随访时间8～52个月,平均28.4个月。2例术前FrankelA级患者1例恢复至C级,1例无改善;9例B级患者,5例恢复至C级,2例恢复至D级,2例无改善;7例C级患者,5例恢复至D级,2例恢复至E级;1例D级患者恢复至E级。术前、术后3d及末次随访Cobb角分别为(-11.5±4.6)、(4.2±4.7)和(4.0±4.8)°,术后3d及末次随访Cobb角与术前比较,差异均有统计学意义(P<0.001);末次随访与术后3d比较差异无统计学意义(P>0.05)。影像学检查示融合位置良好,无植骨块(钛网)移位、沉降及断钉、断棒和松动等现象。结论经肌间隙入路后路复位联合改良前路支撑植骨内固定术治疗严重腰椎骨折脱位可一期完成复位、减压、植骨和内固定,最大程度保护了脊柱后柱结构的完整性,减少了对椎旁软组织进一步的损伤,手术时间短、术中出血少、内固定牢固,临床疗效满意。
Objective To evaluate the clinical outcomes of modified posterior-anterior operation in the treatment of serious lumbar fracture and dislocation. Methods From January 2002 to February 2006, 24 patients, 17 males and 7 females aged 22-69 years, underwent reduction of posterior spatium intermuscular approach combined with modified anterior operation. Nine cases were caused by falling and 15 by traffic accident, involving： L1 in 5 cases, L2 in 10 cases, L3 in 4 cases, L4 in 2 case, LI; in 1 case and L3,, in 2 cases. According to the Frankel grade, there were 5 cases for grade A, 11 for grade B, 7 for grade C and 1 for grade D. The recovery of neurological function was evaluated. The imageology examination was applied to evaluate the condition of internal fixation and bone union. The Cobb＇ s angle was measured by X-ray film before operation, 3 days after operation and at the final follow-up, and the difference was estimated. Results Nineteen patients were followed up for 8-52 months, 28.4 months on average. Among the 2 cases of grade A, one improved to C and the other had no improvement. Among the 9 cases of grade B, 5 improved to C, 2 improved to D, and other two had no improvement. Among the 7 cases of grade C, 5 improved to D and 2 improved to E. One case of grade D improved to E. The average Cobb＇ s angle was （-11.5 ± 4.6）^o preoperatively, （4.2 ± 4.7）^o 3 days after operation and （4.0 ± 4.8）^o at the final follow-up, indicating there was a significant difference between preoperation, 3 days after operation and the final follow-up （P 〈 0.001）, but no significant difference between 3 days after operation and the final follow-up （P 〉 0.05）. The position of internal fixation was good during follow-up. The complications such as disruption, loosening and collapse were not observed. Conclusion Reduction of posterior spatium intermuscular approach combined with modified anterior operation in the treatment of serious lumbar fracture and dislocation could complete the reduction, decompression, grafting and internal fixation in one stage, and protect the paraspinal soft tissue and minimize the trauma caused by surgery. It has the merits of short time of operation, small amount of intraoperative hemorrhage, solid union of internal fixation and satisfactory clinical outcome.
