改良Weaver-Dunn技术治疗急性肩锁关节脱位

CLINICAL STUDY ON SURGICAL REPAIR OF ACUTE ACROMIOCLAVICULAR DISLOCATION BY MODIFIED WEAVER-DUNN TECHNIQUE

目的 探讨改良 Weaver- Dunn技术在治疗急性肩锁关节脱位中的应用价值。方法 1993年 1月～1998年 12月 ,对 18例急性肩锁关节脱位采用改良 Weaver- Dunn技术 ,另 17例采用肩锁关节张力带内固定术治疗 ,术后随访 12～ 36个月。采用宾西法尼亚大学肩关节功能评分标准 ,对比研究改良 Weaver- Dunn技术在治疗急性肩锁关节脱位中的应用效果。结果 采用改良 Weaver- Dunn技术较采用肩锁关节张力带内固定术后患者近期肩关节功能恢复快 ;术后 12、2 4和 36个月 ,采用改良 Weaver- Dunn技术治疗的结果评分分别为 (189.7± 6 .7)分、(193.7± 3.6 )分和(194 .7± 3.4 )分 ,采用肩锁关节张力带内固定的治疗结果评分分别为 (16 7.3± 7.80 )分、(170 .2± 6 .3)分和 (16 5 .6±5 .9)分。统计学处理两组之间具有统计学意义 (P<0 .0 5 )。结论 与肩锁关节张力带内固定比较 ,改良 Weaver- Dunn技术是一种治疗急性肩锁关节脱位较理想的方法。

Objective To investigate the clinical value of modified Weaver Dunn technique in repair of acute acromioclavicular dislocation. Methods From January 1993 to December 1998, 18 cases of acromioclavicular dislocation were treated by modified Weaver Dunn technique, and other 17 cases of the same suffering were treated by tension band fixation of the acromioclavicular joints. All of the patients were followed up for 12-36 months before clinical evaluation of the function of shoulder joints, according to University of Pennsylvanian Shoulder Score System. Results In short term, the shoulder joints recovered much more rapidly in the cases repaired by modified Weaver Dunn technique; 12, 24 and 36 months after operation, the scores of the cases repaired by modified Weaver Dunn technique were (189 7±6 7), (193 7±3 6) and (194 7±3 4) respectively according to the Shoulder Score System, while those of the cases treated by tension band fixation were (167 3±7 8), (170.2±6 3) and (165 6±5 9) respectively. The above data indicated that there was significant difference between two groups ( P< 0.05). Conclusion The modified Weaver Dunn technique was a better surgical approach than tension band fixation for repair of acute acromioclavicular dislocation.
