弹力带斜“8”固定治疗锁骨外端骨折病例对照研究

目的：应用自行改良研究的弹力带斜“8”字固定治疗锁骨外端骨折，并与手术切开复位锁骨钩钢板内固定比较治疗效果。方法：锁骨外端骨折120例，弹力带斜“8”字固定（手法组）75例，锁骨钩钢板内固定（手术组）45例。结果：骨折愈合时间：手法组平均（6．71±2．35）周，手术组平均（11．38±4．58）周，P〈0．01，差异有统计学意义。骨折愈合率：手法组100％；手术组97．8％，19〉0．05，差异无统计学意义。肩关节功能评定：手法组优56例，良14例，差5例，优良率93.3％；手术组优38例，良5例，差2例，优良率95．5％，19〉0．05，差异无统计学意义。结论：弹力带斜“8”字固定可达到与锁骨钩钢板固定相同的疗效，且骨折愈合时间短、医疗费用低、治疗风险小，是一种经济、实用、安全的治疗方法。

Case-control studies of the treatment for me distal clavicle fracture by elastic band inclined "8" fixation

Objective：To compare the effects of the treatment for the distal clavicle fracture with two different methods. Methods ：There were 120 cases of the distal clavicle fractures involved in the study. Among them, 75 cases were treated by self-improved elastic band inclined＂8＂ fixation （Manipulation group ）, 45 cases were treated by open reduction and internal fixation with clavicular hook plate （Operation group）. Results：There was statistically significant difference between manipulation group （6.71±2.35 weeks） and operation group （ 11.38±4.58 weeks） in the time of fracture union （P〈0.01） ;but,there was no statistically significant difference between manipulation group （100%） and operation group （97.8%） in the rate of fracture union （P〉0.05）. According to the evaluation of shoulder-jolnt function, 56,14 and 5 cases obtained excellent, good and bad result respectively in manipulation group;38,5 and 2 cases obtained excellent,good and bad respectively in operation group. There was no statistically significant difference between manipulation group （93.3%） and operation group （95.5%） in the rate of excellent and good （P〉0.05）. Conclusion：Compared with open reduction and internal fixation with clavicular hook plate, treatment with self-improved elastic band inclined ＂8＂ fixation can shorten the union time of fracture and reduce therapeutic risks, so it is an economical ,practical and safe method for the distal clavicle fracture.
