儿童上肢牵引复位固定器结合夹板治疗肱骨髁上骨折的疗效观察

Treatment of Fracture of Upper Extremity with the Upper Extremity Multifunction Traction Reduction Fixator

目的:观察小儿上肢多功能牵引复位固定器治疗肱骨髁上骨折的临床疗效。方法:肱骨髁上骨折患儿485例,均采用上肢多功能牵引复位固定器治疗。结果:解剖对位356例,近解剖对位96例,功能对位33例。骨折临床愈合时间21～42d,平均31.5d,随访1～5年。功能恢复:优426例,良56例,差3例,肘内翻发生率5.15%。结论:儿童上肢多功能牵引复位固定器与骨折端所形成的三维立体固定,适合上肢的生物力学要求,为儿童上肢骨折的治疗提供了一种既能纠正骨位,又稳定整复骨折,并能防止旋转,结构稳固、简单、操作使用方便、有效、安全。值得临床推广。

Objective： To study the effect of the upper extremity multifunction traction reduction fixator on supracondylar fracture of humerus in children. Methods：A total of 481 children patients with supracondylar fracture of humerus were all treated by the upper extremity multifunction traction reduction fixator. Results： There were 356 cases of anatomical contraposition, 96 peri--anatomical contraposition, and 33 functional contraposition. The clinical healing duration was 21 -42 days, averagely 31.5 days. The follow-up lasted from 1 to 5 years. Excellent recovery of function was observed in 426 cases, fine in 56, and poor in 3. The incidence of cubitus varus was 5.15%. Conclusion：The upper extremity multifunction traction reduction fixator can form a three-dimensional solid fixation with the broken extremity, and meet the requirement of upper limb biomechanics, deserving more wide clinical application.
