【摘要】目的 研究外固定器治疗桡骨远端不稳定性骨折的有效性和适应证。方法 自1996年10月采用自行设计的动力型外固定器治疗不稳定性桡骨远端关节内粉碎性骨折30例。结果 经平均11.4个月随访，复位质量优22例、良7例、可1例，疗效优19例、良9例、可2例。并发症3例(10%)。结论 (1)外固定器是治疗不稳定性桡骨远端骨折一种方便、有效的方法，动力型外固定器由于可早期活动腕关节，优势更为明显;(2)对固定欠稳定者，可辅以经皮克氏针固定，对并发症则可采取一些有效方法减少其发生;(3)不稳定性骨折，开放性骨折，石膏固定后再移位，桡骨轴向缩短超过3mm，伴有皮肤软组织挫伤或伴有正中神经损伤的骨折可作为外固定器治疗桡骨远端骨折的适应证。

【 Abstract 】 Objective Toinvestigate the feasibility and indications of the external fixation device for treatingunstable distal radius fractures. Methods Thirty cases of unstablecomminuted intra- articularfracture of the distal end of the radius were treated with a new dynamic external fixationdevice. Results All patients were followed up for an average of 11.4months. Anatomically, 22 patients had an excellent result, 7 good,1 fair. And theexcellent functional outcome was seen in 19 patients, good in 9 patients and fair in 2patients. Three patients had complications: metacarpophalangeal fracture of the indexfinger occurred in 1, pin loosening developed in 2. Conclusions Theexternal fixation device was a convenient and effective method. Especially, it makes theearly mobilization of wrist possible. If necessary, an additional Kischner wire might beused to enhance the stability. The use of this new designed device is indicated in thecases of unstable fractures,open fractures, redisplacement after plaster immobilization,more than 3 mm axial shortening of the radius, fractures with soft tissue rupture, or thefractures with median nerve injuries.
