AO多角度锁定钢板治疗老年桡骨远端C型骨折的初步疗效观察

目的总结应用AO多角度锁定钢板治疗老年桡骨远端C型骨折的初步临床疗效。方法2011年3月至2014年2月，采用切开复位、AO多角度锁定钢板固定治疗47例老年桡骨远端c型骨折，其中男15例，女32例，患者平均67．5岁，其中c1型20例，C2型16例，c3型11例。应用上肢功能（DASH）、Gartland和Werley评分进行功能评价及握力和腕关节运动范围评估。结果47例患者，其中43例获得6～12个月随访，平均8．3月，43例骨折均完全愈合，平均愈合时间7N。47例患者中，42例功能评定为优，无并发症。结论切开复位应用AO多角度锁定钢板是治疗骨质疏松性不稳定桡骨远端骨折的有效手段。

AO multiple-angle locking plate in treatment of elderly distal radius type C fractures: a preliminary efficacy

Objective To determine the preliminary clinical effect of AO multiple-angle locking plate on the treatment for the distal radius type C fractures in elderly people. Methods Between March 2011 and February 2014, a total of 47 elderly patients who sustained distal radius type C fractures were admitted in our department and received open reduction and AO multiple-angle locking plate. They were 15 males and 32 females, with an average age of 67.5 years： 20 patients with type C1 fractures, 16 with C2 and 11 with C3. Disabilities of Arm, Shoulder, and Hand （DASH） and Gartland and Werley scoring system were used for clinical functional assessment of the grip strength and wrist motion range. Results Within the 47 patients, 43 were followed up for 6 to 12 （mean 8.3） months and got fully healed finally, with an average healing time of 7 weeks. Forty-two patients had excellent functional assessment and no complication occurred during the follow-up periods. Conclusion Open reduction and AO multiple-angle locking plate are effective approaches for osteoporotic unstable distal radius fractures for the elderly patients.
