桡骨远端复杂关节内骨折两种治疗策略疗效分析

目的 比较研究锁定加压钢板(LCP)与克氏针结合外固定支架治疗桡骨远端复杂关节内骨折的疗效及适应证. 方法 分别以LCP和克氏针结合外固定支架治疗复杂的桡骨远端关节内骨折共98例,对术后手的握持力、腕关节各方向活动度等方面进行回顾性评估和比较,初步评价其临床疗效. 结果 随访4～20个月,平均12.4个月,均获得骨折愈合.参照1990年纽约骨科医院腕关节评估标准,对于AO/ASIF分型C1、C2型骨折,LCP组与克氏针结合外固定支架组疗效比较,差异无统计学意义(P>0.05),C3型骨折克氏针结合外固定支架疗效优越(P<0.05).结论对于闭合性桡骨远端C1、C2型骨折,可选择掌侧LCP或克氏针结合外固定支架固定.而对于远端粉碎严重的C3型骨折,选择克氏针结合外固定支架疗效相对优越.

Comparison of efficacies of two fixation methods in treatment of complex intra-articular fracture of the distal radius

Objective To compare the efficacies and indications of locking compression plate (LCP) and external fixator plus Kirschner wires in treatment of complex intra-articular fracture of the dis-tal radius. Methods Ninety-eight patients with complex intra-articular fractures of the distal radius were treated with volar LCP or external fixator plus Kirschner wires, the efficacies of which were evaluated by comparing the grasping force and wrist function of the patients. Results All the patients were fol-lowed up for an average of 12.4 months, which showed fracture healing in all the patients. According to the wrist function assessment system of New York Orthopedic Hospital (1990), there was no statistical difference in the efficacy of LCP and external f'lxator plus Kirschner wires in treatment of types C1 or C2 fractures (P > 0.05), while the efficacy of external fixator plus Kirschner wires was significantly superior to that of LCP in treating type C3 fracture (P < 0.05). Conclusions For types C1 or C2 intra-articu-lar fractures of the distal radius, the efficacies of LCP and external fixator plus Kirschner wires are simi-lar, while the efficacy of external fixator plus Kirschner wires is superior to that of LCP in treating type C3 intra-articular fracture of the distal radius.
