摘要
目的评价AO微型钢板和克氏针治疗掌、指骨骨折的疗效。方法共评价68例88处掌、指骨骨折病例，分为AO微型钢板组（26例37处）及交叉克氏针组（42例5l处），随访3～12个月（平均5．3个月）。以TAFS评分为评价标准。结果所有病例均达骨性愈合。AO微型钢板组TAFS评分中，优良率为78．4％；而交叉克氏针组为54．9％。两者的TAFS功能评分结果差异有统计学意义（x^2=5．179，P〈0．05），前者明显优于后者。AO微型钢板组延迟愈合率为2．70％；交叉克氏针组为7．84％，前者优于后者。AO微型钢板组平均骨折愈合时间为4．5周，交叉克氏针组为7．6周，两者结果差异有统计学意义（t=2．964，P〈0．05），前者病例骨折愈合时间明显短于后者。两者术后感染率相似。结论AO微型钢板治疗掌、指骨骨折在术后关节功能恢复情况、骨折延迟愈合率及骨折愈合时间、并发症发生等指标上明显优于交叉克氏针固定，但在术后感染率上无明显差异。
Objective To assess the clinical results of metacarpal and phalangeal fractures fixed by AO miniplates and cross K-wires. Methods 88 metacarpal and phalangeal fractures in 68 cases were assessed which were devided into group AO miniplates（37 fractures in 26 cases） and group cross K-wires（51 fractures in 42 cases）. Follow-up were maintained in all cases for 3 - 12 months（average 5.3 months）. The clinical results of both two groups were assessed by the standard of TAPS, infective rate, delayed union rate, fracture union time and complications mohidity. Results There were no nonunions in all cases. According to TAPS scores, the excellent and good rate of group AO miniplates （78.4%） was superior to that of group cross K-wires（54.9% ）, there were of significant difference between them（ x^2= 5.179,P 〈0.05）. All infective cases were found in open fracture cases, the infective rate of group AO miniplates in which 4 of the 11 open fracture cases were infective postoperatively was similar with that of group cross K-wires in which 10 of the 27 open fracture cases were infected. The delayed union rate of group AO miniplates（2.70% ） was superior to that of group cross K-wires（7.84.% ）. The average fracture union time of group AO miniplates（4.5 weeks） was shorter than that of group cross K-wires（7.6 weeks）, there were significant different between them（ t = 2.964, P 〈 0.05）. The complication mohidity in group AO miniplates was lower than that in group cross K-wires. Conclusion The clinical study of metacarpal and phalangeal fractures fixed by AO miniplates are superior to that of those fractures fixed by cross K-wires in such indexes as postoperative function restoration of metacarpalphalangeal and interphalangeal joints, dalyed union rate, average fracture union time and complication mobidity, however, there are of no significant difference in postoperative infective rate.
