AO微型钢板与克氏针治疗掌指骨骨折临床观察

目的：探讨应用AO微型钢板及克氏针内固定治疗掌指骨骨折的临床疗效。方法：采用AO微型钢板治疗掌指骨骨折40例,克氏针内固定治疗41例,比较两种手术治疗效果。结果：AO微型钢板内固定组的骨折均达解剖复位,悉数愈合,仅1例延迟愈合,平均愈合时长5.1周。克氏针内固定组1例骨折未愈合,其余骨折全部愈合,仅3例延迟愈合,平均愈合时长8.0周。AO微型钢板组优34例,良5例,差1例,优良率为97.5%;克氏针组优者26例,良5例,差10例,优良率75.6%。两组的优良率比较差异有显著性（即P〈0.05）。结论：AO微型钢板质薄、体小、坚强,固定牢靠,能早期功能锻练,其疗效优于克氏针内固定,是掌指骨骨折的一种理想固定方法。

Clinical Observation of Treating Metacarpal and Phalangeal Fractures by Applying AO Mini-Plate and Kirschner Wire

Objective：To explore the AO mini-plate and Kirschner wire internal fixation to treat metacarpal and phalangeal fractures of applging.Methods：To Apply AO mini-plate therapy for the treatment of metacarpal and phalanx fractures in 40 cases,and Kirschner wire fixation in 41 cases,then compare the two kinds of operation treatments.Results：The AO mini-plate fixation group reached the anatomical reduction of fracture healing.All the cases were healed except 1 case of delayed healing and the average healing time was 5.1 weeks.Except 1 case of uncured fracture,all the fractures in the internal fixation of Kirschner wire group were healed.Only 3 cases of delayed healing and the average healing time was 8 weeks.AO mini-plate group was excellent in 34 cases,effective in 5 cases,poor in 1 cases,the excellent and effective rate was 97.5%;Kirschner wire group excellent in 26 cases,effective in 5 cases,poor in 10 cases,the excellent and effective rate was 75.6%.The excellent and effective rate of two groups had significant difference（P〈0.05）.Conclusion：AO mini-plate,with its characters of thin,small,strong and reliable fixation,can provide early functional exercise and its effect is better than Kirschner wire internal fixation of metacarpal and phalangeal fracture,which is a kind of ideal fixation method.
