微型骨锚内固定治疗掌骨头骨折临床疗效观察

The efficacy of miniature bone anchor in fixing metacarpal bone fracture

目的探究微型骨锚内固定治疗掌骨头骨折临床疗效观察。方法对照组采用交叉克氏针内固定治疗,观察组采用微型骨锚内固定治疗,观察对比两组临床疗效。结果观察组平均手术时间及平均骨折愈合时间均短于对照组,且术后伤口感染率及骨折延迟愈合率均低于对照组;观察组ATM评定优良率为96.4%,明显高于对照组的78.6%,组间比较差异具有统计学意义(P<0.05)。结论微型骨锚内固定治疗掌骨头骨折临床疗效确切,固定效果显著,术后骨折愈合较快,利于早期开展功能训练,进而改善手部关节功能,值得临床应用和推广。

Objective To explore the efficacy of micro bone anchor in fixingmetacarpal bone fractures. Methods Metacarpal bone fractures in control group were fixed with cross Kirschner wire, and themetacarpal bone fracturesin observation group were fixed using micro bone anchor, eomparethe clinical efficacy of them. Results The mean operative time and average healing time of observation group were shorter than the control group, the postoperative wound infection rate and delayed healing rate were lower than the control group, however the ATM excellent rate of observation group was （96.4%） significantly higher than the control group （78.6%）, the differences between the two groups were statistically significant （ P 〈 0. 05 ）. Conclusions We observed exact efficacy of mini bone anchor in fixing metacarpal bone fracture, such as postoperativefasthealing, which will help to carry out the early functional training, thereby improving joint function of hand, worthy of clinical application and promotion.
