Clinical effect observation of mini-plate fixation in treatment of metacarpal shaft fracture

Objective To investigate the clinical efficacy of the mini-plate fixation in the treatment of metacarpal shaft fractures.Methods 150 cases admitted to our hospital from March 2009 to June 2012 due to metacarpal shaft fracture and underwent surgery were selected as research objects,of which 90 cases(mini-plate group) were treated with mini-plate fixation and 60 cases(Kirschner wire group) were treated with manual reduction or open reduction with Kirschner wire fixation.The fracture healing time,TAM scoring and incidence of complication were observed in the two groups.Results The fracture healing time of the mini-plate group was(4.6 ± 1.5) weeks,which was significantly shorter than(8.4±1.3) weeks in the Kirschner wire group(t = 3.241,P 0.05).According to TAM ratings of the two groups,good-excellent rate in the mini-plate group was 91.1%,which was significantly higher than the Kirschner wire group(70.0%)(χ2 = 7.135,P 0.05).The incidence of delayed union and nonunion in the micro-plate group and Kirschner group had statistically significant differences(P 0.05).The incidence of infection of the two groups had no significant difference(P 0.05).Conclusion Compared with Kirschner surgery,mini-plate has more significant effect in the treatment of metacarpal shaft fracture surgery,and it is worthy of clinical application.
