RESUMO
Objective To discuss the clinical efficacy of internal fixation with miniature steel plate and kirschner pins in treatment for metacarpal neck fracture.Methods A total of 142 patients with cervix metacarpal fracture in our hospital from January 2015 to December 2016 were divided into the control group(n =71) and the observation group(n =71) randomly.The patients in control group were treated with internal fixation with kirschner pins,and the patients in observation group were treated by internal fixation with miniature steel plate.The operative time,postoperative healing time,postoperative pain,metacarpophalangeal joint function and complications were compared between the two groups.Results The operation time of observation group was (38.4 ± 3.8) minutes,the fracture healing time was (3.1 ± 1.4)weeks,the excellent and good rate of TAM was 97.2％ after operation,the excellent and good rate of FAFS was 98.6％ after operation,all these indexes were significantly better than those in the control group with statistical significance (P ＜ 0.05).Conclusion Internal fixation with miniature steel plate in the treatment of cervix metacarpal fracture has the advantages of exact clinical effect,short operative time,quick fracture healing and good recovery of joint function.
