Abstract：Objective:To compare the effect of open reduction with mini T-shaped condylar plate fixation and closed reduction with mini external fixator fixation in the treatment of 2nd to 5th metacarpal neck fracture.Method:A total of 60 patients with 2nd to 5th metacarpal neck fracture admitted to the First Affiliated Hospital of Bengbu Medical College from January 2020 to December 2022 were selected and divided into two groups according to random number table method,with 30 cases in each group.Group A was fixed with open reduction with mini T-shaped condylar plate fixation,and group B was fixed with closed reduction with mini external fixator fixation.The operative conditions,functional status of finger joint,pain medium and complication rate of the two groups were observed.Result:The operation time of group B was shorter than that of group A,and the intraoperative blood loss was less than that of group A,the differences were statistically significant(P<0.05).After 6 months of follow-up,the total excellent and good rate of finger joint function and grip strength in group B were higher than those in group A,and the differences were statistically significant(P<0.05).Before operation,there were no significant differences in 5-hydroxytryptamine(5-HT)and neuropeptide Y(NPY)between the two groups(P>0.05).At 24 h after operation,5-HT and NPY in both groups were higher than those before operation,and the differences were statistically significant(P<0.05),but there were no statistical significances between the two groups(P>0.05).There were no significant differences in the incidence of complications between the two groups(P>0.05).Conclusion:Open reduction with mini T-shaped condylar plate fixation and closed reduction with mini external fixator fixation is similar influence the pain media levels and complications.However,the effect of closed reduction and micro external fixation is better,and the functional recovery of finger joint is better.
