Abstract: Objective To investigate the effect of micro-plate and screw internal fixation on metacarpal fracture.Methods A total of 80 cases (89 fractures) of metacarpal fractures treated with micro-plate and screw internal fixation from January 2016 to December 2018 were selected in the study, and their clinical data were retrospectively analyzed.Results The average hospitalization duration was (5.12±1.06) d; the average follow-up time was (11.36±3.95) months; the average fracture healing time was (43.6±3.7) d; the excellent treatment rate was 95.51%; the average overall degree of metacarpal joint motion was (236.84±8.06)°; the average ratio of grip force loss in the affected to unaffected side was (2.61±0.21) %; the total incidence of complications was 7.50 %.Conclusion Micro-plate and screw internal fixation for the the treatment of metacarpal fracture has a good effect and prognosis, with a low incidence of complications and a high level of safety.
