Abstract：Objective To investigate the effect of dynamic external fixator with two Kirschner wires and mini plate in the treatment of unstable metacarpal and phalangeal fractures.Methods 60 cases of metacarpal and phalangeal unstable fractures were selected as the research objects.The micro plate group（30 cases）was treated with micro plate internal fixation,and the dynamic external fixator group（30 cases）was treated with two Kirschner wire dynamic external fixator.The clinical efficacy,hospitalization time,operation time and other related indicators of the two groups were compared and analyzed.Results The excellent and good rate of dynamic external fixator group（93.34%）was higher than that of mini plate group（73.33%）（P<0.05）.The operation time,hospital stay,fracture healing time and starting time of functional exercise in the dynamic external fixator group were lower than those in the mini plate group（P<0.05）.The complication rate of dynamic external fixator group（3.33%）was lower than that of mini plate group（20.00%）（P<0.05）.Conclusion The treatment of unstable metacarpal and phalangeal fractures with Kirschner wire dynamic external fixator has better effect and can achieve healing in a short time.It is a safe and valuable treatment scheme.
