Abstract: ［Abstract］ Objective To explore the influencing factors of rehabilitation effect of patients with distal radius fracture after operation. Methods Ninety patients with distal radius fracture treated in our hospital from July 2012 to July 2016 were included in the study. The wrist motion， hand grip strength and Michigan functional score at 3， 6 and 12 months after operation were recorded as strain variables to characterize the rehabilitation effect of patients after operation. The wrist motion， hand grip strength and Michigan Hand Outcome Questionnaire （MHQ） at 3， 6 and 12 months after operation were recorded as strain variables to characterize the rehabilitation effect of patients after operation. One?way linear regression was used to determine the relationship between the possible influencing factors. The independent variables of P<0.05 were included in the multivariate logistic regression analysis to determine the risk factors of rehabilitation effect. Results During the 12?month follow?up， 2 patients had screw infection， 2 patients mild screw loosening at 1 month， and 1 patient developed carpal tunnel syndrome at later stage. The grip strength， range of motion and MHQ improved continuously at 3， 6 and 12 months after operation. Univariate analysis showed that trauma energy， fracture type， age， bone mineral density and fixation time of external fixator were closely related to the rehabilitation effect after operation in 3 months after operation （P<0.05）； Fracture type， traumatic energy and fixation time of external fixator were closely related to the rehabilitation effect after operation in 6 months after operation （P<0.05）； Age， bone mineral density and fracture type are closely related to the rehabilitation effect after operation in 12 months （P<0.05）. Multivariate logistic regression showed that severe fracture type， high energy trauma and long external fixator fixation time were risk factors affecting the recovery of patients with distal radius fracture after 3 months （P<0.05）； Severe fracture types and high energy trauma were risk factors affecting the recovery of patients with distal radius fracture after 6 months （P<0.05）. Decreased bone mineral density and increased age were risk factors affecting the recovery of patients with distal radius fracture after 12 months （P<0.05）. Conclusion In the tresent study， severe fracture types， high?energy trauma and long external fixator fixation time were risk factors affecting the rehabilitation of patients with distal radius fracture after 3 months of operation， and fracture types and high energy trauma were the risk factors at 6 months， while decreased bone mineral density and increased age were risk factors at 12 months. Whether distal radius fracture was complicated with ulnar styloid process fracture and the length of fixation were not closely related to the rehabilitation effect.
