Abstract:Objective: To explore the risk factors of wrist joint recovery after traumatic distal radius fracture fixation. Methods: From August 2011 to October 2017, 98 patients with traumatic distal radius fracture were selected and divided into good group and bad group according to the recovery effect of wrist joint 6 months after operation. The clinical characteristics of the two groups were compared, including sex, age, body mass index, time of treatment, osteoporosis, fracture type, fracture AO classification, injury energy, fracture of styloid process of ulna, last reexamination of palm angle, last reexamination of radial shortening and functional exercise. Logistic regression model was used to analyze the risk factors of poor wrist joint recovery after fixation of traumatic distal radius fracture. Results: Among the 98 patients, 26 cases recovered poorly, accounting for 26.53%, 72 cases recovered well, accounting for 73.47%. The proportion of irregular exercise was 53.85%, 65.38%, 57.69%, 46.15%, 46.15% and 42.31% in the poor group, which was higher than 31.94%, 15.28%, 16.67%, 16.67%, 15.28%, 9.72% in the good group (P<0.05). Logistic regression analysis showed that age (> 65 years), osteoporosis, comminuted fracture, palmar tilt angle at the last reexamination (< 10 degrees), radial shortening (> 5mm) at the last reexamination, and functional exercise (irregular) were the risk factors for poor wrist recovery (P<0.05). Conclusion: The poor recovery of wrist joint after internal fixation of traumatic distal radius fracture is closely related to age ≥ 65 years old, osteoporosis, comminuted fracture, palm angle < 10 度, radius shortening ≥ 5mm and irregular functional exercise.
