Effect of locking compression plate for treatment of old distal radius fracture

Objective To observe the clinical efficacy of locking plate in the treatment of old distal radius fracture. Methods From January, 2010 to March, 2016, 38 cases of old distal radius fractures were treated with volar or dorsal locking plate. They were 17-77 years old, with a mean age of 51.1. According to AO classification, there were 16 cases of type A, 10 type B, and 12 type C. 27 cases were operated by volar approach, and the other 11 cases by dorsal approach. Results The mean follow-up period was 57.1 months (15.6 to 90 months). According to Cooney wrist score standard, the results were excellent in 21 cases, good in 12, and fair 5 cases, with an excellent and good rate of 86.8%. Conclusion The malunion of old distal radius fracture significantly affects the wrist joint function. The treatment should focus on restoring the anatomical angle of the distal radius and the articular surface smoothness. Active rehabilitation exercises after operation can promote the functional recovery of wrist joint. Key words: Distal radius fracture; Old fracture; Internal fixation; Locking compression plate
