Abstract
Objective To compare the clinical results of arthrodesis of the proximal interphalangeal joints by miniplates and Kirschner wires respectively.Methods Fifty-nine cases with 85 intra-articular fractures and bone defects of the proximal interphalangeal joints were treated with arthrodesis by miniplate fixation (Group A,55 lesions in 38 cases) and by K-wire fixation (Group B,30 lesions in 21 cases).The functional outcomes were evaluated using the TAF criteria.Results Postoperative follow-up ranged from 4 to 39 months.There was no infection in group A,while 4 cases in group B had infection.The average duration of bone union was 7.2 weeks (range,6 to8 weeks) for group A and 11.4 weeks (range,7 to 16 weeks) for group B.The time for return to work was 13.1 weeks for group A and 17.9 weeks for group B.Excellent and good rate of 85.5％ (47/55) was achieved in group A,while in group B the excellent and good rate was 66.7％ (20/30).Conclusion Fixation by miniplates is more favorable in treating hand fractures than by using K-wires. Key words: Internal fixators; Arthrodesis; Proximal interphalangeal joints
