Abstract
Objective To explore the clinical outcomes of treating tendinous mallet finger deformity with Kirschner wire tension traction. Methods From June 2012 to August 2014, 27 patients (27 fingers) with a tendinous mallet finger deformity were treated with Kirschner wire tension traction. Postoperatively a small splint was applied only to protect the extruding K-wires and allowed free movement of the proximal interphalangeal joint and metacarpophalangeal joint. At 6 weeks postoperatively, the K-wires and traction sutures were removed. Active and passive distal interphalangeal joint exercises were initiated immediately afterwards. Results Two patients were lost for follow-up. The rest 25 patients were follow-up for 9 to 16 months postoperatively, with an average of 13 months. According to Crawford′s evaluation criteria, the results were excellent in 7 cases, good in 15 cases and fair in 3 cases. The overall good-excellent rate was 88%. Conclusion Kirschner wire tension traction is an effective treatment for tendinous mallet finger. The procedure is simple yet corrects the deformity and results in satisfactory joint motion.
