Purpose: To evaluate the clinical results of the treatment of the percutaneous Kirschner wire fixation of bony mallet finger using an 18 gauge needle.
Materials and Methods: From September 2002 to September 2009, we performed closed reduction using an 18 gauge needle and percutaneous fixation with Kirschner wire for 15 cases of bony mallet finger and followed up at least 1 year. The fractures were classified by the Wehbe and Schneider’s method. Indications of operative treatment were fractures involving more than 30% of articular surface, fracture fragments displaced more than 3 mm, or subluxation of the distal interphalangeal joint. The results were evaluated by the Crawford criteria.
Results: All the fractures united, with an average healing time of 5.3 weeks(4-6 weeks). According to Crawford criteria, 10 cases were excellent, 5 cases were fair at a mean follow-up of 13 months. There were no pin tract infections and migrations of the pin.
Conclusion: Percutaneous Kirschner wire fixation of mallet finger using an 18 gauge needle is an easy technique which can achieve anatomical reduction and diminish operation-related complications
