Abstract

PURPOSE
The purpose was to describe comparative analysis of the surgical outcome of percutaneous K-wire fixation of bony mallet fingers reduced with towel clip and 18-gauge needle.
METHODS
We analyzed the bony mallet finger patients with more than twelve months follow-up after percutaneous K-wire fixation. The patients were randomly divided into two groups. Eighteen fingers were treated with closed reduction using towel clip and 18 other fingers were treated with closed reduction using 18-gauge needle.
RESULTS
Radiographs showed bony union and no subluxation in all cases after K-wire removal. The average extension lag was 2.8degrees/1.9degrees, and range of motion of distal interphalangeal joint was 70.3degrees/75degrees respectively. According to Crawford's criteria, excellent results were obtained in 9/11 fingers, good results in 8/7 fingers, and poor result in 1/0 finger, respectively.
CONCLUSION
18-gauge needle reduction in percutaneous K-wire fixation is considered less invasive and useful method for treatment of bony mallet finger with comparable results with towel clip reduction.
