Abstract |
Purpose To analyze the clinical results of the modified extension block fixation method using conjoined K-wires for bony mallet fractures.
MATERIALS AND METHODS: From March 2006 to March 2009, we performed conjoined K-wire fixation as a modification of extension block technique in 9 patients with a bony mallet finger. After the average follow-up of 4.8 months, range of motion, pain, nail deformity, and bony union were evaluated.
Results The average range of motion was 3.3degrees (range, 0-20degrees)of extension lag and 76.7degrees (range, 45-90degrees) of flexion. Bony union was obtained in all patients. No nail deformity was observed. One patient complained of distal interphalangeal joint pain.
Conclusion The extension block fixation method using conjoined K-wires can be an acceptable treatment option which provides stable fixation in bony mallet fractures. |
