Abstract

PURPOSE
To analyze the treatment of clinical results of the percutaneous Kirschner wire fixation of acute mallet fractures percutaneousely reduced by towel clip. MATERIALS AND METHODS: From August 2005 to April 2009, we evaluated nine fingers in eight patients, more than three months follow up. The type of injury was a axial loading in seven cases and direct blow in two. The average follow-up period was 10.1 months (range: 3~41 months). The indication of operative treatment was the presence of large bony fragment or the palmar subluxation of the distal phalnx. RESULTS: The range of motion was 3.7degrees (0~10degrees) in extension lag and 76.7degrees (60~90degrees) of flexion of the distal interphalangeal joint. CONCLUSION: The percutaneous Kirschner wire fixation of acute mallet fractures percutaneousely reduced by towel clip is one of the easy and simple method to stabilizing of bony mallet fracture.

Figure

  • Fig. 1 Preoperative lateral radiograph shows a displaced mallet fracture.

  • Fig. 2 Reduction using a towel clip under fluoroscopic guidance. Full extended DIP joint can reduce and compress the bone fragment by tips of a towel clip. Occasionally, manipulation of the distal phalanx with a towel clip is required to obtain an anatomic reduction.

  • Fig. 3 Maintaining reduction by a towel clip, a 0.035 inch K-wire is inserted through the bony fragment at a 45 angle into the of distal phalanx from dorsal to palmar cortex.

  • Fig. 4 After removal of a towel clip, a second K-wire is inserted through the bony fragment to distal phalanx.

  • Fig. 5 A temporally additional K-wire is inserted for stability.

  • Fig. 6 6 weeks follow up radiograph after the removal of the K-wires.
