Abstract

The treatment of a brachymetacarpia using conventional distraction osteogenesis requires holding an external fixator following distraction for stability, which causes prolonged discomfort that adversely affects the patient's daily activities. This paper reports a case of a 20-year-old male of brachymetacarpia treated with distraction osteogenesis combined with a plate reducing the period of an external fixator, allowing rapid return to the daily activities, and presenting good clinical results.

  Figure 2 The external fixator and plate was prepared (A), and installed directly on the metacarpal bone (B).

  Figure 3 (A) Postoperative radiograph, (B) callotasis at postoperative 4 weeks. (C) At postoperative 7 weeks, callus formation was visible. (D, E) The proximal screws were inserted and the external fixator was removed at the same time. (F) At 12 weeks, slight bowing was observed in the metacarpal bone.
