The outcomes of 218 little finger metacarpal shaft and neck fractures that had been treated non-operatively, with no attempt at fracture reduction, were compared with those of 44 that had been treated operatively with fracture reduction and fixation (plates or K-wires). Outcome measures included the grip strength of the little finger and the DASH score. Fracture malunion was assessed by clinical measurement of little finger ray shortening and measurement of palmar angulation on the initial radiographs. The severity of palmar angular deformity did not affect the outcome of the 105 metacarpal neck or 113 metacarpal shaft fractures that had been treated non-operatively. There were no differences between the outcomes of the 18 metacarpal neck fractures treated operatively and the 105 treated non-operatively. The DASH score (P = 0.001) and aesthetic outcome (P = 0.013) were significantly better for the 113 metacarpal shaft fractures treated non-operatively than for the 26 treated operatively.

Key Words: metacarpal fractures • malunion • outcome
