[Causes for reoperations after osteosyntheses of finger and mid-hand fractures]

31 patients reoperated after osteosynthesis of a metacarpal or a phalangeal fracture were reviewed over a period of three years. The cause of injury was in 18 cases a crush, in six cases a fall, in five cases a saw injury, and in two cases axial trauma. A postoperative plaster splint immobilisation over a period of at least three weeks was carried out in 29 cases. Reoperation was necessary in most of the cases because of a loss of range of motion and a nonunion. The complication rate was independent of the method of fixation, but did depend on the type of injury. Fractures associated with soft tissue injury were more likely to develop complications.
