AbstractThe intramedullary Kirschner wire fixation of distal metacarpal fractures reported by Foucher et al. combines the known advantages of intramedullary implants with a reduction of iatrogenic soft tissue trauma. We applied this minimal invasive internal fixation technique in 38 patients with fractures dislocated by more than 20 degrees and/or with rotatory deformity. After opening the intramedullary cavity from the base of the respective metacarpal bone and after fracture reduction, two pre-bent Kirschner wires were intramedullary inserted in an orthograde fashion. The pre-bent distal end of the wire in the form of a hockey club allows an additional closed reduction of the displaced distal fracture fragment. Intraoperative complications did not occur. A fixation in a plaster splint followed for one week only. The elastic fixation of the wires working as springs is stable enough to allow physiotherapeutic exercises. After the third postoperative week, the intensity of physical exercise was increased. 36 of the 38 patients were followed. With one exception, all fractures were healed in a proper position. The wires were removed under local anaesthesia on an outpatient basis after six to eight weeks and full mobility of the fingers was achieved in 34 patients at that time. Complications included one redislocation and one distal wire perforation.
