Healing of closed femoral shaft fractures treated with the AO unreamed femoral nail. A comparative study with the AO reamed femoral nail.
Out of a hundred and seven closed femoral fractures, fifty-three were treated with the unreamed femoral nail and fifty-four with the reamed femoral nail. There were four delayed unions in the Unreamed Femoral Nail group (UFN) and three in the Reamed Femoral Nail group (RFN). There were no cases of infection or malunion. Implant failure was the cause of implant conversion in one patient of the UFN group. Healing time of the femoral fractures was 19.2 weeks in the UFN group and 19.6 weeks in the RFN group. Due to the significant decrease in operating time with the UFN (70 min) in comparison with the RFN (125 min) and the possible risk of posttraumatic pulmonary oedema (ARDS) with reaming techniques, the authors recommend the UFN for the treatment of acute closed femoral shaft fractures.
