[Supracondylar femoral fractures in knee endoprostheses. Stabilizing with retrograde interlocking nail].
The treatment of supracondylar fractures of the femur in total knee arthroplasty is still challenging, and a variety of methods has been recommended. In a retrospective analysis, we reviewed six patients (average age: 70.5 years) with this type of fracture that had been stabilized with a retrograde intramedullary locking nail [Green-Seligson-Henry (GSH) nail]. The fracture had occurred 34.5 months after implantation of total knee arthroplasty. The average time of the operation was 97.16 min. There were no intra- or postoperative complications. All patients could be followed up at 17.3 months on average. Fracture healing was uneventful in all six cases. The postoperative range of motion was similar to the prefracture level in five patients. One patient demonstrated a loss of extension (10 degrees) associated with a valgus malalignment of 10 degrees. According to our experience, retrograde intramedullary nailing of supracondylar fractures in total knee arthroplasty is a promising alternative, which allows closed reduction and preservation of the soft tissue envelope. Immediate mobilization with partial weight bearing is possible, and the rate of complications is low.
