Favorable results of the surgical treatment of intra-articular crush fractures of the distal femur]

Severely comminuted intra-articular femoral fractures are usually associated with major soft-tissue damage as a part of serious multiple injuries. Surgical treatment should aim at exact anatomical restoration of the articular surface. Internal fixation should be stable so that functional after-treatment is possible, a condition of achieving an optimal result. In a period of over 7 years, 24 patients with 26 intra-articular comminuted fractures were operated on. Twenty patients had multiple injuries (ISS > 18), 11 fractures were complicated. Postoperatively, impaired wound healing occurred in three elderly patients; in two of these amputation was necessary. Considering the severity of the injury, the long-term results were good: ten of the 16 patients examined with 18 fractures recovered completely, in the other cases the functional result wa adequate to good. Surgical treatment of comminuted intra-articular fractures of the distal femur is to be adapted to the individual case; depending on the fracture type and the associated damage a selection is to be made from various implants and techniques. With consistent, individually adapted application of the current AO techniques good results can be obtained.
