Indirect reduction with a condylar blade plate for osteosynthesis of subtrochanteric femoral fractures.
Subtrochanteric fractures frequently occur as high energy trauma usually in younger patients and may lead to severe comminution of the medial cortex. The medial cortex of the proximal femur is exposed to high compressive forces which make fracture stabilization a difficult problem. Bone healing may be seriously compromised due to extensive comminution and fragment devitalization. This requires reduction techniques which do not cause additional damage to the vitality of the bone. With indirect reduction techniques and the use of a condylar blade plate the results have been significantly improved in these fracture types in our department (1). In this report the essential aspects of indirect reduction for subtrochanteric fractures using a condylar blade plate and the treatment results from our department from earlier years (1) and from the last 2 1/2 years will be presented. In the latter period, fifteen patients with a mean age of 49 years (19-87 years) were treated with this method. Fractures resulted from traffic incidents or falls from a great height in 11 cases (73%). Union was achieved in 14 cases (93%) with full weight-bearing after a mean of 3 months (1-4 1/2 months). Malunion was seen in two cases (13%) without the need for further surgery. Non union occurred in one patient (7%) with a III B open injury due to early infection. After repeated debridements, bone grafting and decortication, the fracture was stabilized with a replacement condylar blade plate and healed uneventfully.
