[Valgisation osteotomy of unstable pertrochanteric femoral fracture. Results of 92 patients over 7.75 years].

We report on 92 patients (average age: 76.9 years) with unstable trochanteric fractures (Type A2 and subtypes according to the AO/ASIF-Classification) that were treated by valgisation/medial displacement osteotomy and 130 degrees-angled blade plate fixation during a time period of 7.75 years at the Department of Traumatology of the University Clinics of Frankfurt. Average time in the OR was 106 min, average amount of blood necessary was three units. The rate of complications due to the implant was 14.1% taking into account: "cut out" of blade (four patients), loosening of plate (three patients), failure of implant-breakage (two patients)--and development of delayed union (2 patients). There were 4.3% hematomas and 3.3% infections that required revisional surgery. 16 (17.4%) out of 92 patients died during their hospital stay. 77.2% of surviving patients regained walking ability during their hospitalization and only 12% had to be dismissed to a nursing home. "Pros and cons" of our method of treatment for these fracture types against DHS and gamma-nailing are discussed.
