[Gliding nail osteosynthesis. A new universally applicable implant for management of per- and subtrochanteric femoral fractures].
Age, high physiological load and the great number and different fracture types of the proximal femur are the main challenges for implants used in the management of these fractures. For use in these types of fracture with immediate restoration of full weight-bearing capacity and for reduction of the intra- and postoperative complication rate, the gliding nail was developed. The development is based on a large number of experimental and clinical examinations of per- and subtrochanteric fractures. The advantages of an intramedullary implant and the gliding screw systems are combined with increased moment of resistance of the double-T femor-neck blade profile. We performed a prospective clinical evaluation of the first 186 patients with per- and subtrochanteric fractures who were treated between 15 September 1994 and 29 February 1996 in the Aschaffenburg Trauma Department with a follow-up examination at least 3 months after the operation. The intraoperative complication rate was 1.1%. The postoperative complication rate was 4.9%. Change of the blade because of fracture impaction and tractus iliotibialis problems was the most frequent problem with 2.2%. The most severe complication (1.1%) were caused by subchondral placement of the blade in the cranial one-third of the femur head. In these cases reosteosynthesis was indicated. Ninety-three percent of the survivors were able to return home. The rate of bed-ridden patients (7.7% and 11.7%) was not very different before or after the operation. However, many patients do not reach the condition they had before the fracture and they are one step worse in mobility and social independence.
