title: [Mini-invasive fixation of proximal femoral fractures: what benefit for elderly patients?].
abstract: Fixation is used to treat more than two-thirds of proximal femur fractures. The mortality rate is about 25% at one year in these patients, who have an average age of about 80 years. This is mainly due to aging, but also to a gradual deterioration of general health (especially if the operation has been delayed, or after a long stay in the surgical ward) and to local complications (displacement, infection, hematoma). Two fixation devices (a sliding screw plate and a trochanteric nail) have been designed for mini-invasive treatment with fluoroscopic guidance and an incision smaller than 50 mm. The aim is to respect the soft tissues and thereby to avoid local complications, diminish pain, and facilitate early weight-bearing Hospital discharge is possible after 3 or 4 days. Laboratory experiments have shown the satisfactory resistance of the implant and bone at full weight bearing A preliminary series of 30 patients showed the feasibility of these techniques. Primary fusion was achieved in 27 cases. There were no infections and no bleeding, despite antiplatelet treatment. The techniques have now been optimized and multicenter studies are held to determine their real benefit. Fracture fusion and hip motion should be at least as good as with open surgery (90 to 96% fusions, albeit influenced by the precise position of the implants and by osteoporosis). Mortality may be slightly reduced, thanks to immediate operation, early discharge, and fewer local complications. The cost of treatment could also be significantly reduced by the shorter hospital stay. In a few years' time, mini-invasive treatment may become the standard for elderly patients with proximal femur fractures.
