Management of trochanteric fractures of the femur with external fixation in high-risk patients.

The aim of this prospective study was to assess the outcome of trochanteric fractures of the femur after external fixation in a group of elderly patients with high surgical risk. The study population consisted of 50 patients with trochanteric fractures of the femur and a mean age of 87 years who were classified by an anaesthetist as ASA 3 or 4 and considered not suitable for conventional fractures fixation. The fracture was fixed with an external fixator under spinal anaesthesia. The final follow-up was at 12 months. All fractures healed within 12 weeks. Superficial pin tract infection occurred in 30 patients, and fracture united with a shortening of 14 mm (5-20) in 12 patients. No implant failures or limitation of knee movements were recorded. Five patients died within 1 year. External fixation is a valuable treatment alternative for trochanteric fracture of the femur in elderly patients.
