Abstract

There are very few therapeutic alternatives for patients with proximal femoral epiphyseal bone deficit combined with a fracture at another level and signs of infection. This combination can be successfully managed with a proximal femur megaspacer. This article is intended to review our variation of this technique and to show the initial results obtained from 11 cases. Of these 11 cases, there were 6 women and 5 men. The mean age was 66 years. The average number of previous surgeries was 3. Definitive prosthetic reconstructive treatment was achieved in 7 of these 11 subjects. The average time to reimplantation was 11.7 months. Fractures or nonunion healed uneventfully. Bone union and infection control were achieved in 10 of the 11 patients.
