The quadratus femoris graft in old transcervical femoral fractures.

Sixteen patients with an old transcervical femoral fracture were treated with the quadratus femoris muscle pedicle bone graft with supplementary autografting. The result was a good functional hip in 14 cases.

Role of pulsed electromagnetic fields in recalcitrant non-unions.

Twenty-nine patients of recalcitrant nonunion of long bones were treated by pulsed electromagnetic fields in an attempt to bring about osteogenesis. The pulse used was rectangular, equal mark space wave in the astable, continuous mode operating at a frequency of 40 Hertz. The success rate was 82.5%. The result was not dependent on the age, sex, time of nonunion or the presence of infection. However, the results were uniformly poor when infection and fracture instability were coexistent in the same patient.
