Contralateral fracture of the proximal femur. Implications for planning trials
1Department of Medicine, Wellington School of Medicine, Wellington South, New Zealand.
Abstract:
In three consecutive years 462 patients over the age of 60 years presented at Waikato Hospital, Hamilton, New Zealand, with a fracture of the proximal femur. Within two years, 11 (2.4%) returned with a fracture of the contralateral femur. If the effectiveness of any form of treatment aiming at reducing the incidence of contralateral fracture were subjected to a trial, a sample size of 5000, randomly distributed equally between treatment and placebo groups, would be needed for the trial to have a power of 80% to detect a reduction.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
