title: Osteopenia after plated and nailed femoral shaft fractures.
abstract: Twenty-six patients who had been operated for isolated femoral shaft fractures were studied. Fourteen had been treated with intramedullary nailing and 12 with AO plates. Only nailed patients were allowed early weight-bearing. Bone mineral density and muscle strength in knee extension and flexion were determined. There was a considerable loss of bone mineral in the distal femoral metaphysis and a moderate loss in the tibia. The mean loss was almost identical in the two groups. Muscle power in extension was better preserved in the nailed than in the plated patients. There was a significant correlation between loss of bone mineral and loss of muscle power.
