Osteoarthritis of the hip and fracture of the proximal end of the femur.
The purpose of this investigation was to verify a long-standing clinical observation that patients with fracture of the proximal end of the femur have less evidence of osteoarthritic changes in their hip joints than would have been expected in patients of similar age groups. The radiographs of 342 patients with fractures and those of 157 controls were examined. The statistical results gave uncontroversial evidence that the incidence of osteoarthritic joints was lower in the fracture group. The difference was even greater with severe osteoarthritic changes. This suggests that patients with osteoarthritis have a "better quality" of bone. They are less likely to be suffering from osteoporosis and less liable to fractures of the proximal end of the femur.
