 We report three cases of subtrochanteric fracture that occurred in a hip affected by coxarthrosis. Coxarthrosis of the hip is rarely associated with an ipsilateral intracapsular femoral neck fracture, but intertrochanteric fractures occur in hips affected by coxarthrosis. Coxarthrosis patients are susceptible to extracapsular fractures because they do not have a full enough range of motion to thrust the femoral neck against the posterior margin of the acetabulum and they have sclerosis of femoral head and neck and osteoporosis. Our three cases were in very old patients and exhibited the same fracture pattern. They suggest that severe osteoporosis in addition to coxarthrosis may cause such subtrochanteric fractures.
