[Occult damage to the femur neck in senile-/inactivity-osteoporosis].

Fractures of the femoral neck in elderly patients are often a complication in osteoporosis. Diagnosis of fractures with displacement and compression of fragments is quite easy. The negative radiograph in old patients complaining of hip pain is generally considered a characteristic feature of presenile osteoporotic pain. Clinical examples present patients with hip pain caused by occult injuries of the femoral neck. They should be regarded as imminent fractures and adequately treated. Bone scan is very helpful in the early detection of such occult osteoporotic injuries.
