Generally, we use long stem or interlocking long stem to fix femoral fractures after THA associated with loosening. We report the clinical results of treatment using interlocking nail in five cases of femoral fractures after THA. The subjects consisted of one male and four female, with a mean age of 64 years. Assesment was based on JOA score, estimation of bone union on X-ray, time taken for bone union, estimation of stem sinking and clear zone. Bone union was achieved in four cases and one case showed prolonged bone formation. There were no cases of stem sinking and two cases indicated a clear zone close to the femoral proximal side. Pain relief was anticipated but scores were poor for ADL and articular range of motion. The interlocking long stem state remains good for primary fixation and stability of rotation.
