Concurrent Bilateral Femoral Neck Stress Fractures and Osteonecrosis of the Hip

Although bilateral osteonecrosis of the femoral head and bilateral stress fracture of the femoral neck are well-documented conditions, the occurrence of both conditions in the same patient has not been reported, to our knowledge. We present the case of a patient with both entities who was managed with internal fixation of both hips, which provided stabilization of the stress fractures as well as treatment of the osteonecrosis with core decompression. Two years after treatment, the stress fractures had healed and there was no evidence of progression of the osteonecrosis.
