Simple X-rays (anteroposterior and lateral) of the hip diagnose fracture in the majority of cases. In patients with pain in the hip and an inability to weight-bear with no fracture apparent on plain X-rays, fuher investigation is required. MRI is the most sensitive and specific to diagnose an occult hip fracture, although CT is often readily accessible and sufficient to detect most fractures of the femoral neck or elsewhere in the pelvic ring. If MRI is not available rapidly, CT is preferred. Occult fractures are detected in 50% of patients with normal X-rays and ongoing pain that prevents weight-bearing with additional imaging. Bone scans could be considered if MRI or CT scans are not available.
