Is magnetic resonance imaging (MRI) necessary to exclude occult hip fracture?
The possibility of occult hip fracture in older patients after a fall is a common problem in emergency and orthopaedic departments. Magnetic resonance imaging (MRI) scanning is the best investigation, but is expensive and may be difficult to obtain. The value of various clinical signs to determine which patients are at risk of occult hip fracture has not been reported. We reviewed all patients who had MRI scan for suspected hip fractures but had normal initial X-rays over a 6-year period. We identified 76 patients. Twelve patients were excluded. Two patients had MRI scan for suspected stress fracture and two patients had metastatic fractures. Eight patients had inadequate or untraceable clinical notes. Each patient’s personal details, mobility, independence and detail clinical details were recorded. Following case review of 64 patients we excluded 5 patients with associated osteoarthritis of the hip joint, 1 patient with fibromyalgia and 1 patient with pre-existing multiple myeloma. Th
