Bilateral heterotopic ossification after bilateral hip arthroplasty in a geriatric patient

摘要

The case of a geriatric patient with total hip arthroplasty for coxarthrosis and an inpatient fall 12 days after the first operation is reported. Six weeks after the first operation, the patient reported new pain in the area of both hips and thighs. X-ray and scintigraphy confirmed the diagnosis of bilateral heterotopic ossification. NSAID therapy was started, and rapid improvement was observed. At discharge, the patient was able to walk with aids in- and outside. At the 12-month follow-up, x-ray control showed Brooker state 3 for the right and 4 for the left hip. Walking ability did not change during follow-up.
