This retrospective study of 2,173 consecutive low friction arthroplasties at Wrightington Hospital characterizes the incidence, radiographic distribution, patient risk factors, and functional consequences of ectopic bone formation after total hip replacement, and introduces a detailed anatomic classification system grading ectopic bone by location and quantity.
When counseling patients about hip arthroplasty risks, consider that males and those with limited preoperative motion face higher heterotopic ossification risk. History of heterotopic ossification after prior hip surgery should prompt prophylaxis discussion before contralateral procedures.
