title: Heterotropic bone formation as a complication of elective joint replacement in haemophilic patients - a case report and literature review.
abstract: We report two cases of this rare postoperative condition. Both patients having undergone extensive surgery to their hips, developed increased bone growth in the soft tissue of the hip, accounting for the reduced range of movement, pain and stiffness. Plain x-rays taken confirmed the presence of heterotopic ossification, also known as a variant of myositis ossificans. We review the literature and discuss treatment options of this rare condition in patients with end-stage haemophilic arthropathy.
