From 1987 to 1991, we treated 53 patients with 54 fractures of the acetabulum by reconstruction through a posterior or an extended iliofemoral surgical approach. For prophylaxis against heterotopic ossification we used perioperative irradiation and indomethacin. Indomethacin was given as daily doses of 25 mg started within 24 hours of operation and continued for four weeks. Irradiation was by e...

In patients with severe quadriplegic cerebral palsy and painful hip dislocation proximal femoral resection arthroplasty can reduce pain, but the risk of heterotopic ossification is significant. We present a surgical technique of autologous capping of the femoral stump in order to reduce this risk, using the resected femoral head as the graft. A retrospective study of 31 patients (43 hips) who h...

Symptomatic heterotopic ossification of abdominal surgical incisions is a rare occurrence. We present a 67-year-old man with severe discomfort caused by heterotopic ossification extending from the xiphoid to the umbilicus. The patient underwent an abdominal aortic aneurysm repair 3 years before our treatment. A 13 × 3.5 cm ossified lesion was excised. The resulting midline defect was closed usi...

The carcass of a stranded southern right whale Eubalaena australis, discovered on the coast of Golfo Nuevo in Península Valdés, Argentina, exhibited extensive orthotopic and heterotopic ossification, osteochondroma-like lesions, and early degenerative joint disease. Extensive soft tissue ossification led to ankylosis of the axial skeleton in a pattern that, in many respects, appeared more simil...

Zygomatico coronoid ankylosis is a rare type of extra articular ankylosis. The most common cause is Jacobs Disease, which is due to osteochondroma of the coronoid process. In this paper we present a case where in the zygomatico-coronoid ankylosis is due to heterotopic ossification, secondary to surgical trauma from previous operations. A literature search does not show any similar reported case...

Demineralized bone matrix has been successfully commercialized as an alternative bone graft material that not only can function as filler but also as an osteoinductive graft. Numerous studies have confirmed its beneficial use in clinical practice. Heterotopic ossification after internal fixation combined with the use of demineralized bone matrix has not been widely reported. In this paper we de...

Heterotopic ossification following joint replacement in the lower limb occurs in 3% to 90% of cases. Higher grades of heterotopic ossification can result in significant limitation of function and can negate the benefits of joint replacement. The understanding of the pathophysiology of this condition has improved in recent years. It would appear to be related to a combination of systemic and loc...

UNLABELLED Heterotopic mesenteric ossification is a rare clinical entity with less than 40 reported cases. Moreover, heterotopic mesenteric ossification around a stoma is described in fewer cases. CASE PRESENTATION An 81-year-old male patient, who underwent a sigmoidectomy two years ago for a sigmoid colon cancer, was admitted in our Department in order to be investigated for a local recurren...

The purpose of this retrospective clinical study was to evaluate the rates of wound and neurologic complications and clinically significant heterotopic ossification, Brooker stage 3 and 4, with the modified Ollier transtrochanteric approach for the treatment of acetabular fractures. The study group comprised 94 consecutive patients (95 acetabuli) who had unstable acetabular fractures requiring ...
