BACKGROUND Even though heterotopic ossification (HO) is most often asymptomatic in patients after total hip replacement (THR), it remains a serious problem in orthopaedics as it is observed in nearly all operated patients. MATERIALS AND METHODS The article presents a pre- and post-operative retrospective analysis of heterotopic ossification based on radiographic evidence. The study involved 7...

We report the first case of early gastric cancer just above a heterotopic pancreas for which the differential diagnosis was carcinoma arising from heterotopic pancreas. Routine upper gastrointestinal endoscopy in an 83-year-old man with sigmoid colon cancer revealed a gastric cancer in the lesser curvature of the antrum. Endoscopic ultrasonography (EUS) for evaluating the depth of tumor invasio...

heterotopic pregnancy is a rare event in natural conception cycles. the prevalence of heterotopic pregnancy is known to be increasing in part due to more precise diagnostic techniques and widespread use of of assisted reproductive technology. a case of an incidental heterotopic pregnancy diagnosed at 10 weeks of gestational age is reported here in which laparotomy was scheduled and right salpin...

Heterotopic ossification is defined as bone formation in nonosseous tissues. Heterotopic ossification usually occurs in trauma such as fractures and surgical procedures. Heterotopic ossification of the hip, for example, is the most common complication of total hip arthroplasty (THA). It can occur in as many as 53% of THA patients, and it causes postoperative disability from pain and limited ran...

Heterotopic pancreatic tissue of the stomach is a rare condition. The author herein reports three cases of heterotopic pancreatic of the stomach. The three cases were found in the 8,154 gastric specimens (biopsy 6,122 cases, gastrectomy 2,032 cases) of our pathology laboratory; the frequency was 0.04%. The first case was a 57-year-old woman who presented with epigastralgia. Endoscopic examinati...

AIM To present the incidence of heterotopic ossification after the use of recombinant human bone morphogenetic protein-7 (rhBMP-7) for the treatment of nonunions. METHODS Bone morphogenetic proteins (BMPs) promote bone formation by auto-induction. Recombinant human BMP-7 in combination with bone grafts was used in 84 patients for the treatment of long bone nonunions. All patients were evaluat...

Purpose One of the local factors contributing to the formation of heterotopic ossification includes bone debris generated during the surgery. This risk can be partially nullified by use of saline wash. Our research aim was to ascertain if extensive intraoperative lavage can reduce the incidence and severity of heterotopic ossification in primary total hip arthroplasty. Materials and Methods A...

fibrodysplasia ossificans progressiva (fop) is a rare hereditary connective tissue disease characterized by the progressive ectopic ossification of ligaments, tendons, and facial and skeletal muscles throughout life. symptoms begin in childhood as localized soft tissue swellings. immobility and articular dysfunction appear with involvement of the spine and proximal extremities. the temporomandi...

BACKGROUND Heterotopic ossification (HO) is a rare and potentially detrimental complication of soft-tissue trauma, amputations, central nervous system injury (traumatic brain injuries, spinal cord lesions, tumors, encephalitis), vasculopathies, arthroplasties and burn injury, characterized by lamellar bone growth in non-osseous tissues such as the muscle and the joint capsule. Heterotopic ossif...

Background Complications caused by heterotopic ossification are a common concern after orthopaedic surgery of the elbow. Little effort has been directed at establishing best practices of management of heterotopic ossification in the elbow, in stark contrast to that in the hip. A survey was distributed to all orthopaedic residency programs in the United States to understand current management of...
