Heterotopic ossification is the calcification of the soft tissues with increased calcium accumulation in that tissue. The imaging characteristics are well defined because it is a well-known documented entity. However the metabolic characteristics are less well known due to the relatively recent development of the PET/CT modality. Previous reports in tissues elsewhere the body confirms that the ...

Heterotopic ossification (HO) is defined as pathological bone formation in soft tissues, for example in muscles, where physiologically there is no osseous tissue present. It is one of the most common complications of total hip joint replacement surgery. A wide variety of risk factors for heterotopic ossification have been identified to date. Almost 90% of total hip arthroplasty patients are at ...

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...

Introduction The term heterotopic ossification refers to the aberrant formation of mature, lamellar bone in nonosseous tissue. Translated from its Greek (heteros and topos) and Latin (ossificatio) etymologic origins, heterotopic ossification can be literally defined as "bone formation in other location." The first written account of heterotopic ossification describes the treatment of symptomati...

Heterotopic ossification is the formation of new bone in an abnormal location. It is usually seen following central nervous system disorders, including spinal cord injury, traumatic brain injury, encephalitis, and burn and trauma. Heterotopic ossification in post-stroke hemiplegia is rare; the reported incidence is 0.5-1.2%. It usually occurs on the paretic side of hemiplegic patients. We prese...

progressive osseous heteroplasia is a rare inherited disease that begins with skin ossification and proceeds into the deeper connective tissues. the disease should be distinguished from other genetic disorders of heterotopic ossification including fibrodysplasia ossificans progressiva (fop) and albright hereditary osteodystrophy (aho). we report a case of progressive osseous heteroplasia in a t...

Our study was designed to compare the effect of indometacin with that of a placebo in reducing the incidence of heterotopic ossification in a prospective, randomised trial. A total of 121 patients with displaced fractures of the acetabulum treated by operation through a Kocher-Langenbeck approach was randomised to receive either indometacin (75 mg) sustained release, or a placebo once daily for...

conclusions radiological findings pleaded for a pituitary stone, but calcified adenomas in women, and calcified craniopharyngioma in the pediatric case could not be excluded, as our three patients were not operated on. introduction pituitary stone or pituitary calculus is a scientific enigma characterized by a large calcification in the pituitary sella. it can be discovered incidentally or in a...

INTRODUCTION Heterotopic ossification is a rare complication of musculoskeletal injuries, characterized by bone growth in soft tissues. Percutaneous antegrade intramedullary nailing represents the 'gold standard' for the treatment of femur shaft fractures. Minor bone growth is frequently seen around the proximal end of reamed femoral nails (so-called 'callus caps'), which are asymptomatic and l...

RATIONALE Retrograde femoral nailing was one of the most important treatment means for distal femoral shaft fracture. However, studies regarding heterotopic ossification of the patellar tendon after retrograde intramedullary nailing for distal femoral shaft fracture are limited. We herein present a rare complication, namely heterotopic ossification of the patellar tendon, after retrograde intra...
