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...

An evaluation was made of the ossification level of the metacarpal and phalangeal bones in human foetuses of both sexes from the 4th to the 9th month of gestation. Our results indicate that ossification of phalangeal bones 1 to 5 always started at the distal end of the phalanx and endochondral ossification prevailed in the proximal phalanx of the thumb.

Long bone development depends on endochondral bone formation, a complex process requiring exquisite balance between hypertrophic cartilage (HC) formation and its ossification. Dysregulation of this process may result in skeletal dysplasias and heterotopic ossification. Endochondral ossification requires the precise orchestration of HC vascularization, extracellular matrix remodeling, and the re...

Heterotopic ossification is a common complication of numerous procedures, including abdominal operation, but traumatic perforation by such ossification is extremely rare. A 45-year-old man suffered traumatic perforation of the jejunum by ossification in a laparotomy scar. The diagnosis was made only at operation. The calcified mass was completely excised and the patient made a smooth recovery. ...

During a routine faculty prosection of the head and neck region of an adult female cadaver, a partial ossification of the falx cerebri was found. Ossification of other dural areas or regions of the body were not found. In addition, the brain and remaining organs appeared to be grossly normal. Reports of partial ossification of the falx cerebri are still rare and while certain pathologies such a...

Heterotopic ossification is characterised by the periarticular deposition of ectopic bone. It typically occurs after trauma, neurogenic injury, or congenital causes. Idiopathic heterotopic ossification has been rarely reported. A patient who developed idiopathic heterotopic ossification in the intensive care unit without any known predisposing conditions is presented.

BACKGROUND This study describes reference data for L3 vertebra and its 3 ossification centers at varying gestational ages. MATERIAL AND METHODS Using CT, digital-image analysis and statistics, the growth of L3 vertebra and its 3 ossification centers in 55 spontaneously aborted human fetuses aged 17-30 weeks was examined. RESULTS Neither sex nor right-left significant differences were found....

Background and Aim: Forensic age estimation of living individuals is a recent focus of scientific interest. Ultrasonographic examination of the hip is a safe and cost-effective method for assessment of skeletal age. Ultrasonography of the iliac bone apophysis and distal radial epiphysis is a useful and highly acceptable tool for bone age determination. The purpose of this study was to determine...

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...

Introduction: Heterotopic ossification is defined as the formation of trabecular bone that forms outside the normal sites of the skeletal structure, materializing in soft tissue where it does not usually exist. Methods/Case Report: This is a case report of a 27-day-old baby with a diagnosis of DiGeorge syndrome who developed heterotopic ossification on the dorsum of his right hand. Discussion: ...
