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...

The processes of ossification sequences are poorly investigated for birds in general, even for domestic and experimental species and when it comes to the waterfowl it is almost negligible. Such sequences constitute a rich source of data on character evolution, and may even provide phylogenetic information. A pre-hatch developmental study on ossification sequences of axial and appendicular skele...

BACKGROUND Delayed fetal skeletal ossification is one of the known complications of maternal diabetes. OBJECTIVE The present study was designed to evaluate the protective role of petroleum ether extract of Cissus quadrangularis (PECQ) on diabetes-induced delayed fetal skeletal ossification. MATERIALS AND METHODS Female Wistar rats were rendered diabetic with streptozotocin (STZ, 40 mg/kg, i...

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....
