Complex elbow trauma, severe burn, or a closed head injury render patients at risk for developing heterotopic ossification around the elbow. When heterotopic ossification restricts elbow motion, some patients request surgical resection. We performed a systematic review of the literature to analyze improvement in elbow motion after resection of heterotopic ossification around the elbow. We found...

  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...

Endochondral ossification is very unique and complex biological event which is associated with skeletal development and tissue partnering. Genetic studies and gene-targeting approaches identified several transcription factors that play important roles in endochondral ossification. These transcription factors sequentially and harmoniously regulate each step of endochondral ossification, and cons...

Dendriform pulmonary ossification is a rare condition often diagnosed by either surgery or postmortem examination. We report a 43-y-old man with a history of nonproductive cough for 1 y. His physical examination was unremarkable. Chest computed tomography showed multiple bilateral micronodules in both lower lobes; however, the patient's pulmonary function was normal. Flexible bronchoscopy with ...

Heterotopic ossification is defined as the development of mature bone tissue outside normal bone. Osteomyelitis an infection-related inflammatory disorder bones. Although pressure sores accompanied by heterotopic have been reported, there no reports osteomyelitis occurring in proximity to ossification. Herein, we report a rare case after trochanteric sore reconstruction. We also emphasize impor...

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...

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...

We provide here unique data on elephant skeletal ontogeny. We focus on the sequence of cranial and post-cranial ossification events during growth in the African elephant (Loxodonta africana). Previous analyses on ossification sequences in mammals have focused on monotremes, marsupials, boreoeutherian and xenarthran placentals. Here, we add data on ossification sequences in an afrotherian. We us...

There is no agreement in the literature as to the time of the onset and progress of the vertebral column ossification. The aim of the present study was to determine the precise sequence of ossification of the neural arches and vertebral centra.Histological and radiographic studies were performed on 27 human foetuses aged from 9 to 21 weeks. It was found that the ossification of vertebrae commen...

Ossification of the posterior longitudinal ligament and ossification of the yellow ligament are the main causes of spinal canal stenosis. This article describes a case of ossification of the posterior longitudinal and yellow ligaments on the lumbar spine. The patient presented with gradually worsening left lower-extremity ache and pain. The deep tendon reflex was hyperreflexia in the lower extr...
