We report a case of bony ankylosis of the knee secondary to severe and extensive heterotopic ossification over 9 years after primary total knee arthroplasty in a 71-year-old woman.
True ossification of the face spaces is a very rare clinical entity. We present a rare case of unilateral ossification of infratemporal space the in an 11-years old male with swelling in the right temporal and orbital area. His medical history was unremarkable. Radiographic evaluation with spiral CT scan revealed separated ossified particles inside of infratemporal space. After 2 separate proce...
The deposition of amorphous calcium salts within the soft tissues is variously called mineralization or calcification. Two forms of calcium salts may be found in the soft tissues: calcium pyrophosphate dihydrate and calcium hydroxyapatite. If bony trabeculae are discernible within the mineralized focus the term ossification is used, sometimes prefixed with the terms ectopic or heterotopic. Ther...
Heterotopic ossification (HO) is the pathologic formation of bone separate from the normal skeleton. Although several models exist for studying HO, an understanding of the common in vitro properties of cells isolated from these models is lacking. We studied three separate animal models of HO including two models of trauma-induced HO and one model of genetic HO, and human HO specimens, to charac...
We present nine patients (five men and four women) who underwent surgical excision of clinically significant heterotopic ossification at the elbow. They also received perioperative radiation therapy using total doses between 600 and 1000 cGy. Five received fractionated radiotherapy, with two fractions of 500 cGy applied on the first two postoperative days, and the remaining four were irradiated...
Although the incidence of minor heterotopic ossification is probably higher than what is usually expected, severe heterotopic ossification (HO) is an extremely rare event following total knee replacement surgery. We present the case of a 66-year-old woman who initially had achieved an excellent range of motion following bilateral uncemented rotating platform total knee replacement, before prese...
Fibrodysplasia ossificans progressiva (FOP) is a rare autosomal dominant disorder characterized by postnatal progressive heterotopic ossification of the connective tissue and congenital malformation of the big toes. We report on a nine-year-old girl with clinical and radiological features of FOP. She was born with bilateral hallux valgus and at the age of nine presented an indurate mass in the ...
