Heterotopic ossification: a review.

摘要: Heterotopic ossification is defined as the presence of lamellar bone at locations where normally does not exist. The condition must be distinguished from metastatic calcifications, which mainly occur in hypercalcaemia, and dystrophic calcifications tumours. It a frequent complication following central nervous system disorders (brain injuries, tumours, encephalitis, spinal cord lesions), multiple hip surgery burns. In addition to this acquired form, hereditary causes also exist, such fibrodysplasia ossificans progressiva, progressive osseous heteroplasia Albright's osteodystrophy. Although these conditions are extremely rare, they can provide useful information on physiopathology heterotopic ossification, thus lead novel causal treatment modalities. no trivial complication. A limitation range joint motion may have serious consequences for daily functioning people who already severely incapacitated because their original lesion. Increased contractures spasticity, pressure ulcers increasing pain further compromise patient's capabilities. Consequently, we feel that attention should paid pathogenesis particularly prevention disorder.
