Myositis ossificans associated with pressure sore: a case report
Abstract
- Extraskeletal bone-forming lesions are myositis ossificans, fibrodysplasia(myositis) ossificans progressiva, and extraskeletal osteosarcoma. It is of paramount importance to clearly distinguish these lesion from extraskeketal osteosarcoma. Myositis ossificans, by far the most common among these lesions, is a benign, ossifying process that is generally solitary and well circumscribed. It is found most commonly in the musculature, but it may also occur in other tissue, especially in tendons and subcutaneous fat. It occur as the result of various kinds of soft tissue injury(surgical scars, burns, dislocation of joints etc.) and also observed in patients with tetanus, in paraplegics secondary to traumatic spinal injury. Although there is general agreement that myositis ossificans is a nonprogressive benign process without nerplastic potential, its pathogenesis is still poorly understood.We experienced a myositis ossificans associated with chronic, extensive pressure sore in patient with paraplegia secondary to spinal injury.
