Multifactorial refractory heterotopic ossification.
Ectopic bone formation or "heterotopic ossification" can follow surgery, trauma, or neurologic injury, but the process is usually self-limited, localized to the site of injury, and responds to surgical treatment when necessary. Aggressive, systemic forms of heterotopic ossification exist that generate lesions that often resist surgical treatment and produce a high rate of recurrence. These entities typically manifest during infancy as genetic syndromes such as fibrodysplasia ossificans progressiva or progressive osseous heteroplasia. The authors describe a case of aggressive, systemic heterotopic ossification in an adult that followed a motor vehicle accident and multiple surgeries. The patient developed a large nonhealing wound around a focus of ectopic bone. Skin grafts failed as a result of the recurrence of ectopic bone, and the patient eventually required aggressive debridement and delayed rotational flap closure. A brief review of the clinical features and surgical treatment of heterotopic ossification is outlined.
