The surgical treatment of heterotopic ossification at the elbow following long-term coma
JB Roberts and DG Pankratz
Nine cases of heterotopic ossification at the elbow in seven patients who
had a cerebral injury and prolonged coma were treated by excision of the
extra-articular bone bridge from the humerus to the ulna. The bridge was
either anterior or posterior, and did not involve the radius. The articular
cartilage in all elbows showed no significant evidence of degeneration in
spite of the prolonged immobility of the joints during the period of coma.
Two of the patients also had resection of heterotopic bone about the hip
joint which resulted in rapid reformation of bone. In all patients there
was restoration of satisfactory function in the elbow operated on without
reformation of bone. Follow-up was from ten months to 8.7 years.
