Abstract

PURPOSE
To review the results of resections of heterotopic ossification around the hip in patients with central nervous system injuries.
MATERIALS AND METHODS
Heterotopic ossification was resected in ten hips of eight patients and followed for at least one year. Average age was 38.1 years (range, 21-56 years). We reviewed the charts and the radiographs for overall patient function, location of the lesion, radiographic evidence of maturation and any recurrence. Heterotopic ossification was resected regardless of the result of bone scan.
RESULTS
All patients showed improved function. Three minimal recurrences and one moderate recurrence were identified at the last follow-up radiography, but the range of motion had not decreased due to recurrence.
CONCLUSION
Severe heterotopic ossification around the hip in patients with spastic paralysis was resected, and it was found that the range of motion was improved in all patients and that the chance of recurrence was minimal, even though the bone scan showed hot uptake on the bone scan.
