Abstract

Heterotopic ossification (HO) is a frequent complication associated with spinal cord injury and can lead to significant problems during rehabilitation. Surgical resection of HO could be applied to patients who do not respond to conservative treatment. To reduce the risk of recurrence after the operation, radiation therapy and NSAID or bisphosphonate administration may be utilized. We report the case of a 48-year-old male with a T3-sparing spinal cord injury who underwent successful treatment of immature HO in the iliacus muscle with a combination of surgical resection, radiation therapy, and NSAID administration.

  Fig. 1 (A) There is increased irregular and faint change of density on pelvis AP simple X-ray at intertrochanter area. (B) Increasing tubular shape density of isotope from internal area of anterior superior iliac spine to lower area of lesser trochanter by Bone scan. (C) From oblique 3D image, there is Immature heterotopic ossification without the invasion of hip joint area.
