Resection of Heterotopic Ossification and Didronel Therapy — Regaining Wheelchair Independence in the Spinal Cord Injured Patient

Abstract

Ankylosis of the joints secondary to heterotopic ossification in the spinal cord injured is not uncommon. Five patients had ankylosis of the hip and knee joints which limited their ability to function in their wheelchairs. They underwent eight resections to improve their functional capabilities. All patients were treated pre- and postoperatively with disodium etidronate (EHDP, DIDRONEL*). The average interval from injury to surgery was nine years nine months and the average interval from surgery to follow-up was two years three months. With clearly defined goals, proper patient selection, good pre- and postoperative management and intense rehabilitation combined with Didronel, optimum functional results were achieved.
