Abstract
STUDY DESIGN: Retrospective chart review. OBJECTIVES: Heterotopic ossification (HO) affecting the hips is a common complaint of patients suffering traumatic spinal cord injury. However, the incidence of HO of the shoulder is considerably rare. In this context, we report on our results of 13 patients with a total of 21 cases of shoulder HO and single-dose radiation therapy. SETTING: Department of Spinal Cord Injury and Department of General and Trauma Surgery, BG-University Hospital Bergmannsheil Bochum, Ruhr-University Bochum, Germany. METHODS: The study group consists of 12 male and 1 female patient with a mean age of 55.5 years (range from 24 to 81 years; s.d.=14.5). Primary outcome measures were defined as the number of HO relapses and the number of side or adverse effects in relation to the radiation therapy. RESULTS: At the time of latest follow-up during hospitalization, the mean shoulder flexion was 92.1° while mean abduction was 94.5°. The average external rotation was 26.4°. No HO recurrence occurred and none of the patients suffered any adverse effects related to radiation therapy. CONCLUSIONS: In conclusion, single-dose radiation therapy in the treatment of shoulder HO due to spinal cord injury is an effective and reliable method, although the risk of secondary side effects related to the radiation therapy remain unknown.
