RESUMO
OBJECTIVE: To assess the efficacy and prognostic factors of preoperative radiation therapy in patients of elbow arthrolysis. METHODS: From October 2008 to September 2010, 43 patients with heterotopic ossification (HO) history at elbow were studied retrospectively. Radiation therapy was given in single fraction of 8 Gy within 1-4 h pre-operation. The elbow HO classifications at preoperation and the last follow-up were analyzed and their efficacy and related prognostic factors evaluated. RESULTS: The median follow-up period was 34 (23.24-46.26) months. The elbow function of 19 (44.2%) cases returned to normal. One case was ineffective. Only one case had vulnus swelling. Graham and Hastings HO classification scores were significantly different between pre-operation and the last follow-up (Z = -5.899, P = 0.000). Logistic analysis showed that age and time between diagnoses and treatment had a significant influence of elbow HO. CONCLUSION: Preoperative radiation therapy of 8 Gy within 1-4 h of elbow arthrolysis is both safe and effective. And greater age, milder wound and longer time between diagnoses and treatment have better outcomes.
