Abstract:
Objective:To discuss the effect of single low dose local radiotherapy and indomethacin to-gether in the prevention of recurrence of ectopic ossification around the elbow after resection.Methods:From Jun.2009 to Dec.2011,we performed excision of ectopic ossification around the elbow in 78 stiff elbows.For each case,we used both medial and lateral approaches,and we performed both anterior and posterior capsulectomies and removal of ectopic ossification.In the lateral approach,we started proximal-ly,the lateral supracondylar ridge of the humerus was exposed from the interval between extensor carpi radialis longus (ECRL)and triceps,and then distally passed the interval between ECRL and extensor carpi radialis brevis (ECRB).With the medial approach,after releasing the ulnar nerve,the pronator teres muscle origin was reflected from the medial epicondyle,and then the common flexor-pronator tendon was split longitudinally distally and the brachalis and the anterior portion of the flexor-pronator group were dissected off the anterior humerus.If there was forearm rotation dysfunction,we used extensive lateral ap-proach,the anconeus muscle was reflected from the ulna and the scar tissue and ectopic ossification around the proximal radioulnar joint were resected.The important structures,such as the lateral ulnar collateral ligament (LUCL)and the anterior part of the medial collateral ligament (AMCL),should be carefully protected,because they were important for the elbow stability.Anterior transposition of the ulnar nerve depended on the patients’condition.We performed low dose radiotherapy 4 hours before opera-tion,and we used indomethacin for 6 weeks after operation.In these patients,there were 46 males and 32 females,whose age averaged (35.8 ±7.9)years (16 -65 years).According to Hastings-Graham classification,there were 56 ⅡA,5 ⅡB,6 ⅡC and 1 1 Ⅲ before operation.Results:We followed up these patients for 26 months with an average of 24-36 months,all the patients improved their elbow func-tion,and no recurrence of ectopic ossification appeared except for 1 patient.For this patient,his elbow function was excellent,and according to Hastings-Graham classification,his ectopic ossification was of typeⅠ.Conclusion:Single low dose local radiotherapy and indomethacin together are effective in the prevention of recurrence of ectopic ossification around the elbow after excision.
