We review our results of 17 patients, who had early excision 5 months (3-8 months) of post traumaticHeterotrophic ossification (HO) of elbow,followed by medical treatment with indomethacin to prevent recurrence, in our study. The average age group of our patients is 24 years (15-38). There were 12 males and 5 females. The patients were followed up for average of 58 months (38-90 months). The mean preoperative Mayo Elbow Performance Score (MEPS) was 63(40-80), and the mean MEPS core at final follow up is 90(75-100). According to MEPS, 13 patients had excellent result and 4 patients had good result. All the patients were asymptomatic at the time of final follow up. One patient with intra operative ulnar nerve injury recovered partially, and remained with some disability at final follow up. Patient with pre operative median nerve palsy recovered completely at 3 months post operatively.
