Results: There were 16 prospective (36.4%) and 28 retrospective (63.6%) cases. The mean age was 45.07 years with maximum number of 39 (88%) patients in the age group of 21-60 years. Majority (77.3%) of the patients was males and 22.8% were females. Modified Merle d’Aubigne and postel (MDA) score was excellent in 77% patients, good in 13%, fair in 10%. Matta’s radiological score at final follow up was excellent in 54.55%, good in 36.36%, fair in 4.55% and poor in 4.54% patients. The average Modified Harris Hip score was 94 at final follow up in 44 patients. Patients with anterior column fracture had HHS of 96 at final follow up; posterior wall fracture patients had average HHS of 92 at final follow up. Two patients had complications. One patient had femoral head fracture along with fracture of posterior wall developed AVN and also had subsequently Secondary OA with post operative subluxation of femoral head. Thus three complications were seen in this patient. Another patient with fracture dislocation with fracture of posterior wall developed AVN and subsequently secondary OA 5 year after surgery. No patient developed sciatic nerve injury post operatively. None of patients developed postoperative sciatic nerve palsy. No patient died during treatment or follow up. Conclusion: Open reduction and internal fixation as a gold standard for acetabulum fractures which is indicated with excellent to good results in majority of the patients as assessed by Modified Merle d’Aubigne score, Modified Harris hip score and Matta Radiological score with minimal complications at final follow up.
