Objective: We aimed to find out the distribution of etiological factors in patients who had total hip replacement for coxarthrosis. Methods: The medical records of the 965 hips of 886 patients operated with total hip replacement between 2001 and 2012 in two separate arthroplasty clinics were analyzed by two separate senior surgeons. Each patient’s pre- and postoperative X-rays and demographic data such as gender, age, side and probable etiologic factors were noted. Results: Six hundred and eighty-four patients were women and 202 were men. The mean age were 62.7±14.3 (range: 16 to 91) in women, 58.8±17.1 (range: 25 to 91) in men. 52.1% of the surgeries were performed on the right side, 39% on the left, and 8.9% bilaterally. In women 36.2% of the cases were primary coxarthrosis, while the etiology was developmental dysplasia of the hip (DDH) in 43.5% of the cases, avascular necrosis in 10%, romatoid diseases in 7%, slipped capital femoral epiphysis in 5%, posttraumatic coxarthrosis in 3.9%, pathologic coxarthrosis in 1.9%, and Perthes sequel in 1.7%. In men, 24.4% of the cases were primary coxarthrosis, while the etiology was avascular necrosis in 21% of the cases, DDH in 17.6%, posttraumatic coxarthrosis in 16.8%, romatoid diseases in 10.9%, Perthes sequel in 4.2%, slipped capital femoral epiphysis in 2.5%, and pathologic coxarthrosis in 2.5%. The most common etiologic factor was DDH with a rate of 37.1%. Conclusion: Despite the heterogeneity of our study population, our results may reflect the distribution of coxarthrosis etiologies in Turkey. Developmental dysplasia of the hip appears to be the most frequent cause of coxarthrosis among the patients undergoing total hip replacement.
