The aim of this study was to evaluate the clinical and radiological results of treatment and quality of life, and impact of surgical approach in patients after arthroplasty using anatomical stem ABG II in the Department of Orthopaedics and Trauma Regional Hospital. St. Luke in Tarnów of years 2008-2011. The material consisted of 68 patients operated using a Proxima stem (surgical approaches; anterolateral--34 cases, posterior lateral---34 cases similarly). The average age was 62.2 years. Patients stayed in the hospital an average of 8 days. Term follow-up was determined after 6 weeks, 3 months and then once a year. Postoperative results were evaluated using the scale: Harris and WOMAC NRS. X-rays were evaluated for setting and migration of the prosthesis components. In assessing patients with HHS to scale achieved 73.5% of very good and good. Compared to the pre-operative assessment resulted in a significant improvement in mobility of the hip after arthroplasty. According to the standardized WOMAC extended the average score of treatment was 77.0 points. During the study showed significant reduction in pain intensity after surgery. Average NRS score before surgery was 6.4 points and 1.4 points after surgery. In the material appropriate settings were 51 and 17 axial axis of the prosthesis. No effect on clinical outcomes set in the HHS and WOMAC scales. There was no effect on the results of surgical treatment.
