Abstract

Purpose: To evaluate the late results of the patients undergone total hip replacement surgery for hip dysplasia, implanting acetabular component more proximally than anatomic acetabular center. Patients and methods: In 1997-2004 in the Red Cross Hospital, (later VUHSK CF) hospital 85 hip replacement surgeries for patients with I-IVº hip dysplasia were performed by implanting acetabular component more proximally from anatomic acetabular center. This method was used to perform surgeries to 83 patients (17 men – 18 hip joints, 66 women – 67 hip joints). Prior to the surgeries, the patients responded to the Harris questionnaire on the condition of their hip joints. An average response rate was 42.1 (29- 62) point. In February and May 2013 having regard to the Harris questionnaire and objective tests the late results of treatment were successfully evaluated for 44 (53.01%) patients. Results: The evaluation of the patients’ responses to the Harris questionnaire established the average of 61.7 (26-88) points. Conclusion: Based on our findings, more proximal positioning of the acetabular component from the anatomic acetabular center seeking a more anatomic position without lateral displacement is one of the surgical options for selected patients with hip dysplasia.
