PURPOSE OF THE STUDY @entity1743 ( @entity1743 ) represents a mechanical conflct between acetabulum and proximal part of the femur. This disorder may gradually result in the development of the @entity570 . @entity1743 may be caused by an acetabular retroversion, rarely by coxa profunda or by asphericity of the femoral head and missing femoral head-neck offset respectively. However, a combination of both conditions is the most frequent. Before @entity1743 treatment was adopted as a standard technique for hip preservation at our department, detailed cadaver studies of the vascular anatomy of the hip were performed and the relevant literature was reviewed. The aim of this study was to assess the effiiency of hip preserving surgery in relation to the technique used. We hypothesized that surgical intervention helped to alleviate @entity158 and improve hip function. MATERIAL AnD METHODS In the period from October 11, 2005 to June 30, 2012, a total of 168 @entity1 (190 @entity572 ) had surgery for @entity1743 . After we met exclusion criteria, 83 @entity572 were treated by @entity572 ( @entity572 ) and 17 undergoing anterior minimally invasive surgery (AMIS). The minimum follow-up was 12 months, with an average of 3 years and 4 months, and a range of 12 months to 7 years and 8 months. The subjective evaluation by the @entity1 and the functional hip assessment were based on the Western Ontario and McMaster Universities Arthritis Index (WOMAC) and the non-Arthritic Hip Score (nAHS) questionnaires. To assess the effciency of the techniques, the pre- and post-operative scores were compared in each group ( @entity572 group, n=83; AMIS group, n=17). A comparison of pre- and post-operative data was also made for the groups joined together to evaluate the benefi of surgery as such in @entity1743 treatment. The results were statistically analysed using the Wilcoxon test for paired samples; the level of signifiance was set at 0.05. RESULTS There was a statistically signifiant increase in the scores obtained after surgery, as compared with the pre-operative data, in the @entity572 and AMIS groups and in all @entity1 evaluated together. Hip survival without the necessity of conversion to total hip replacement was 96.4% (80/83 @entity572 ) in the @entity572 group and 94.1% (16/17 @entity572 ) in the AMIS group. no serious complications were recorded. DISCUSSIOn The rate of failure in the surgical treatment of @entity1743 in our @entity1 was in accordance with the literature data, as was the number of the @entity1 requiring conversion to total hip replacement. Also the other results were comparable with those of relevant studies. COnCLUSIOnS Hip preservation surgery is an issue which has slowly been gaining consensus although opinions on it, including @entity1743 surgical treatment, still vary. As @entity1743 is a condition leading to degenerative changes in the hip, it is important to pay attention to a thorough diagnostic evaluation and a correct, though often long-term, therapy. key words: femoroacetabular impingement syndrome, surgical treatment.
