Objective: We aimed to investigate the clinical outcomes of femoroacetabular impingement syndrome (FAIS) cases who underwent reconstruction with safe hip dislocation. Material and Methods: Between 2006 and 2009, 13 male cases diagnosed with FATS, whose anterior impingement sign was positive without hip dysplasia were included in the study. Posterior impingement test was positive in five cases. Mean age was 39.3 years (range 32-47). Pre- and post-surgical radiological investigation included hip antero-posterior and false profile x-rays in all cases. In the preoperative period, all cases had femur type impingement except one case with acetabulum type impingement. Radiological investigation revealed cross-over sign and posterior acetabuler wall insufficiency in all cases. Harris hip scoring system was used for functional asseessment. Surgical dislocation was performed as described by Ganz et al. Trochanteric osteotomy line was fixed with two cannulated screws. Results: In all cases femoral impingement cause was eliminated during the operation. Only one case had Pincer lesion, complete degeneration and dissociation that required Labrum resection. There was no nonunion following trochanteric osteotomy. The preoperative mean Harris hip score in 13 cases changed from 63.24 (range 55-70) to 89.75 (range 72-98) two years after the operation. Statistical analysed including the Wilcoxon Signed Ranks test revealed highly significant (p<0.001) differences between pre- and post-operative Harris scorings. Postoperative impingement tests were negative in all cases. Conclusion: Surgical treatment of cases with FAIS with safe hip dislocation was promising. We suggest that safe surgical dislocation is a proper method for treatment as the complication/clinical improvement ratio is in favor of clinical improvement in cases with FAIS.
