BACKGROUND AND OBJECTIVES: One of the most difficult problems in @entity5 surgery is the treatment of @entity530 , particularly those in the periacetabular region. This retrospective study serves to analyze clinical and functional outcome of the new surgical technique of hip transposition. @entity1 AND METHODS: Sixty-two @entity1 were analyzed ( @entity511 15, @entity2828 or PNET 26, @entity421 14, synovial cell sarcoma 2, others 5) and clinical, oncological, and functional outcome were evaluated. RESULTS: The surgical procedure focused on hip transpositions Type I (n = 9), Type IIa using the MUTARS attachment tube (n = 36), and Type IIb using the MUTARS attachment tube with a proximal femur endoprosthesis and bipolar cup (n = 17). In 53 @entity1 (85.5%), wide margins were achieved. The 1- and 5-year overall survival rates were 96.4% and 80.5%, respectively. The 5-year (10 years) overall survival was 82.1% (82.1%) for @entity2828 , 60.1% (40.6%) for @entity421 , and 92.3% (46.2%) for @entity511 . @entity130 were observed in 14 cases, @entity281 in 20 cases. The mean Musculoskeletal Tumor Society (MSTS) score was 62% (18.6 Pts    3.73). CONCLUSION: Hip transposition can be considered as an easy and safe surgical procedure to employ in order to achieve good functional outcome in periacetabular @entity5 .
