Introduction: We present only the difficult cases of THR in high dislocated hip: grade III DUNN, type IV CROWE, or stage C and D EFTEKHAR; and also our classification of the femoral displasias: 1. Stage I vice of the femoral head associated with type III Crowe, Dunn III, Eftekhar stage B or C 2. Stage II femoral canal eliptique, supplementary vice of torsion of the diaphysis, metaphysis associated with type III Crowe, degree III Dunn, Eftekhar C or D, witch could bee operated without diaphyseal osteotomy by trochanterotomy 3. Stage III important torsion of the diaphysis large medullar diameter of the metaphysis perpendicular to the large diameter of the diaphysis canal Excellent indication for triple osteotomy femoral 4. Stage IV caricaturized

Materials and Methods: We intend to compare here the preliminary results of two surgical techniques: I) cemented prosthesis implanted by trochanterotomy, with femoral shortening osteotomia and trochanteroplastia versus II) femoral subtrochanteric triple osteotomia of shortening, with correction of a fore-existent valgum and derotation by using a non-cemented femoral component.

Results: I) between 1993 – 2001 we have operated 61 patients, average age 42. Technically, we have implanted cemented prostheses by trochanterotomy and femoral shortening osteotomy, followed by Kerboull-Postel trochanteroplastia. The nonunion of greater trochanter, considered as failed cases, determined us to adopt the technique of triple femoral osteotomy, using a non cemented femoral component functioning as a centromedulary nail. II) Between 2001 – 2003, more other 6 cases have been operated by the technique of triple femoral osteotomy. We have pre- and postoperative clinically evaluated our patients by Merle D’Aubigne-Postel criteria.

Conclusions: These results are preliminary, we have not had enough surveillance time for uncemented femoral prostheses, but this technique seems us attractive though femoral complications have not yet been noticed.
