Background. Superior cut-out of a lag screw remains a serious complication in the treatment of trochanteric or subtrochanteric @entity174 and it is related to many factors: the type of @entity174 , @entity170 and the stability of @entity174 reduction. Little is known about the outcome after revision surgery for complications of the gamma nail. We assessed the outcome in @entity1 who had revision surgery because of lag screw's cut out after gamma nailing for a @entity173 .Material and Method. We present a study of 20 consecutive @entity1 who underwent treatment after 20 cut-out of the lag screw    xation of a @entity173 with Gamma Locking Nail from September 2004 to November 2010. In 16 @entity1 hip prothesis was performed, in 1 the removal of the implant and in 3 the reosteosynthesis. We reviewed 13 @entity1 : 10 total hip arthroplasty, 2 endoprothesis and 1 reosteosynthesis of nail and lag screw (mean follow up: 26 months, mean age: 73 years old), 7 @entity1 died. @entity1 were reviewed retrospectively by an independent observer. Clinical evaluation was performed, Oxford score and Harris Hip score were measured. X-Ray examination was performed after a minimum of 12 months of follow up.Results. Mean Harris Hip Score mean was 67 and mean Oxford score was 32 in hip prothesis group (12 @entity1 ). We had several complications, Implant-related complications were: 2 ipometria > 2cm, 2 recurrent @entity572 (1 reoperated), 4 persistent thigh @entity158 . In only 4 @entity1 none complications were observed. Another @entity1 ,   who had been subjected to reosteosinthesis, obtained better results ( @entity11339 :95, Oxford score:45) but with a 2 cm ipometria and occasional @entity158 in the thigh.Conclusion. Cut out after gamma nail is consequent to biological or mechanical causes. Treatment of this complication is hip prosthesis ( @entity572 ), reosteosynthesis of the lag screw and/or the nail and the removal of the implant. Conversion to total/parzial hip arthroplasty may be a demanding operation with a higher complication rate respect to the standard, while reosteosynthesis is possible in selected @entity1 and early cutting out.
