We studied 60 intertrochanteric fractures of the femur fixed with Dynamic Hip Screw (DHS). There were 10 cases (16.7%) with cutting-out of device through femoral head and neck. Stable fracture pattern, postero-inferior and central position of screw in the femoral neck and head produced high percentage of good result, whereas anterior or superior position of screw produced higher incidence of cut-out. We found osteoporosis and distance of screw tip to subchondral bone to have no influence on the final outcome.
