Background: Internal fixation is the primary treatment choice in younger age group suffering from fracture neck femur. But rate of failure of internal fixation in neck of femur fractures is high despite all measures. Fixation can be done by using three cannulated hip screws or by dynamic hip screw with or without a derotation screw. The outcomes of fracture neck of femur in young patients treated with Dyanamic Hip Screw (DHS) with a de–rotation were analyzed.

Materials and methods: The study was conducted on 54 patients were selected based on pre–determined eligibility criteria. The dynamic hip screw was inserted with a standard technique by means of a straight lateral incision on the lateral aspect of the thigh and hip.

Result: shows effect of dynamic hip screw with derotation screw is good.

Conclusion : Osteosynthesis of intra–capsular femoral neck fracture with dynamic hip screw with derotation screw is good.
