Abstract: Introduction Present study aimed to evaluate the effect of position of the screw on the failure of fixation in intertrochanteric femoral fracture treated by dynamic hip screw. Materials & Methods The study was conducted on 32 patients undergoing fixation of intertrochanteric fractures with DHS. The fracture reduction was assessed according to the Garden alignment index (GAI). The position of the screw was determined by the tip apex distance. The location of the screw was also recorded according to the ratio method described by Parker. The patients were divided in two groups taking into consideration the TAD less (Group A) or more (Group B) than 25 mm. For both groups, we compared quality of reduction, number of patients with cut-out failure and Harris hip score. Data was analysed using SPSS ver 21. Results No statistical differences were observed between two groups with regards to the patients age, gender, type of fracture, Singh index, GAI and Harris hip score on the final follow-up. However, the lag screw was placed in the femoral head more inferiorly (p
