Inter–trochanteric fracture is commonly seen in elderly age group which is usually associated with osteoporotic bones. In general fracture fixation done with DHS plate using 16mm threaded lag screw. With this fixation in osteoporotic bone have high cut–out incidence. To overcome this problem we used 32mm threaded lag screw. Its a prospective study has been conducted at R.N.T. MEDICAL COLLEGE, UDAIPUR, RAJASTHAN, during the period from JAN 2015 to December 2016. 40 elderly patients (>60 years) with Intertrochanteric fractures who met the inclusion criteria treated with  dynamic hip screw fixation using 32mm threaded lag screw were selected for the study. During this study the mean union time was 13.54 weeks. The mean   time for protected weight bearing was 9.73 days and mean time for patients to walk without support in cases was 13.2 weeks. There were .59 cm mean limb length shortening seen in final post operated follow up. No incidence varus collapse or superior screw cut out was observed in any of the patients in spite of weight bearing ambulation from the early postoperative period. Fixation of inter–trochanteric fracture femur with dynamic hip screw using 32mm threaded lag screw is likely to reduce the incidence of complications of fixation like implant failure in spite of early weight bearing, like screw cut, AVN, malunion, in elderly patients with intertrochanteric femur fractures.
