The proximal femoral nail is the most common device used to treat unstable intertrochanteric fractures (ITFs) (AO/OTA 31-A2 and A3) in the geriatric population. However, there is lack of radiological parameter to evaluate the entry point; hence, this study reports a new radiological parameter to evaluate the entry point of the nail. Besides, other risk factors were also examined. The series included 20 cases treated with proximal femoral nail. Those patients were emulated dependent upon clinically What's more radiologically with pelvic anteroposterior Furthermore hip parallel perspectives during 4weeks ,8weeks, 3 months,6 months postoperatively. Demographic data, radiological parameters, and side-difference of the separation from those piriformis fossa of the more terrific trochanteric tubercle in the anteroposterior perspective (dPG) were compared the middle of the union Furthermore disappointment gatherings. Student's t test, χ 2 test, and different logistic relapse were utilized within those measurable analyses. Normal agdistis may be 63. The etiology of the fractures might have been 4 RTA patients (20%) Also 16 tumbling patients. The AO/OTA arrangement framework might have been utilized. There were 9 sort 31-A2 fractures (45%), this ponder exhibited that TAD>24mm , DPG>7mm expanded those danger about disappointment after nailing Previously, flimsy intertrochanteric fractures ,and it might have been An critical predictor from claiming disappointment. This recommended another radiological parameter, DPG will reflect the geometry of the more excellent trochanter following nailing , we discovered that expanded DPG will be connected with expanded danger from claiming disappointment. This ponder gives extra confirmation demonstrating that sex and tad have huge impacts on the results about flimsy ITFs following nailing. Moreover, the recently news person radiological parameter, dPG, could be used to anticipate those disappointment for ITFs approached utilizing proximal femoral nails.
