%X <b>Purpose:</b> This paper aims to evaluate the postoperative outcomes of femoral trochanteric fractures with fracture lines extending to the base of the femoral neck (Type 2-3 fractures), treated with intramedullary nails featuring double screws into the femoral head. <b>Methods:</b> A multicenter prospective study enrolled 225 patients with proximal femoral fractures. Type 2-3 fractures were classified based on the Area classification using 3D-CT. We compared surgical outcomes among three types of short femoral nails with double lag screws. <b>Results:</b> Type 2-3 fractures accounted for 28.4% of cases. Among them, 79.7% were treated with nails incorporating double lag screws. No significant differences were found in failure rate, reduction quality, or operative parameters among different implant types. <b>Conclusion:</b> Good postoperative outcomes were achieved in Type 2-3 fractures using intramedullary nails with double screws into the femoral head, regardless of implant brand.
