  The Intertan nailing system is a fourth-generation cephalomedullary nail designed for stable fixation of intertrochanteric and subtrochanteric fractures of the proximal femur. Unlike conventional single-screw nails, Intertan uses two integrated cephalocervical screws within a single construct, providing superior control of both axial load and rotation. The larger lag screw enables controlled fracture compression, while the smaller antirotation screw locks with it to prevent femoral head rotation and reduce cut-out risk. Its anatomically contoured trapezoidal nail improves proximal femoral fit and rotational stability within the canal. These design features make Intertan particularly useful in unstable fracture patterns and osteoporotic bone, where mechanical failure can be catastrophic. Clinical studies consistently report lower rates of cut-out and peri-implant fractures compared with single-screw systems, with similar long-term union and functional outcomes. Although implantat...
