The "Z" and “Z” light trochanteric nailing was primarily developed for the surgical treatment of trochanteric fractures and of some cases of femoral neck fractures. The system combines the biomechanical advantages of the intramedullary nailing and the traditional dynamic hip screwing. Due to its wide length- and diameter ranges it can offer an excellent surgical solution for the upper third femur fractures, and even for its combinations with diaphyseal fractures. The essential component of the system is a dynamic hip screw that is inserted into the femoral neck. The hip screw is able to compress the fracture, but it has a dynamic behavior during the healing. A fixing screw, which is inserted in the nail, ensures both the dynamization and the prevention of the rotation of the hip screw after the surgery. The aiming device is made from a radiolucent material.

The anatomical fit provides easy insertion. The distal end of the nails has an oval hole for dynamization. For slim bones, nails with smaller diameter i.e.
