For shaft fractures in combination with trochanteric fractures the long version of AFTron nails is available. The nail is combining many of the features of a dynamic hip screw system and an intramedullary nail. Three different neck-shaft angles are available for lag screw insertion to accommodate various femoral neck anatomy. AFTron nail provides the surgeon the choice of using the lag screw in combination with the compression screw or to insert the lag screw in conjunction with the anti-rotation screw.
The load of the femoral head is transferred from the lag screw into the nail shaft in order to allow fast fracture healing. The lag screws are grooved to allow the set screw to fit into the same and to allow sliding of the lag screw to the lateral side of the fracture for dynamic bone compression. The set screw also avoids rotation and medial migration of the lag screw. In appropriate cases a 5.5 anti-rotation screw can be used in combination with the lag screw.
Distal locking screws with 5.0 diameter with a self-tapping tip facilitates easier and faster insertion. The distal locking screw is provided to stabilize the nail in the medullary canal and to reduce rotations of fractures.
They can be inserted in oblong holes either for static or dynamic locking.
