tifix^® is an locking screw plate system with a free choice of multidirectional screw position. Locking screw technology signifies a frictional connection. It is found as a construction principle in nature and is based on areal transmission of load and forces (frictional connection). This effective principle also allows implants to be of smaller dimensions than before and nevertheless achieve a greater loading capacity. The flow of forces and thus the loading of the individual screws vary. The flow of forces is greatest through the screw next to the fracture line and is about half, it is about one-third through the next screw and the remaining screws bear the rest.

	INSTANT MOUNTING OF SREWS
	NO THREAD FORMING
	VARIABLE ANGLE
	EASY TO UNLOCK
	The easy principle consist of a material-lip in the plate-hole. By mounting the screw head into the thread, the material-lip transformes to a part of the thread and solidifies by cold welding.

Locking screw technology leads to optimal areal transmission of forces in the area of contact between the bone and screw and plate. This avoids overloading of bone or implant. The multidirectional screw positioning makes work easier for the surgeon and the effect is reinforced by the optimal biomechanical position and by the greater screw lengths. The result is that the longest possible tifix® screw is the most effective. The tifix^® screw head is threaded and this thread locks in the plate hole through reshaping proceses due to differences in material hardness and design. The connection demonstrates high strength. The screw position varies from 0°-15°. Greater angles can be obtained with the aid of a thread former. For biomechanical reasons, the plate holes should be filled with at least 2-3 locking screws on either side. The remaining plate holes can also be filled by conventional screws (e.g. to bring a fragment closer and fix it). Metal removal is easily carried out.
