tifix^® is a plate system with a free choice of screw position. 

Locking screw technology signifies a frictional connection. This 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.

	IMMEDIATE INSERTION OF THE SCREW
	NO THREAD FORMING
	Easy SELECTION OF SCREW ANGLE
	SIMPLE METAL REMOVAL
	The screw head threads itself in the lip within the plate hole and deforms it. The locking between the screw and the plate is produced by cold welding process between the two materials.

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. 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.
