Controlled, axial flexibility

Zimmer® MotionLoc® Screws

In animal studies, Far Cortical Locking Technology provides controlled axial flexibility to promote fracture healing through callus formation, or secondary healing, by stressing the fracture with micromotion at the fracture site.1

Reduces Stiffness

  • MotionLoc Screws uses far cortical locking technology as a strategy to reduce the stiffness of a locked plating construct. The stiffness reduction through the screws create nearly parallel micromotion at the fracture site. 

User-friendly

  • Creates nearly parallel micromotion at fracture site. In addition, facilitates screw removal with reverse cutting threads.    

Accuracy

  • The system utilizes provisional fixation with k-wires or drill bits for accurate plate placement.

Locking Threads

This is the portion of the screw that locks into the plate. The head of the screw is threaded to match the threaded holes in the plates. 

Motion Control Collar 

The diameter of this portion has been reduced in comparison to the distal end of the screw. This allows the screw within the drilled hole to flex through elastic deformation without permanently deforming the screw. This is called the working length of the screw because this is the area that flexes a controlled amount to create the desired micromotion at the fracture site.

Reverse Cutting Threads

The reverse cutting threads on the working length of the screw are designed to ease screw removal. The reverse cutting threads are designed to engage with the near cortex before the threads on the tip of the screw disengage with the far cortex, so the screw can be backed out.

Cortical Threads

The cortical threads are the portion of the screw that fixes into the cortical bone for hold. It has the same thread form as a standard cortical screw and is inserted using a standard surgical procedure. Since MotionLoc screws are only fixed in the far cortex, radiographs must be inspected to confirm the screw tip has completely engaged that cortex.
