PERMOfix is a modular linking system. Rods can be connected to joints in free chosen angles, just by fastening a screw. As easy as it locks, it releases. The rods can be freely inserted in or from the joints. Adjustments can be done at any time. The system offers a rigid fixation in all directions. Combining the basic parts all kinds of modules can be made. These modules create the possibility to connect a device in a simple, efficient, and flexible way. ​
