In biomechanical study, aap Implantate’s LOQTEQ® anatomical fracture plating system displayed better explantation properties than those of the market leader. While not directly stated, it is presumed that the study compared LOQTEQ to DePuy Synthes’ technology.
Over-tightening during implantation and the effects of cyclic loading can cause a screw to seize during removal of locking plate implants, after a fracture has healed. This study assessed removal torques before and after cyclic dynamic loading that simulated the patient’s daily activity. Screws were inserted at manufacturer-recommended torque, as well as at increased levels.
During explantation with the market leader’s mechanism, over-tightening resulted in an increase of ~40% in the removal torque compared to tightening the screw with the manufacturer’s recommended torque. Tests of LOQTEQ’s mechanism showed that over-tightening had no effect on seizing of the locking screws. Further, with cyclic loading, the removal torque of the locking screws consistently increased by ~40% to 70% for the market leader’s screws, while LOQTEQ registered an increase of 20%.
LOQTEQ implants feature a screw-hole geometry that allows simultaneous fracture compression and angular stable fixation in one step, using one screw. This obviates the need to change the drill or use other auxiliary instruments to set the plate, saving time in the O.R. As noted in our report of aap’s 3Q18 revenue, the LOQTEQ plating system will soon gain various polyaxial products that are in the CE Mark approval process, while foot and periprosthetic systems have been submitted for FDA clearance.
