Medline Launching REFLEX Nitinol Dynamic Disc for Foot/Ankle

The Medline UNITE Foot & Ankle Division is releasing technology that transforms a  traditional lag screw into a dynamic construct that provides continuous compression and gap recovery.

The REFLEX Nitinol Dynamic Disc System harnesses nitinol's superelastic and shape memory properties to dynamize an otherwise traditional lag screw. An in vitro study performed by the company demonstrated continuous compression and gap recovery up to 4.0 mm.

The REFLEX Nitinol Dynamic Disc System is cleared for use with UNITE® Titanium Cannulated Screws. After guidewire placement, measurement and drilling, a specially designed countersink creates a pocket in the bone's cortex to accommodate the disc.

The disc is placed over the screw's shaft and, upon final seating and tightening, the screw's head deforms the dynamic disc. The disc is mechanically engineered to resist deformation, and the effect leads to continuous compression between two bone fragments.

Scott Goldstein, Director of Marketing, said, "Orthopedic implants created from shape memory alloys like nitinol offer clinically recognized strength, efficiency, ease of use, and continuous compression. The addition of the REFLEX Nitinol Dynamic Disc System enhances the compression of the overall construct to drive better patient outcomes."
