New Jersey Patent of the Month – June 2024

Extremity Medical, LLC, a medical device company, has been granted a patent for their new approach to bone fusion that promises to transform orthopedic procedures. This innovative approach features a meticulously designed assembly comprising three primary members: the first and second elongated bodies, each with threaded shafts, and a straight third member with specific apertures and bores. These components work together to achieve optimal bone fusion, ensuring stability and precision.

The process begins with the insertion of the third member into a bone fragment. This member, characterized by its cylindrical shape and strategically placed apertures, serves as the anchor for the first and second members. The first member, which features a tapered head and self-tapping edge, is inserted through the first aperture of the third member, passing through the bore and exiting at the second aperture. This configuration allows the first member to partially reside within the bone fragment, providing a secure initial fixation.

Next, the second member is introduced in a similar manner, through the third aperture of the third member, exiting at the fourth aperture. This dual insertion method ensures that both members are tightly coupled with the third member, creating a robust fusion system. The unique design of the threads on each member allows for differential threading, enhancing the mechanical grip and stability of the fusion.

One of the key advantages of this system is the ability to deliver uniform compression across the bone fragments, a critical factor in successful bone healing. The threaded members are designed to exert precise pressure, promoting effective bone fusion while minimizing the risk of complications such as screw head breakout or inadequate bending resistance.

This method not only simplifies the surgical process but also significantly improves the outcomes of bone fusion surgeries, particularly in challenging areas like the foot and hand. Extremity Medical’s innovative approach addresses the limitations of traditional bone fusion techniques, offering a reliable and efficient solution for orthopedic practitioners.
