In 2010, after undergoing surgery to repair a sports hernia that required intensive repairs to not only the abdominal area, but also to several tendons in the right leg, Seward retired from the NFL and took a job with the NFL's Representative Office in Mexico City.
Artelon's intended use includes resurfacing of joint surfaces (e.g. osteoarthritis, Hallux rigidus) and reinforcement and augmentation of tissue repair ( e.g. ligaments, tendons, general soft tissues).
Opposite the metacarpophalangeal joint each tendon is bound by fasciculi to the collateral ligaments and serves as the dorsal ligament of this joint; after having crossed the joint, it spreads out into a broad aponeurosis, which covers the dorsal surface of the first phalanx and is reinforced, in this situation, by the tendons of the Interossei and Lumbricalis.
