Patent ID: 10307245

Abstract:
A device is provided for retaining a tendon, such as, but not limited to, a flexor digitorum tendon onto an associated bone such as, but not limited to, the plantar aspect of a proximal phalangeal base for correction of a toe contracture. The tendon retention device is defined by a tack and a sleeve. The tack is configured for press-fit or instrument aided reception into the tendon and associated bone to retain the tendon against the associated bone. The sleeve has an internally threaded bore for threaded reception onto a threaded shaft of the tack from the opposing side of the associated bone. The sleeve further has a head with an anti-loosening feature or anti-loosening features such as, but not limited to, tangs and/or cutouts, that engage the associated bone to aid in preventing the sleeve from working loose from the bone and/or unthreading from the tack.
