  • Publication number: 20210267649
    Abstract: A metatarsal fixation device is provided for fixation of osteotomy or fracture of a distal metatarsal metaphysis bone of the human foot and for fixation of an associated capsule to the metatarsal head. The device includes a metallic bone plate with a series of screw holes along an elongated portion of the plate and a combination of a singular screw hole and a resilient clamp on an end of the elongated portion. The resilient clamp has two arched resilient arms extending laterally outward from an end of the elongated portion. Each arm has a plurality of spikes on an inner surface thereof providing points of contact that compress and attach a metatarsal phalangeal joint capsule portion to the medial and/or lateral aspect of the metatarsal head, thereby facilitating realignment of the metatarsophalangeal joint and respective digit. The resilient arms are biased to grasp lateral sides of a metatarsal head and any associated capsule portion.

  • Patent number: 11045305
    Abstract: Soft tissue retention devices, instrumentation and related methods are disclosed. The devices include a first member comprising a first head portion and a first threaded shaft portion extending from the first head portion that define a cannulated opening extending therethrough, and a second member comprising a second head portion and a second threaded shaft portion extending from the second head portion that define a cannulated opening that extends therethrough. The inner sides of the first and second head portions includes a row of teeth extending about the periphery thereof. The first head portion also includes a plurality of through holes positioned between the first threaded shaft portion and the row of teeth. The outer sides of the first and second head portions include non-circular drive openings. The instrumentation comprise a handle portion with a through aperture that allows for a user's finger to extend therethrough during an implantation procedure.

  • Patent number: 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.
