Abstract: The present invention is a method and device for the correction and reduction of bone deformities, such as metatarsus primus adductus, using a plate body with winged buttresses and dorsal loop. The method and device can be affixed to a bone without any drilling or violating of the bone and can use a tethering technique which does not require drilling into the second metatarsal, nor does it require the placement of a prominent suture knot/button device medially along the first metatarsal.

Abstract: A retainer member formed of bone secures tissue relative to a bone. The retainer member forms an opening in a compact outer layer of the bone. The retainer member is enclosed in a tubular member or sleeve to prevent breaking of the retainer member during formation of the opening in the bone. The extent of movement of the retainer member into the hone in the patient's body is determined as the retainer member is moved into the bone. A suture may be connected with the retainer member and used to connect tissue with the bone. The retainer member may be positioned across a fracture in a bone to hold portions of the hone relative to each other. The retainer member may be used at a joint between end portions of bones to immobilize the joint and be released by breaking the retainer member.

Abstract: The disclosure includes a bone plate extender and extension system. The system includes a first bone plate extender and may additionally include a bone fixation element and/or an additional bone plate. The bone plate extender may be affixed to a bone portion at one end, for instance, a fractured bone portion, via a bone fixation element, and associated with a second bone plate at an opposite end, so as to facilitate alignment and stabilization of the bone and thereby correct and treat a bone fracture. The bone plate extender may include an extended body, which includes a bone plate engagement portion, a bone fixation portion, and an intercalating portion there between. In certain variations, the extended body is planar, and in certain variations the extended body is angled, curved or arced. Methods of using such bone plate extension systems for the reduction, restoration and treatment of bone fractures are also provided.

The fusion portion is distal to the first portion and configured to conform to a scaphoid and a lunate. The first portion includes scaphoid hole and a lunate hole.

Abstract: A cervical plate is disclosed. The plate includes plate body with a first end adapted for attachment to a first vertebra in a cephalad relation to the plate body and a second end adapted for attachment to second vertebra in a caudad relation to the plate body. The plate body being of a first thickness at the first end and of a second thickness at the second end, the first thickness being smaller than the second thickness, and the plate body transitioning from the first thickness to the second thickness in a graduated manner.

Abstract: A fixable suture anchor plate including an anchor plate having a tunnel aperture that aligns with one or more bone tunnels formed in the bone. The anchor plate also includes one or more suture passages that align with one or more grooves formed along an edge of the anchor plate to permit passing a suture through the anchor plate after the anchor plate is fixed to the bone. The anchor plate also includes a screw hole that allows the anchor plate to be fixed to a bone with a screw. A method for tendon-to-bone repair includes sewing a medial row of stitches proximate to a medial line of tendon-to-bone attachment and securing the suture to the anchor plate through a bone tunnel and sewing a lateral row of stitches along a lateral line of tendon-to-bone attachment and securing the second suture to the anchor plate.

Abstract: A system for the internal fixation of a fractured bone of an elbow joint of a patient includes at least one bone plate, each bone plate having a plurality of holes and generally configured to fit an anatomical surface of the fractured bone. The at least one plate is adapted to be customized to the shape of a patient's bone. The system also includes a plurality of fasteners including at least one locking fastener for attaching the bone plate to the bone. At least one of the holes is a threaded hole. Guides for plate benders, drills, and/or K-wires can be pre-assembled to the threaded holes, and the locking fastener can lock into any of the threaded holes after the guides are removed.

Abstract: A method for effecting reduction, stabilization and enhancement of fusion of the human cranio-cervical junction, which may be performed in order to relieve mechanical stresses imparted to the spinal cord and brainstem as a result of an abnormal clivo-axial angle, includes steps of achieving the correct craniocervical relationship, of effecting a fusion of a first portion of a bone forming material based structural member to a human cranium, and effecting fusion of a second portion of the bone forming material based structural member to a least one portion of a human cervical spine. Fusion of the bone forming material based structural member to the human cranium may be promoted through the use of plate member that is shaped to define a graft accommodation space between the plate member and the cranium.
