  • Patent number: 9949762
    Abstract: A posterior vertebral stabilizer has a resilient member such as a linear spring, which operates in tension and compression. The resilient member may be kept straight by a stabilization rod extending through the spring, or by a telescoping assembly that encases the resilient member. The ends of the stabilizer are attachable to pedicles of adjacent vertebrae so that the stabilizer adds stiffness to control flexion and extension of the vertebrae. Two such stabilizers may be used, and may be connected together by a crosslink designed to limit relative rotation of the stabilizers. Thus, the stabilizers may restrict axial rotation and lateral bending between the vertebrae, while permitting stiffened flexion and extension. Such stabilizers help provide the stiffness of a healthy intervertebral disc. In the event that fusion of the joint becomes necessary, a set screw or other component may be used to further restrict flexion and extension.

  • Patent number: 8968374
    Abstract: A biocompatible interference screw for soft tissue or bone-to-bone fixation comprises a screw body extending from a screw head to a distal tip of the screw. The screw body has an outer surface, and comprises polyether-ether-ketone (PEEK) material. Advantageously, the body outer surface has a textured surface finish for substantially improving pull-out strength of the interference screw. The textured surface finish is textured, in preferred embodiments, with a minimum of approximately 16 micro inches of surface roughness. The screw head comprises a tapered square keyhole for receiving a distal end of a driver instrument. The screw comprises a series of threads, which have a relatively smooth profile, in order to prevent graft tissue laceration as the screw is being inserted. The distal tip of the screw body comprises a narrow tip, and a distal end of the screw body is angled inwardly toward the narrow distal tip.

  • Patent number: 8864804
    Abstract: Devices and methods are disclosed for the fusion of joints (particularly finger joints or toe joints) in a bent (or angled) position. In certain embodiments, the device is pre-bent and inserted into the joint in its pre-bent configuration. Alternatively, the device may be configured to have a first position wherein it is bent and a second position wherein it is straight. In that case, the device is preferably straightened by inserting a K-wire through a cannula in the device, and the device can be inserted into the joint in its straight position. Once inserted, the device is permitted to move to its bent position, which moves the joint to a bent position. In one embodiment the device moves to its bent position when the K-wire is removed.

  • Publication number: 20140277192
    Abstract: The disclosure provides examples of an open architecture anchor for securing soft tissue to bone, for example, to repair a torn rotor cuff. The anchor includes a helical screw thread having a base and two sidewalls that are non-linear. The non-linear sidewalls extend from opposing ends of the base and meet at a peak. The non-linear sidewalls are circumscribed within a triangle defined by the peak and ends of the base. Compared to the standard triangle profile, the helical screw thread profile has a smaller cross-sectional surface area and, consequently, removes less bone. The helical screw thread having the reduced cross-sectional area preserves bone stock and enhances the holding strength of the anchor in bone.
