This disclosure relates to surgical fixation systems and methods. The surgical fixation systems of this disclosure may include various combinations of fixation devices, soft suture constructs, and/or adjustable loops and are configured for use in various knotless surgical methods, including but not limited to, syndesmosis, AC joint, UCL, bunion, anterior cruciate ligament (ACL), and posterior cruciate ligament (PCL) surgical methods.

An intramedullary nail implant for positioning in a bone having a head and a shaft defining an intramedullary canal. The implant includes a distal portion having a shaft extending along a central axis and configured for positioning within the intramedullary canal. A proximal portion extends proximally from the distal portion. The proximal portion defines a contact surface which extends at least in part medially of the central axis such that it is configured to extend within a medial portion of the bone head. A method of implanting the nail is also provided.

The invention primarily relates to fastening and stabilizing tissues, implants, and/or bondable materials, such as the fastening of a tissue and/or implant to a bondable material, the fastening of an implant to tissue, and/or the fastening of an implant to another implant. This may involve using an energy source to bond and/or mechanically to stabilize a tissue, an implant, a bondable material, and/or other biocompatible material. The invention may also relate to the use of an energy source to remove and/or install an implant and/or bondable material or to facilitate solidification and/or polymerization of bondable material.

Suture passer systems for tissue suspension and tissue compression, and more particularly for tongue suspension, are described. The system can include at least a first elongate tubular body or shaft, a needle having a lateral bias carried by the elongate body, and a retrieval element operably connected to the elongate tubular body. The needle can have a substantially straight configuration when located within the elongate tubular body, and be configured to exit an opening at or near a distal end of the elongate tubular body and assume a laterally biased or curved shape to form a path through tissue. The needle is configured to carry a suture. The retrieval element can be configured to retrieve the suture carried by the needle after the needle has formed a curved or otherwise angled path through tissue. The system can also include one or more bone anchors to secure the suture loops. Methods of placing one or more suture loops into tissue, such as the base of the tongue, are also described.

The variable or adjustable depth medical implants disclosed herein are cable of depth adjustment prior to implantation. The variable depth implants permit a single implant to provide multiple footprint configurations, allowing a surgeon adjustability in the operating room. The implants can comprise a metallic lattice designed for specific physical properties, such as an elastic modulus. In some examples, the main body of the implant is taller than the adjustable portion of the implant so that the physical properties of the main body of the implant are controlling at the implant site. In some embodiments, the variable implant is constructed in an additive process as a single unit.

Disclosed herein is, in some embodiments, a multi-segment bone anchor configured to allow variable bone ingrowth or attachment between each segment. In some versions, a lower segment is configured to allow bone ingrowth and a detachable upper segment is configured to prevent bone ingrowth, making the bulk of the bone anchor removable.

The present disclosure provides a system, method, and cannulated anchor for treating acute or chronic instability of two boney structures in a patient. The provided cannulated anchor includes an opening through which suture, and in some instances a tendon graft, may be positioned. The cannulated anchor also includes a securing mechanism that helps maintain its position when installed in bone, such as flexible prongs, angled tabs, or ridges. The cannulated anchor is installed by being translated over a k-wire with a cannulated inserter that engages the cannulated anchor. The k-wire passes through the tendon graft, if used, as the cannulated anchor is translated over the k-wire. Passing the k-wire through the tendon graft allows the tendon graft to take up more space within the cannulated anchor's opening versus being biased to one side of the k-wire during insertion.

A suture anchor includes an anchor body having a longitudinal axis, a proximal end, and a distal end. The anchor body includes a central bore located at the proximal end and a passage extending between the central bore and the distal end. The central bore has a first dimension substantially perpendicular to the longitudinal axis, and the passage has a second dimension substantially perpendicular to the longitudinal axis less than the first dimension. The suture anchor includes a flexible strand extending through the passage, and a first knot formed in the flexible strand at the distal end has a third dimension greater than the second dimension to prevent the first knot from passing through the passage. A closed loop is positionable at least partially within the central bore and formed entirely by the flexible strand without forming any additional knots on the flexible strand extending proximally from the first knot.

A joint replacement system for repairing an articular surface of a first bone of a joint includes an anchor portion and an implant portion. The anchor portion includes an anchor to be secured to the bone, and an anchor fixation head including a bone-facing surface (BFS) extending radially outward from the anchor and an implant facing surface (IFS) extending from a periphery of the BFS. The implant portion is formed from a material (e.g., CoCr) more dense than the material of the anchor portion (e.g., Ti) and includes a fixation cavity to receive at least a portion of the anchor fixation head (AFH), the fixation cavity includes an anchor facing surface (AFS) configured to form a frictional connection with the IFS, and a load bearing surface having a contour for articulating against a cooperating articulating surface of a second bone of the joint.

Surgical impact driver adaptors may be connected between a powered surgical instrument and a driven surgical device when performing surgical procedures, such as those involving the implantation of a surgical implant into bone, for example. During surgical procedures, the surgical impact driver adaptors may limit a transfer of a rotational force from the powered surgical instrument to the surgical device until a sufficient axial force is applied to the impact driver adaptor from the powered surgical instrument.

A method for securing a strand to a fixation member for arthroscopic fixation, wherein the fixation member includes a channel on an exterior surface and an aperture therethrough. The method includes passing a strand having first and second ends through a flexible sleeve, passing the sleeve through the aperture of the fixation member in a first direction, tensioning the strand, and pulling the sleeve in a second direction different than the first direction to secure the sleeve to the fixation member without tying the strand on the fixation member.
