An orthopedic button assembly providing the ability to perform a soft tissue repair or bone repair using a method for securing sutures or fixation members in a knotless manner is described. The orthopedic button assembly of the present disclosure is designed in a manner to as to not rely on an additional component to perform the locking. The orthopedic button assembly of the present disclosure includes the ability to optimally tension the repair by pulling the tensionable fixation members (e.g. sutures) in the tensioning direction and prevent slippage of the tensionable fixation members in the opposite direction by capturing the tensionable fixation members in a manner such that pulling on the tensionable fixation members in the direction opposite of the tensioning direction (e.g., if connected tissue or bone were to attempt to 'pull away' from the button assembly under tension) actually increases the tension, resulting in a tighter locking interface to increase the security of the repair.

Knotless orthopedic stabilization system and related methods

Button-suture assemblies which employ a knotted locking mechanism do not maintain tension when securing bone and tissue fragments. A knotless method and device for maintaining tension and providing precise placement of a button-suture assembly during stabilization procedures comprising a locking pin, which mates with a button creating pinch points with increased surface area through which suture can pass from a baseplate through two dedicated openings in the button, one for the first end of the suture and one for the second end of the suture while preventing tension loss during the locking step and therefore allowing for precise placement of the button-suture assembly.

Knotless orthopedic stabilization system

A system and method comprising an anchor assembly including an anchor and a locking element, a tensionable fixation member (e.g., surgical suture, tape, etc.), and a release member, wherein the anchor further comprises a first end, second end and anchor body. The anchor is configured for implantation into bone. One end of a tensionable fixation member is configured for attachment to a tissue to assist with fixation of the soft tissue. Once the anchor has been seated in bone, the second end of the tensionable fixation member is pulled through a 'one-way only' passage in the body of the anchor. When the tensionable fixation member enters passage, it traverses past the locking element positioned within the anchor by bending or deflecting the locking element out of the way to permit passage of the tensionable fixation member while maintaining contact with the tensionable fixation member via elastic compression that results from the elastic bending or deflection of the locking element but prevents the tensionable fixation member from passing back. This continuous locking on the tensionable fixation member creates fixation security, allows for optimal tensioning, and prevents loosening in the opposite direction. The release member may be used to bend or deflect the locking element to loosen the tensionable fixation member to enable an operator to readjust the tension in the tensionable fixation member to the operator's liking.

Re-tensionable suture anchor system and related methods

A modular poly-axial bone screw includes a poly-axial bone screw, a poly-axial tulip head, and a collet disposed within the tulip head, the collet interacting with the bone screw and tulip head providing an interference fit with the bone screw head to lock orientation of the tulip head on and relative to the bone screw. Inner configurations of the tulip head interact with outer configurations of the collet to lock axial and/or rotational position of the collet within and relative to the tulip head, and thus about the bone screw head. The collet also has a base configured to conform to a top of a bone screw, wherein the collet is configured to support the bone screw and the tulip head when a spine rod is fixed in the tulip head.

Bottom loading polyaxial screw

An interspinous process device includes a first plate, a second plate, and a transverse member between the first plate and the second plate, wherein the second plate is adjustably coupled to the transverse member. A post is coupled to the transverse member and a spring mechanism is disposed between the post and the first plate. The spring mechanism is configured to provide a preloaded compression force to the first and second plates. Methods of implanting the interspinous process device using an inserter tool are also disclosed.

Apparatus and method of treating spinous processes

A spine implant for use in spinal facet joint fixation or to connect distracted portions of a vertebral lamina in a laminoplasty through use or non-use of a spacer. One or two bone screw plates are angularly adjustable relative to a base plate for attachment by bone screws to vertebral bone. One form of the spine implant has a base plate, a first plate pivotally connected to the base plate for angular adjustment relative to the base plate and configured to hold one or two bone screws for attaching the first plate to first vertebral bone, and a second plate configured to hold two bone screws for attaching the second plate to second vertebral bone. The second plate may be pivotally connected to the body for angular adjustment of the second plate relative to the base plate or fixed to the base plate at a predetermined angle.

Spinal facet joint and laminoplasty implant

A modular polyaxial bone screw includes a poly-axial bone screw, a polyaxial tulip head, and a collet disposed within the tulip head, the collet interacting with the bone screw and tulip head providing an interference fit with the bone screw head to lock orientation of the tulip head on and relative to the bone screw. Inner configurations of the tulip head interact with outer configurations of the collet to lock axial and/or rotational position of the collet within and relative to the tulip head, and thus about the bone screw head. The collet also has a resilient, tapered base with a plurality of slots in and about its end that allow the end to splay outwardly over and upon the head of the bone screw to create a snap or frictional interference fit between the splayed collet and the bone screw head when a spine rod is fixed in the tulip head.

Modular bone screw

A modular pedicle screw assembly has a multi-part cam lock structure for fixing a threaded shank to a head subassembly. A modular pedicle screw assembly provides capture and release of a spherical end of a threaded shank by a head through rotation of closures radially disposed in an internal chamber of the head. Geometry of the closures cooperate with geometry of the internal chamber, providing a selective cam action between the closures and the internal chamber to increase and decrease size of an opening formed by the closures. Closure rotation produces an open state where the spherical end of the threaded shank can pass through the closures, releasing the spherical end of the threaded shank from the head, and a closed state where the spherical end of the threaded shank cannot pass through the closures thereby capturing the spherical end of the threaded shank in the head.
