The present invention relates to a surgical screw connection system (100) for use in the region of the pelvic bone. The surgical screw connection system (100) comprises or consists of at least one rod (10) with a first end section (11) and a second end section (13). The rod (10) is cannulated throughout and the first end section (11) consists of or comprises a first threaded section (111). The present invention also relates to an instrument set (200), a treatment set and a method for securing a locking nut (21)

An anchor for anchoring tensile members to bone includes: a housing extending along a central axis, with a hollow interior; a collet in the hollow interior having a central bore for accepting tensile members and an exterior surface, the collet being configured to swage around and against tensile members; a sleeve having a peripheral wall defining interior and exterior surfaces, the sleeve disposed in the housing's hollow interior axially adjacent to the collet, and movable parallel to the central axis between first and second positions; and wherein at least one of the collet exterior surface and the sleeve interior surface is tapered and the sleeve and the collet are arranged so movement of the sleeve from the first position to the second position causes the sleeve interior surface to bear against the collet exterior surface, causing the collet to swage radially inwards around and against one or more tensile members.

A bolster system having a first bolster device, a second bolster device, and an adjustable tether that includes a one-way pre-tied slideable adjustment knot. The adjustment knot is at a first position prior to insertion of the first bolster device into a passageway in one or more bones. The second bolster device includes a body portion having an outer portion that is sized to be received in the passageway and/or in an aperture of a bone plate. The body portion also includes a channel that is sized to accommodate recessed and/or embedded placement of the pre-tied slideable adjustment knot. The second bolster device can also include an oversized plate portion that abuts against a cortex of a bone or a wall of a bone plate. The second bolster device can also include a threaded member or retention tab that lockingly secures the second bolster device to a bone plate.

The present invention relates, in some embodiments thereof, to orthopedic implantable devices for treatment of periprosthetic bone fractures, the devices include an elongated cylindrical shaft extending between a distal end and a proximal end, wherein a proximal portion extends from the proximal end, the proximal portion sized and shaped to allow for an engagement with a distal tip of a preexisting bone implant, the proximal portion comprising at least one longitudinal slot extending from the proximal end and providing a relatively flexible proximal portion configured to mate with various sizes and shapes of preexisting bone implants.

A bone anchor includes a flexible strand defining a first adjustable loop and a friction knot coupled to a proximal end of the first adjustable loop. The friction knot is configured to allow adjustment of the first adjustable loop in a first configuration and is configured to prevent adjustment of the first adjustable loop in a second configuration. A knot capsule includes a body defining an internal knot cavity. The friction knot and a portion of the first adjustable loop are positioned within the internal knot cavity. The internal knot cavity defines one or more impingement surfaces configured to maintain the friction knot in a fixed position within the internal knot cavity when the friction knot is in the second configuration.

Bone and joint stabilization devices or systems are described that include multiple-layer bodies. The approach offers dramatically improved fatigue life as compared to one-piece spring members that are otherwise similar or comparable. Coordinated improved-strength anchor embodiments, anchor loading tools and methods of use are also described.

The guidance and positioning device may be a system for creating a passage in tissue, positioning fasteners or other implants, and tensioning an elongated fastening member, like a suture, thread, wire, or pin. In some embodiments, the device may allow for the implantation of multiple sutures and fasteners in tissue. A fastener may be positioned at the distal end of a flexible pushrod. The fastener may be connected with the pushrod or may be loosely fitted with the distal end of the pushrod. A suture may be looped through or connected with the fastener such that one, two, or more sections, legs, strands, or portions of the suture extend from the fastener.

Methods of joint repair employing sutures and attached fixation devices are discussed. For example, a bone block graft procedure (e.g., Latarjet) is discussed which employs fixation devices to secure contact between graft surfaces of two bones. A suture construct, including a continuous suture loop routed through a first fastener, is secured to a first bone. Looped ends of the suture loop are passed through passageways formed in the two bones. The looped suture ends are further routed through a second fastener. The second fastener is mounted to the second bone and a sliding knot, formed in the looped suture ends, is advanced into contact with the second fastener. The suture is further tensioned using a tensioner device to secure the two bones together.

Methods of use for bone and joint stabilization devices are described in which the devices are tensioned after anchoring during a medical procedure and remain active in maintaining axial tension for continued compression of the subject anatomy.

A crimp cap apparatus includes: a crimp sleeve having a peripheral wall defining an exterior surface and an interior passage sized to receive a tensile member having a predetermined outer diameter, the crimp sleeve being configured such that it can be crimped around the tensile member by an application of mechanical force which reduces its dimensions from a first size to a second, smaller size; and a cap having a bottom surface, a convex top surface, a central bore extending from the bottom surface to the top surface for receiving the crimp sleeve, wherein the cap includes a clamping structure disposed in the central bore and configured to permit elastic deflection in response to being pressed over the crimp sleeve the crimp sleeve and apply a clamping force there-to to secure the cap in place.
