A helicoil interference fixation system comprising:

a helicoil comprising a helical body comprising a plurality of turns separated by spaces therebetween, the helical body terminating in a proximal end and a distal end, and at least one internal strut extending between at least two turns of the helical body; and

an inserter for turning the helicoil, the inserter comprising at least one groove for receiving the at least one strut;

the helicoil being mounted on the inserter such tin at the at least one strut of the helicoil is mounted in the: at least one groove of the inserter, such that rotation of the inserter causes rotation of the helicoil.

Multi-function driver instruments and related methods are disclosed herein, e.g., for applying a fastener to a bone anchor. In some embodiments, a single instrument can include features for driving multiple different types of fasteners, independently driving multiple different components of a single fastener assembly, and so forth, with the instrument being switchable between multiple operating modes to select the feature needed for a particular function. The instrument can include features for retaining a fastener to the instrument, e.g., during initial insertion of the fastener.

Driver instruments and related methods are disclosed herein, e.g., for applying a fastener to a bone anchor. Various features are disclosed for retaining the fastener to the driver instrument, such as tapered drive tips, as are various features for impacting the driver instrument into the fastener, such as slidable slap-hammer type handles. Driver instruments with interchangeable handles or handle geometries that can be changed without separating the instrument from an attached fastener are also disclosed.

The present disclosure relates to a suture anchor. The suture anchor includes a body having a proximal end and a distal end, the body including threads along at least a partial length of the body and at least one through hole, the threads including a profile such that the threads located near the distal end of the body include a first shape and the threads located near the proximal end of the body include a second shape different from the first shape. Delivery devices and anchor dilators are also disclosed.

A fixation system for spinal instrumentation comprising a cap (1), which houses the head of a screw (2), the end of said screw (2) projecting through a lower opening of said cap (1). A coupling element (3) having two tabs (33) on both side ends rests on the upper part of the head of said screw (2). Said coupling element (3) houses therein an adjusting ring (4) secured to a series of tabs (7), by which means the movement of the head of said screw (2) can be limited.

Disclosed is a universal pedicle screw removal tool comprising a tapered shaft having an L shaped tip on one end and a generally square head on an opposite end. A lower section leads to a tapered section which is connected to a handle. The handle may include a set of serrations to provide increased grip. The handle is connected to the head. The tip is sized to engage the channel of a tuliped pedicle screw while the head is sized to engage a ratchet or other torque producing tool. In an alternate embodiment, the tip is T shaped. In another alternate embodiment, the handle section includes opposing members extending from the shaft to form a T shaped handle. In use, the tip is inserted into the channel of a tuliped pedicle screw while the shaft is rotated to unscrew the pedicle screw from a patient's bone.

Implants and instruments for providing an ideal trajectory for the insertion of instruments and screws during implantation of an interbody implant in a spinal surgery are disclosed.

The present disclosure relates to an anchor. The anchor includes a suture bridge having a proximal end and distal end. The distal end of the suture bridge has a thickness greater than a thickness of the proximal end of the suture bridge. At least two ribs extend from the proximal end of the suture bridge to a proximal end of the anchor. At least one open helical coil wraps around the at least two ribs and extends, substantially, from the proximal end of the suture bridge to the proximal end of the anchor. The at least one open helical coil defines an internal volume communicating with a region exterior to the anchor through apertures between turns of the at least one open helical coil. The at least two ribs are engagable with a grooved shaft of a driver.

A driver instrument for engaging and transferring rotational torque to a bone anchor already screwed into a bony structure. The driver instrument may be advanced through an incision while disengaged from the bone anchor and thereafter engaged in a driver socket of the bone anchor. The driver instrument includes an elongate shaft extending distally from a handle, a tapered distal tip, and a driver engagement feature located proximally of the tapered distal tip. The tapered distal tip and the driver engagement feature are configured such that the longitudinal rotational axis of the driver instrument automatically moves into parallel alignment with the longitudinal rotational axis of the bone anchor as the driver engagement feature of the driver instrument is advanced into the driver socket of the bone anchor.

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.
