A surgical fixation system can include a fixation device, a loop connected to the fixation device, a graft carried by the loop, and a reinforcement material. Surgical fixation systems can be used in various tissue reconstruction procedures, including but not limited to, ACL and PCL reconstructions. The graft and the reinforcement material may be tensioned independently of one another to avoid stress shielding the graft.

A bone fixation system comprises a first fastener configured to anchor into a first vertebrae, a second fastener configured to anchor into a second vertebrae, and a set screw to retain the second fastener to the first fastener. The first fastener includes a shaft extending along a longitudinal axis and a head. The shaft includes a first cylindrical body. The head of the first fastener includes a second cylindrical body defining a passageway having an interior surface. The passageway defines a longitudinal axis that is different than the longitudinal axis of the shaft. The first cylindrical body of the shaft and the second cylindrical body of the head are angled relative to each other. A head of the second fastener is configured to engage the interior surface of the passageway of the head of the first fastener. The set screw retains the head of the second fastener in the passageway.

The present invention is a fastener (30). The current fastener (30) is particularly useful in surgical procedures. Among other things, the surgical fastener (30) is provided with a conduit (50, 210) to dispense or carry biocompatible substances.

A surgical instrument system and method of use is disclosed. The system includes a bone fixation pin and a surgical instrument configured for use with the bone fixation pin. The surgical instrument includes a sheath extending over the distal end of an elongated shaft and a locking mechanism operable to permit selectively movement of the elongated shaft along the longitudinal axis relative to the sheath.

A wedge has an outer perimeter and includes a top surface extending generally in a first plane and having a top osteointegration surface disposed thereon. A bottom surface extends in a second plane that extends obliquely with respect to the first plane. The first plane intersects the second plane outside the outer perimeter of the implant and includes a bottom osteointegration surface disposed thereon. A plurality of side surfaces extends between the top surface and the bottom surface and defines the outer perimeter, wherein at least a portion of the plurality of side surfaces is devoid of any osteointegration surface.

A bone screw is provided that reduces insertion torque when driving the screw into bone while maintaining pull-out strength. The provided bone screw includes one or more threads having a portion with a reduced flank profile that helps reduce the amount of torque required to drive the bone screw into bone. The portion with the reduced flank profile has an equal thread depth or height as the portion of the one or more threads with a non-reduced flank profile, thereby helping to maintain pull-out strength. The reduced flank profile portion is away from the bone screw's insertion tip. As such, the bone screw's non-reduced flank profile portion creates internal female threads that have a correspondingly larger flank profile than the screw's reduced flank profile portion, thereby reducing friction between the reduced flank profile portion of the one or more threads and the interior female thread.

A femoral fixation device may include a shaft and a helical thread disposed about the shaft between a first location and a second location along the shaft. The helical thread may include a concave undercut surface. The femoral fixation device may be configured such that, when the femoral fixation device is implanted within a neck and a head of a femoral bone: the first location, the second location, and the helical thread therebetween may be disposed within the head of the femoral bone; the concave undercut surface may be oriented toward a proximal end of the femoral fixation device; and the concave undercut surface may be configured to transmit at least one force from the head of the femoral bone to the neck of the femoral bone.

A system for manipulating a rotational device using a flexible guide rod with an external rod feature along its length to engage a rotational device with a complementary interior channel feature along its length. A driver having a handle and coupling element is coupled to the rotational device while the flexible guide rod extends from the handle, through the coupling element, and into the interior channel of the rotational device in order to rotate from within along the length of the device.

Compression anchor systems, devices, instruments, implants, and methods for using the compression anchor systems, devices, instruments, and implants are disclosed. The compression anchor system including an implant and a suture anchor. The compression anchor system may also include an inserter for engaging the implant and receiving at least a portion of the suture anchor. The implant may include a threaded head and a shaft with at least one thread portion and at least one anchor portion. Finally, methods for assembling and surgically inserting the anchor system are also disclosed.
