A modular system for treating a bone includes a main body including a channel extending therethrough. A distal end includes a driving feature sized and shaped to engage a corresponding driving structure of one of first and second bone screws. The system also includes an inner shaft sized and shaped to be inserted into the channel and including a distal end including a retaining feature for engaging a corresponding retaining structure extending within a recess at a proximal end of the first screw. Furthermore, the system includes an outer shaft extending longitudinally and including a channel extending therethrough. The channel of the outer shaft is sized and shaped to slidably receive the main body therein and including a retaining feature extending along a distal end thereof. The retaining feature of the outer shaft engages a retaining structure extending along an exterior surface of the second screw.

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.

A bone screw insertion device, comprises an outer sleeve extending from a proximal end to a distal end and including a channel extending therethrough and a driving member extending longitudinally through the channel of the outer sleeve from a proximal end to a distal end configured to engage a driving recess of a bone screw, the outer sleeve movable relative to the driving member between a first position in which the distal end of the outer sleeve extends over and covers a proximal portion of a bone screw engaged with the driving member, to a second position in which the distal end of the outer sleeve is longitudinally aligned with a proximal end of a bone screw engaged with the driving member.

Various power screwdrivers with screw delivery systems are disclosed. In some embodiments, an apparatus attachable to a power screwdriver comprises a housing, a cartridge barrel having a plurality of barrel chambers, each capable of holding a screw and drive-bit assembly, and a drive shaft assembly. The drive shaft is aligned with a barrel chamber. The drive shaft has a handle sleeved thereon. The handle is coupled to a barrel cam connected to the cartridge barrel. Moving the handle proximally to a retracted position and then distally to a neutral position rotates the cartridge barrel in a way that the drive shaft is aligned with a barrel chamber adjacent the previous barrel chamber. Moving the handle distally to a forward position advances a screw out of a port.

An anchor device for use in sacroiliac joint stabilization comprises a housing having one or more apertures; one or more engagement members at least partially disposed in the housing, where at least one of the one or more engagement members is movable between a retracted position and an extended position such that, when in the extended position, the at least one of the one or more engagement members extends through at least one of the one or more apertures; wherein, when in the extended position, the at least one of the one or more engagement members is configured to move to the extended position within cancellous bone of a sacrum; and wherein the anchor device comprises a continuous channel extending from a first end of the anchor device to a second end of the anchor device, the channel being configured to receive a guidewire.

A bone fixation assembly is disclosed. The bone fixation assembly may include a bone fixation plate including a fastener hole and a cavity adjacent to the fastener hole. The bone fixation assembly may also include a clip. The clip may include a body having a partial circular shape, the body positioned at least partially in the cavity. The clip may further include a plurality of tabs extending inward relative to the partial circular shape of the body, each tab having a convex shape extending inward relative to the partial circular shape of the body, wherein the body and the plurality of tabs are positioned below a top surface of the bone fixation plate.

A sacroiliac joint implant system includes a primary implant configured to be received in a sacroiliac joint of a patient and a secondary implant configured to couple with the primary implant. The primary implant includes a body extending from a proximal end to a distal end and a plurality of threads extending from the body. The secondary implant includes a first anchor configured to anchor within a sacrum of the patient and a second anchor configured to anchor within an ilium of the patient.

A bone anchor system may include a bone anchor assembly and a driver tool. The bone anchor assembly may generally include a bone screw, a collar member, and a tulip member. The collar member may include first and second retaining arms configured to receive a retaining feature of the driver tool. The driver tool may be removably couplable to the bone anchor assembly by inserting the retention feature between the first and second retaining arms of the collar member, such that the retention feature is retained by the first and second retaining arms of the collar member.

Bone fixation systems include various combinations of stabilizing members, dynamic elements, fasteners, and locking mechanisms. Bone plates receive dynamic bone staples and bone screws. Other dynamic elements include elbow pegs, straight pegs, and wire pegs.
