Instruments, implants, bone plates, systems and methods for correcting bone deformities and fractures in the lower extremity are disclosed. Specifically, targeting instruments, implants, bone plates, systems and methods used for correcting bone deformities and/or fractures in the foot using compression are disclosed.

Bone anchor assemblies and related methods are disclosed herein that can provide for improved fixation of a primary bone anchor. A bone anchor assembly can include a wing with a distal portion that can define a plurality of auxiliary bone anchor openings. Each auxiliary bone anchor opening can receive an auxiliary bone anchor that can augment fixation of a primary bone anchor of the bone anchor assembly. The plurality of auxiliary bone anchor openings can be oriented such that, when the wing is coupled to a primary bone anchor assembly of a vertebral level in a first configuration, at least one auxiliary bone anchor can be driven to extend across a facet plane of the vertebral level and, when coupled in a second configuration, each auxiliary bone anchor received within the wing can be driven to conform to the vertebral level.

A bone plate a re-orientable tab that provides a buttress support to fragments of the surrounding concave joint rim. The tabs can be re-orientated to contact the rim to provide close support. Each tab includes a hole sized to closely receive a K-wire to permit the K-wire to apply a bending load to a tab in situ to bend the tab about a lower recess between the tab and the remainder of the head. A soft tissue anchor is sized to pass through the hole in the tab, and into a hole drilled into the underlying bone. The soft tissue anchor has a bone engaging first portion and second portion comprising a length of flexible suture, to which is affixed a needle. The needle and suture can be used to draw tissue about the joint capsule.

An orthopedic stabilization device is provided having a first button and a suture. The first button includes a base portion and a locking loop extending from a distal surface thereof, and a locking member slidably receiving the locking loop. At least a portion of the suture extends through the locking loop superior the locking member in the axial direction and at least a portion of the suture extends through the locking loop inferior the locking member in the axial direction such that a portion of said suture is frictionally retainable between said locking member and said locking loop when the suture is tensioned. The device may include a second button with the suture disposed between the first and second buttons such that the suture may be held in tension therebetween.

A bone plate assembly may include a bone plate with an obverse side, a reverse side, a fastener hole formed through the bone plate from the obverse side to the reverse side, a first draw hole formed through the bone plate from the obverse side to the reverse side, with a wire engagement surface, a fastener insertable through the fastener hole and into tissue, and a first wire insertable into the first draw hole, with a distal end anchorable in the tissue and a proximal end with a retention portion that is retainable in the first draw hole. The wire engagement surface may be oriented obliquely relative to a pilot hole formed in the tissue to receive the wire such that motion of the first wire through the first draw hole exerts a compressive force against the tissue.

The invention comprises a medical implant system with implant having a fastener hole for a fastener and further including a fusion screw, positioned to avoid interference with the implant fastener. The medical implant system also includes a guide that is mounted in the fastener hole and from an edge of the implant which provides for defined adjustability for angulation, and optionally depth, to allow for placement of the fusion screw so as to avoid impingement with the implant and the fasteners that secure it in place. The invention also relates to a method of surgery using the system.

A bone plate system comprises a bone screw and a bone plate having at least two screw-receiving hole structures, at least one of the hole structures comprising an eccentric portion adjacent a first seating area for biasing bone in an inferior fusion area into dynamic compression as the screw is advanced, and a cowl portion that at least partially defines a second seating area and being positioned to enable cross-screw compression of an inferior fusion area. The screw is seatable in either the first or second seating area at the option of a surgeon. A surgical method generally comprises inserting a bone screw into the compression plate and compressing bone in an inferior fusion area by either dynamic or cross-screw compression.

A bone plate according to an exemplary aspect of the present disclosure includes, inter alia, a body portion. The body portion includes a first slotted portion extending at least partially through the body portion and a plurality of teeth adjacent the first slotted portion for engaging a driver in the first slotted portion. The body portion also includes a second slotted portion extending at least partially through the body portion and a ramped portion at least partially surrounding the second slotted portion. The ramped portion tapers from an outer surface of the body portion toward an inner surface of the body portion.

An apparatus for a bone fusion assembly is provided for compressing adjacent bones across a bone fusion site to encourage fusion thereof. The bone fusion assembly includes a generally elongate member comprising a plate that has one or more fixation apertures to receive fasteners that are configured to be coupled with the adjacent bones. A threaded fastener comprising a bone screw, including a head portion and a shank, is configured to traverse the bone fusion site. A slanted aperture disposed in the plate is configured to receive the bone screw at a predetermined angle with respect to a plane of the plate. The slanted aperture comprises a smooth countersunk surface and one or more teeth that are configured to cooperate with the head portion of the bone screw to compress the adjacent bones together and encourage bone fusion therebetween.

A bone plate has a shaft portion having first and second side surfaces spaced from a centerline of the shaft. A plurality of holes extend from an upwardly facing surface of the shaft to a bone contacting surface. A first hole having a center located closer to the first side of the shaft than the centerline, and a second hole located closer to the second side of the shaft than the centerline. The upwardly facing surface of the shaft having a first tapered area extending from adjacent the first circular hole downwardly towards the second side of the shaft and the upwardly facing surface of the shaft having a second chamfered area extending downwardly from adjacent the second circular hole to the first side of the shaft. The tapered areas having wider and narrower portions with the center of each circular hole located adjacent the wider portion of the tapered area.
