An anterior cervical plate system is provided. The cervical plate includes a retention ring with a deflectable flange that is upwardly spaced from the top surface of the ring and configured to prevent an inserted bone fastener from backing out of the plate. The plate includes a locking pin having a camming surface and a blocking surface. When the camming surface is moved into position adjacent to the flange, the flange is free to flex out of the way of a bone screw being inserted into or removed from the plate. When the blocking surface is positioned adjacent to the flange, outward deflection of the flange is prevented to retain the bone screw inside the plate. The locking pin is rotated through a camming surface to bring a blocking surface against the flange deflecting the flange onto the head of the bone screw.

An intramedullary bone fixation device that includes a shaft with a flexible region. The flexible region may be configured to flex from a first shape to a second shape as the shaft moves along a curved medullary canal. For example, the bone fixation device may include a distal bone screw that is configured to move along the curved medullary canal of first and second segments of a fractured bone (e.g., two segments of a broken rib) and fasten to the segment bone segment. The bone fixation device may include a locking member (e.g., a proximal bone screw) that is configured to lock the shaft to the first bone segment. For example, the shaft may be fixed to the distal bone screw and ratchetably coupled to the shaft such that the first and second bone segments can be compressed together by urging together the distal bone screw and the locking member.

A compression nut for treating a bone includes a head and a body extending longitudinally from the head to a free end. The body includes a first portion including an exterior surface tapering from the head toward a second portion. An exterior threading extends along an exterior surface of both the first portion and the second portion of the body. The nut also includes a channel extending longitudinally through the body. The channel includes an interior threaded extending along an interior surface of the channel configured to threadedly engage a portion of a locking screw therein.

A device, kit and method for the correction of spinal deformity using an anterior approach. The device comprises a screw-head platform (102), wherein the screw-head platform (102) comprises a primary recess (112) for receiving a primary rod (114), and a main vertebral body screw (104) rotatably connected to the screw-head platform (102).

A fracture treatment system can include a pair of implants cross-pinned into the medullary canal of a bone, guided by at least one guide wire with at least two diameters. The system allows for more accurate sizing of the length of implants needed to achieve bicortical purchase for enhanced stability, as well as anti-rotation of the fracture site. The more accurate sizing and placement of the cross-pinned implants additionally allow both ends of the implants to recess beneath or be flush with the outer surface of the bone, which can reduce the risk of infection. The guide wire can allow the implants to be inserted using a cannulated technique for easier surgical procedure and better outcome, with the implants having sufficient wall thickness for the desired length to achieve bicortical purchase while keeping the shaft outer diameter of the implant to be similar to a diameter of the guide wire.

An improved method of fusing the sacroiliac joint and tools for accomplishing the same is disclosed. In one embodiment, the present invention is a method that uses an intra-articular joint fusion device for connecting the sacrum and ilium that includes creating a first incision in the patient's skin proximal to the patient's sacroiliac joint, inserting a surgical channel tool into the incision from the patient's posterior, creating a void in the sacroiliac joint, inserting a fusion implant into the void, the fusion implant having at least one fixation element for engagement with bone tissue in the articular surfaces of the sacrum and the ilium, and driving the fusion implant into the void such that the at least one fixation element engages with bone tissue in an articular surface of at least one of the sacrum and ilium, and the fusion implant fixes relative positions of the sacrum and ilium.

A two-piece suspension pedicle anchor and its system and component-set is disclosed. The two-piece suspension pedicle anchor comprises a proximal piece and a distal piece that can rotate relatively. An external thread is arranged on the outer surface of the proximal piece, and a transverse through hole for an artificial ligament to pass through is arranged at the distal piece. As the two-piece suspension pedicle anchor is rotated and gradually locked into the bone, only the proximal piece is rotated, and the distal piece with the artificial ligament is pushed down but not rotated; in addition, the artificial ligament will be brought into the bone along with the distal piece and sandwiched between the outer surface of the proximal piece and the bone, that is, the artificial ligament will be sandwiched and fixed between the anchor-bone interface without wrapping around the outer surface of the proximal piece.

The self-contouring plate system for bone fractures allows a surgeon to bridge a bone fracture, primarily in bones of complex shape where the use of plates or screws is difficult. The self-contouring plate is formed from a series of similar or identical rigid elements, the elements able to bend and rotate with respect to each other. This flexibility is initially helpful as the surgeon contours the device to the shape of the bone. When the desired shape is reached, the elements are locked into place. The length of device is adjusted by adding or removing elements, much like a necklace. Each element of the self-contouring plate includes a ball that extends away from a body, a cavity for receiving the ball of the neighboring plate, and a screw to compress the ball within the cavity.

A system, and method of using the system, for changing the angle of a bone of a subject is provided by the present disclosure. In one embodiment the system includes a non-invasively adjustable implant configured to be placed inside a longitudinal cavity within the bone and comprising an outer housing and an inner shaft telescopically disposed in the outer housing, at least one of the outer housing and inner shaft associated with a first anchor hole and a second anchor hole, the first anchor hole configured to pass a first anchor for coupling the adjustable implant to a first portion of bone and the second anchor hole configured for to pass a second anchor for coupling the adjustable implant to the first portion of bone, the inner shaft configured to couple to a second portion of bone that is separated or separable from the first portion of bone, such that non-invasive elongation of the adjustable implant causes the inner shaft to extend from the outer housing and to move the first portion of bone and the second portion of bone apart angularly; a driving element configured to be remotely operable to telescopically displace the inner shaft in relation to the outer housing; and wherein the first anchor hole is configured to allow the first anchor to pivot in at least a first angular direction and the second anchor hole is configured to allow the second anchor to translate in at least a first translation direction.

A variety of K-wires with imbedded plates are disclosed that allow for the plate in K-wire to be secured to the bone after insertion. Further, a donut shaped washer for capturing and securing the K-wire is disclosed. Also, a screw with a channel is disclosed that has a head shaped to capture and secure the K-wire. Finally, embodiments of a slotted washer are disclosed that captures and secures the K-wire.
