Methods of correcting a spinal deformity, including securing a first rod on a first side of a spine, securing an anchor on a second side of a spine, securing a lateral coupling between the rod and the anchor, translating and/or derotating the spine and securing a second rod on a second side of the spine to provide secondary stabilization to the spine.

Various implants and surgical techniques for dynamic spinal tethering systems are discussed. In an example, a spinal tethering system can comprise a flexible elongate spinal tethering cord and a plurality of vertebral implants connecting the cord across at least four spinal levels. In this example, each vertebral implant of the plurality of vertebral implants can include a dynamic head coupling each vertebral implant to the cord. The dynamic head of each vertebral implant can be configured to share cord tension across multiple spinal levels by releasing a first tension generated at a first level between two vertebral implants of the plurality of vertebral implants to generate a second tension across two spinal levels between three vertebral implants of the plurality of vertebral implants, wherein the second tension is lower than the first tension.

Systems and methods for reducing the risk of PJK, PJF, and other conditions are disclosed herein. In some embodiments, a longitudinal extension can be added to a primary fixation construct to extend the construct to one or more additional vertebral levels. The extension can be attached to a first attachment point, such as a bone anchor implanted in a vertebra that is superior to the primary construct. The extension can also be attached to a second attachment point, such as a component of the primary construct or an anatomical structure disposed inferior to the first attachment point. The extension can be more flexible than the primary construct and/or can limit motion to a lesser degree than the primary construct, thereby providing a more-gradual transition from the instrumented vertebrae to the natural patient anatomy adjacent thereto. The extension can be placed with little or no soft tissue disruption.

A system to stabilize and guide the growth of the spinal column includes an elongated support member having a width and a length and a guiding connector having a bone connecting portion and a guiding portion. The bone connecting portion secures the guiding connector to a vertebrae and the guiding portion has a bearing element with a passageway adapted to receive the elongated support member. The bearing element permits relative sliding movement of the elongated support element in the passageway of the bearing element. The system may further include a bone fixation element has an elongated support member receiving channel, a locking mechanism and a bone anchoring portion. The bone anchoring portion secures the bone fixation element to bone. The locking mechanism secures the elongated support member in the channel. The guiding connector is moveable along the elongated support member to permit and control the growth of the spinal column along a predetermined path.

A low-profile offset-type spinal fusion device includes a first screw, a connection base, a nut and a compression part. The first screw has an external thread and a flange. The connection base includes a penetration part and a connection part disposed no higher than the penetration part, and can sleeve the first screw through a first hole of the penetration part to contact the flange with opposite ends of the first screw protruding out of the first hole. The nut, used to engage the first screw, has a bottom surface to contact against the penetration part. When the first screw is installed by penetrating the first hole, the nut and the flange are located to opposite ends of the first hole. The compression part is to screw into a cavity of the connection part for depressing a connecting bar tightly in the cavity.

Systems and methods include solutions for fixation at the rib head for fractures and osteotomies adjacent to the rib head and transverse process. The disclosed rib plates, anchor systems, other implants, and instrumentation may also be applied to mid-rib fractures. The systems and methods may be used in the treatment of rib deformities, including the correction of rib hump deformity via thoracoplasty, as well as general corrections of chest and rib deformities. Systems and methods herein may be used in chest wall reconstructions due to trauma, cancer, or deformity.

A bone plate for treating periprosthetic fractures includes a head portion to be positioned along a greater trochanter of a bone. The head portion includes pairs of bone fixation element receiving openings extending therethrough from a first surface of the plate which, when the plate is in an operative position, faces away from the bone, and a second surface which, when the plate is in the operative position, faces toward the bone. A pair of cable holes extend through the head portion from a first longitudinal side connecting the first and second surfaces to a second longitudinal side connecting the first and second surfaces. The head portion includes a pair of hooks for engaging a superior ridge of the greater trochanter. The plate also includes a shaft portion extending distally from the head portion to extend along a portion of the bone distal of the greater trochanter.

A system for correcting a spinal deformity includes an implant fixed to one side of a vertebra and a rod extending along an axis of the spine on a second side of the vertebra. An adjustment member, which may include a reel, is coupled to the rod. A force directing member, such as a cable, extends between the rod and the adjustment member. The force directing member is retractable toward and extendible from the adjustment member. A method of correcting spinal deformity includes providing an implant, a rod, an adjustment member coupled to the rod, and a force directing member extending between the rod and the adjustment member. The adjustment member can be retractable toward and extendible from the adjustment member.
