A spinal distraction system, according to one aspect, includes an adjustable spinal distraction rod comprising first and second members, the adjustable spinal distraction rod configured for non-invasive elongation of the first and second members. The system includes an anchor rod configured for mounting to a bone of a subject, the anchor rod having one or more spring-biased tabs disposed at one end thereof, and a connector having first end and a second end, the first end having a receiving cup configured for detachable mounting on the anchor rod, wherein the one or more spring-biased tabs are configured to engage with an inner surface of the receiving cup, the connector having a second end operatively coupled to an end of a first member and wherein the second member is configured for mounting to a second bone of a subject.

The present invention is generally directed to orthopedic fixation devices that comprise a pre-assembled double headed tulip assembly, having two tulip elements to receive rods, wherein the assembly may be configured to receive a bone fastener in at least one of the tulip elements. At least one of the tulip elements may comprise a saddle and a ring to attach the double headed tulip to a bone fastener.

A spinal stabilization system includes a plurality of anchors and at least one bridge. Each anchor includes a clamp configured to engage an anatomical element, the clamp movable between a fully open position and a fully closed position; a locking screw configured to selectively prevent the clamp from being moved into the fully open position; and a bridge interface. The at least one bridge is a rigid member having a first end and a second end opposite the first end, each of the first end and the second end having an anchor interface. The bridge interface is configured to receive the anchor interface.

The present disclosure relates to embodiments of a patient-specific or patient-matched, customized apparatus for assisting in various surgical procedures. In varying embodiments, patient-specific guides may comprise multiple patient-specific surfaces for mating with the underlying patient anatomy and may further comprise one or more protrusions or projections for facilitating placement and attachment, at least temporarily, to the desired location of the patient's anatomy. The apparatus described herein are preferably used with cervical and/or certain thoracic levels of the human spine and may comprise single or multi-level guides for placement of instruments and/or implants during a variety of surgical procedures.

A device and method for use which stabilizes a target motion segment of the spine without the use of screws or any form of hardware implanted into the vertebrae. By being comprised of modular segments and assembled onto the target motion segment at the time of implantation, it can be provided in kit form designed for each patient. The stabilization apparatus general comprises elements; one is adjustably secured to the posterolateral aspect of the caudal vertebra of the target motion segment, with another element being secured to the base of the spinous process of the cranial vertebra of the target motion segment. These two elements are then coupled to each other by either an elongated rod-like connecting element, or extensions from the two anchoring elements which then couple.

A bone anchor is provided for connecting a rod to a bone structure, the bone anchor having a rod housing configured to accommodate the rod; a cavity distal to the rod housing dimensioned to accommodate the bone structure; and a deployable purchase element capable of assuming a deployed position in which the purchase element protrudes into the cavity, and capable of assuming a non-deployed position in which the purchase element does not substantially protrude into the cavity.

Dynamic reference arrays use markers and trackers to register a patient's anatomy to computer system. Wherein the dynamic reference array may be screwed into a patient's spinous process, clamped on to a spinous process, or attached to the spinous process using posts. In embodiments, a dynamic reference array may comprise a single structure comprising and attachment member and a scaffold. In alternate embodiments, the dynamic reference array may comprise distinct structures that allow the dynamic reference array to swivel and collapse in order to facilitate registration, while not interfering with a surgical procedure.

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.

The present invention is an implant for bone. The current implant is particularly useful in spinal surgical procedures.
