Embodiments may include an attachable fastener, which may include a bondable material that may be secured to the end of an end effector. Vibration may be tuned to occur at a distal end of the fastener. Accordingly, the fastener may be used to generate heat at a distal point of contact. If the contact surface contains bondable material, that material may be softened. If the fastener includes bondable material at the point of contact, that material may also be softened by heat produced by vibration at the contact area. A hard implant or another polymeric material may function as the anvil.

An implant assembly may include a screw with a head having a head feature and an implant. The implant may be securable to a bone of a patient with the screw. The implant may include a bone plate, a rotatable structure having a top surface and a bottom surface. The bottom surface may include a lock feature. The lock feature may engage the head feature when the rotatable structure is in a locked orientation and disengage the head feature when the rotatable structure is in an unlocked orientation. The rotatable structure may couple to the bone plate such that the rotatable structure is rotatable between the locked orientation and the unlocked orientation. The head feature may be one of a ridge and a radial groove and the lock feature may be the other one of the ridge and the radial groove.

A facet joint replacement system includes a facet joint replacement device including an enclosing body and an articulating body. The enclosing body includes an interior surface defining an inner cavity of the enclosing body. The interior surface includes a first articulating surface and a projection extending inwardly relative to a surrounding area of the interior surface. The articulating body is positioned within the inner cavity of the enclosing body and is configured to move within the enclosing body. The articulating body includes a second articulating surface and a recess extending inwardly relative to a surrounding area of the articulating body and aligned with the projection of the interior surface of the enclosing body so as to allow movement of the projection along the recess of the enclosing body while constraining rotational motion of the articulating body within the enclosing body.

A cervical spine plate attachment system includes a cervical spine plate that has a first surface configured to rest upon a first vertebra and a second vertebra, a second surface opposite the first surface and facing away from the first vertebra and the second vertebra, and a plurality of holes configured to receive fasteners to secure the cervical spine plate to the first vertebra and the second vertebra. The system also includes an alignment guide that detachably mounts to the cervical spine plate. The alignment guide comprises a pair of bars that rest upon the second surface of the cervical spine plate when the alignment guide is mounted to the cervical spine plate. The system also includes a fastener configured to secure the alignment guide to the cervical spine plate.

A personalized fixation system includes a surgical planning software tool configured to adjust relationships of relevant anatomy of a subject, at least one bone anchor, a plate having a shape that does not conform to a single plane, the plate configured to accept the at least one bone anchor, wherein the shape of the plate is at least partially determined by the surgical planning software tool, and wherein the plate includes at least one node having a hole configured to receive the at least one bone anchor, and a locking element configured to connect the at least one bone anchor to the plate, wherein the plate is manufactured using additive manufacturing.

An anchoring system for implanting in bone, the system comprising a first coupling assembly having a first clamp and a first coupling body that receives and holds a first stabilization element; a second coupling assembly that receives and holds a second stabilization element; and a plate that attaches to the first coupling assembly and the second coupling assembly, wherein the first coupling assembly attaches to a bone fastener, and wherein the first coupling body includes a cap retainer that receives a locking cap that applies a directional force to force the first coupling body toward the plate, and applies another directional force to force the first clamp toward the plate, thereby fixedly securing the first coupling body and the first clamp to the plate.

The invention provides the internal fixation system of multi-function adjustable spine posterior screw-rod. It not only includes the vertebral plate, but also includes the adjustable connecting rod, screw and lock nut. Among them, vertebral plate is curved, its internal cambered surface directly faces the spine, and external cambered surface of vertebral plate is equipped with a reinforcing rib. The vertebral plate is set with the perforative injecting hole, and the external cambered surface of vertebral plate is set with the located block. The surface of the located block is set with the concave threaded hole, and the located block on two sides of the threaded hole is set with the U-shaped bracket. The top of screw expands to form a locking block, which surface is set with the concave locking hole. The locking block on both sides of locking hole is set with the U-shaped locking groove.

The present invention provides a method for stabilizing a fractured bone. The method includes positioning an elongate rod in the medullary canal of the fractured bone and forming a passageway through the cortex of the bone. The passageway extends from the exterior surface of the bone to the medullary canal of the bone. The method also includes creating a bonding region on the elongate rod. The bonding region generally aligned with the passageway of the cortex. Furthermore, the method includes positioning a fastener in the passageway of the cortex and on the bonding region of the elongate rod and thermally bonding the fastener to the bonding region of the elongate rod while the fastener is positioned in the passageway of the cortex.

Implants, systems, and methods for securing multiple cords to bone. The fixation system may be used for correcting scoliosis with a fusionless double corded device. The system may include first and second cords, a single bone fastener, one or more tulip structures configured for receiving one or both of the first and second cords, and one or more locking caps adapted to lock one or both of the first and second cords.
