摘要： A spinal rod/rod system for spinal stabilization is controllably bendable or flexible along its longitudinal axis to achieve a particular radius of curvature, flex, arch or angle of the spinal rod and preserve the achieved angle through a locking mechanism. The spinal rod is controllably bendable through application of a controlled axial force. Such controllable curvature allows for limited movement of the vertebrae connected by the present resilient spinal rod system. The present spinal rod is defined by a multi-component system which includes an inner spring rod and an outer rod tube. An angulation ring is threadedly attached to an end of the spring rod and provides controlled adjustment of the angle or curvature of the spinal rod through axial compression of the spring rod relative to the outer tube. Locking prevents the increase and/or decrease of angulation of the spinal rod. A titanium spacer ring may be provided that is situated between the spring rod and the outer rod tube in order to prevent and/or hinder over angulation. One or more spacer rings may be situated between the spring rod and the outer rod tube axially adjacent each side of the titanium spacer ring that act as an additional spring force in bending, and act as a shock absorber in the axial compression of the of the spinal rod. The rings may be made of various durometers.

摘要： A spinal cross connector is configured for connection between spinal rods and provides allowance or space for spinal extensor muscles once the spinal process has been removed. The cross connector has curved first and second connection members that are adjustable in length and rotation relative to one another. A first clamping member is provided on the first connection member and defines first and second arcuate jaws that are adapted to clamp onto a first spinal rod. A second clamping member is provided on the second connection member and defines first and second arcuate jaws that are adapted to clamp onto a second spinal rod. Both the first and second clamping members are rotatable and thus provide the rotational adjustment. The cross-connector also provides easy in situ sizing and adjustability.

摘要： Instruments are provided for delivering and installing a multi-section spinal implant in-situ one section at a time by sequential deployment and assembling of the multi-section spinal implant sections into an intervertebral space. An advancement mechanism provides controlled deployment of individual implant sections from the instrument. Each instrument accepts a plurality of implant sections that are stacked on a deployment rod. Activation of the advancement mechanism advances a pusher against a rearward implant section of the implant section stack. This, in turn, advances all or some of the implant sections such that the forward most implant section exits the instrument. As the advancement mechanism is further activated, additional implant sections are deployed from the instrument. In this manner, a multi-section spinal implant of any number of implant sections may be delivered and assembled in situ. In one form, the advancement mechanism comprises an indexing mechanism. In another form, the advancement mechanism comprises a ratchet device provided on and between a trigger and an advancement tube.

摘要： A dynamic spine plate is formed with only a single row of bone screw bores that extend along a generally superior/inferior axis of the spine plate, providing a single-sided dynamic spine plate. The single-sided dynamic spine plate is formed from a plurality of spine plate components that are coupled dynamically to one another. This provides a modular, single-sided dynamic spine plate. The spine plate components are coupled dynamically to one another via socket and projection interfaces, the socket and projections interfaces incorporating resilient coupling and retention structures that allow limited movement of the spine plate components relative to one another. This provides for dynamic extension of the spine plate components relative to one another. The resilient coupling structure connects the spine plate components, providing a self-biased, snap fit coupling of spine plate components. Rotation stabilizers may be provide on the present single-sided dynamic spine plate that provide rotational stability to the spine plate in addition to the bone screws that will attach the spine plate to the vertebrae.

摘要： A spinal implant in the form of a spinal facet fastener is configured to hold, restrict and/or limit flexion and/or extension of a spinal facet joint and/or immobilize movement thereof. The spinal facet fastener is formed with leg segments configured for reception in, on and/or about vertebral bone of a spinal facet joint and a connecting segment that holds the leg segments apart a spaced distance. The spinal facet fastener has surfaces that are configured to abut vertebral bone surfaces of a spinal facet joint to hold, restrict and/or limit flexion and/or extension of the spinal facet joint and/or immobilize movement thereof. In one form, the spinal facet fastener has members that are configured for reception in vertebral bone of the vertebral bone portions that form the spinal facet joint. In this form, the spinal facet fastener may include an anchoring element that is configured for reception between the vertebral bone portions that form the spinal facet joint. In one form, a first leg is configured to abut a surface of an inferior articular process of a first vertebra while a second leg is configured to abut a surface of a superior articular process of a second vertebra that is adjacent the first vertebra. The spinal facet fastener is formed of a biocompatible material such as PEEK (polyetheretherketone) but may be formed of other biocompatible materials such as a biocompatible metal (e.g. titanium or stainless steel).

摘要： A spinal rod guide and/or guide assembly is provided for mounting a spinal rod onto a spinal rod holder/connector of a vertebral bone screw. The spinal rod guide is configured to extend between an opening in a patient's body and the spinal rod holder of the vertebral bone screw assembly, to receive a spinal rod therein, and thereafter accurately guide the spinal rod into the spinal rod holder. The spinal rod guide is defined by a first elongated arc portion and a second elongated arc portion to define a guide tube for the introduction and placement of additional spinal rod components onto the spinal rod connector, particularly, but not necessarily, for securing the spinal rod into the spinal rod connector. The elongated arc portions are mountable or initially attached onto a top of a spinal rod holder of a spinal rod bone screw assembly. The elongated arc portions (tube) define first and second longitudinal slots extending from a top of the elongated arc portions to a bottom of the elongated arc portions. The two longitudinal slots are situated such as to be diametrically opposite one another. Each longitudinal slot aligns with a spinal rod slot of the spinal rod holder to thereby allow easy placement of the spinal rod into the spinal rod holder. Thereafter, the defined elongated tube provides direct communication and alignment with the top of the spinal rod holder in order to receive a spinal rod connector drive screw for securing the spinal rod into the spinal rod holder.

摘要： A spinal rod connector provides single step locking of a spinal rod relative to a bone screw. The single step lock-up is in line with the vertebral bone screw while still allowing for effectively 360° of rotation of a portion of the spinal rod connector assembly with the spinal rod (but functionally 180° or +/−90° of the 0° position depicted in the various figures). The present spinal rod connector assembly utilizes components having V-shapes of various angles to provide holding of the spinal rod. A pulling and compression force locks the spinal rod onto the spinal rod connector and thus relative to the vertebral bone screw to which the spinal rod connector assembly is attached. The present spinal rod connector allows easy sliding down on guides of the spinal rod connector assembly since spinal rod rotation locks up from the rod being pulled towards the vertebral bone screw.
