A spinal rod connector includes first and second arm assemblies and a fastener. The first arm assembly includes a first base portion and a first head portion defining a first slot configured to receive a first spinal rod. The first base portion includes a hook and an extension member including a housing. The second arm assembly is adjustable with respect to the first arm assembly. The second arm assembly includes a second base portion including a hook, a second head portion defining a second slot configured to receive a second spinal rod, and an elongate member extending from the second base portion. The elongate member is configured to be received in the housing of the first arm assembly. The elongate member is rotatable about an axis offset from a longitudinal axis of the housing. The fastener is configured to be received in the housing to secure the elongate member.

A medical device includes a spinal rod receiving channel disposed within the medical device and a rod retaining set screw, wherein the spinal rod receiving channel includes an upper arc having a first end and second end, a first middle arc connected to the first end of the upper arc, a second middle arc connected to the second end of the upper arc and disposed opposite the first middle arc, connecting slants connected to first and second middle arcs, and a lower arc connected to the connecting slants, and the rod retaining set screw configured to secure a spinal rod disposed in the spinal rod receiving channel into the medical device.

The present teachings provide one or more surgical implements for repairing damaged tissue, such as in the case of a spinal fixation procedure. A bone anchor is provided. The anchor can include a bone fastener. The bone fastener can include a head and a second end adapted to engage an anatomy. The bone fastener can extend along a longitudinal axis. The anchor can also include a coupling arrangement coupled to the head of the bone fastener so that the bone fastener is rotatable about the longitudinal axis to define a first plane of motion. The anchor can further include a saddle, which can be coupled to the coupling arrangement. The saddle can be movable relative to at least one of the bone fastener and the coupling arrangement to define a second plane of motion.

Surgical instruments, methods, and systems are provided for securing spinal fixation elements to bone. For example, a spinal fixation system is provided that has a receiver with proximal and distal ends. The proximal end of the receiver is configured to receive various fixation members, such as spinal rods and set screws, therein. The distal end of the receiver has a hook member that is operably coupled thereto and has an opening that is configured to receive bone therein. The hook member is configured to be secured to bone without penetrating the bone.

A spinal hook includes a hook member, an inner collet, and an outer portion. The hook member includes a head portion and a blade portion. The inner collet includes a base portion configured to rotatably engage the head portion and a pair of engaging portions defining a slot configured to receive a connecting rod therein. The outer portion is movable relative to the inner collet between a locked position in which the outer portion causes the pair of engaging portions to move toward each other and an unlocked position in which the outer portion causes the pair of engaging portions to be spread apart to facilitate insertion or removal of the connecting rod.

A spinal fixation device is provided. The spinal fixation device includes a body portion including a stud portion defining a first annular groove. An outer housing is positionable on the stud portion of the body portion. An inner housing defines a second annular groove and is positionable between the outer housing and the stud portion. A ring member is positionable within each of the first and second annular grooves of the respective stud portion and inner housing to lock the inner housing to the body portion and to fixedly couple the outer housing to the stud portion.

Arcuate fixation members with varying configurations and/or features are provided, along with additional components for use therewith in provided fixation systems and intervertebral implant systems. The arcuate fixation members may be of varying lengths, cross sectional geometries, and/or cross sectional areas, and may be configured with various features such as heads configured to accept other fixation system components, tabs to allow arcuate fixation member-in-arcuate fixation member or fixation anchor-in-arcuate fixation member configurations. Applications of fixation systems and intervertebral implants systems utilizing arcuate fixation members are particularly suitable when a linear line-of-approach for delivering fixation members is undesirable.

Methods of inserting and retaining interbody fusion material are disclosed. In some embodiments, the methods include inserting an anchored implant comprising a bone anchoring portion and an engagement portion. A method may also include inserting at least one bone fusion material within a disc space between two adjacent vertebral bodies. In some embodiments, a method includes driving the bone anchoring portion into an outer surface of at least one of the adjacent vertebral bodies and recessing the bone anchoring portion within the outer surface of the at least one adjacent vertebral body.

A screw-clamp apparatus is disclosed that may include a first clamp component comprising a first attachment end and at least one hook on a first hook end, a second clamp component comprising a second attachment end and at least one hook on a second hook end, a bone-screw hole located in one of the first clamp component and the second clamp component, a bone screw configured to be inserted through the bone-screw hole and to be inserted into bone, a first spacer-receiver located on one of the first clamp component and the second clamp component, and a length adjusting mechanism configured to adjust a longitudinal length of the screw-clamp apparatus. The first attachment end and the second attachment end are configured to attach the first clamp component and the second clamp component together. The first spacer-receiver is configured to secure a spacer.

Orthopedic fixation devices and methods of installing the same. The orthopedic fixation device may include a coupling element and a bone fastener, whereby the bone fastener can be loaded into the coupling element through the bottom of a bore in the coupling element and a retention member is configured to allow polyaxial rotation of the bone fastener and also to lock the bone fastener in place upon application of a force on a saddle and clamp in the coupling element.
