A system is utilized, which comprises a cross connector for use in spinal fixation, further comprising multiple connection features configured to accommodate for direct attachment to multiple rods. Teachings are directed to a device that not only provides increased construct stiffness in flexion, extension and lateral bending, but also in torsion. The system adds stiffness in standard constructs. Joining multiple adjacent constructs with varying rod sizes for load distribution are also benefits of the system.

The present invention is a spinal fixation device that includes an occipital rod having a first end and a second end, and a spinal rod extending from a connection housing having a first end and a second end. The first end of the spinal rod is integral with a portion of the connection housing and the connection housing is configured with an elongated opening, a rotating plug, and a locking mechanism. The elongated opening is configured for mating with the first end of the occipital plate and the locking mechanism is adapted to enable the occipital rod to be locked in a fixed position.

A polyaxial bone device includes a screw, a screw housing, and a spring. The screw includes a screw head and a shaft that extends from the screw head. The screw housing defines a longitudinal axis and a bore that extends along the longitudinal axis. The screw housing includes a basewall and opposed sidewalls that extend from the basewall. The basewall defines a notch that receives the shaft to increase pivotal movement between the screw and the screw housing relative to the longitudinal axis of the screw housing. The opposed sidewalk define a rod-receiving channel. The screw housing defines a transverse hole in communication with the bore. The spring is supported in the transverse hole and extends therethrough. The spring extends into the bore to frictionally engage the screw head while the screw head is seated in the bore.

A transverse connector includes a cross member connecting assembly, and first and second spinal rod connection members rotatably coupled to opposing end portions of the cross member connecting assembly. The cross member connecting assembly includes a first band slot defined therethrough and a threaded opening extending through an upper surface of the cross member connecting assembly and into the first band slot. The cross member connecting assembly includes a band set screw threadingly engaged with the threaded opening and movable relative to the first band slot.

A transverse connector system having a first and a second locking head, and a transverse rod that is secured by the first and second locking heads. The first and second locking heads are provided with a first and second pivot arm for engaging and securing first and second elongated rods. The first and second locking heads each simultaneously engage and secure the transverse and elongated rods separately.

A connector includes a first receiver that defines an implant cavity and includes a mating surface. A second receiver attachable with the first receiver via a flexible element, the second receiver defines an implant cavity and includes a mating surface engageable with the mating surface of the first receiver to fix relative orientation of the receivers. A biasing element is disposed adjacent the mating surfaces to space the mating surfaces such that the first receiver is movable relative to the second receiver in operation of the connector. Systems, surgical instruments, implants, spinal constructs and methods are disclosed.

A spine stabilization implant includes a first portion having a first fixed angulated extension, a first rod receiving element and a connecting element. The implant also includes a second portion having a second fixed angulated extension, a second rod receiving element, and a receiving portion for receiving the connecting element of the first portion. The second portion is configured with a locking assembly for locking the first portion and second portion to one another.

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.

Apparatus and devices for adding an additional spinal construct in a patient are disclosed. In one arrangement the additional spinal construct extends an existing spinal construct ipsilaterally with an inline rod connector in a minimally invasive or preferably, percutaneous procedure. In another arrangement, the ipsilateral extension of an existing spinal construct uses an offset rod connector for receiving an additional spinal rod that may be placed interiorly or exteriorly of the existing spinal construct.

The screw housing defines a longitudinal axis and a bore that extends along the longitudinal axis. The screw housing includes a basewall and opposed sidewalls that extend from the basewall. The basewall defines a notch that receives the shaft to increase pivotal movement between the screw and the screw housing relative to the longitudinal axis of the screw housing. The opposed sidewalls define a rod-receiving channel. The screw housing defines a transverse hole in communication with the bore. The spring is supported in the transverse hole and extends therethrough. The spring extends into the bore to frictionally engage the screw head while the screw head is seated in the bore.
