摘要： A bone anchor assembly is provided, which may be used in cervical, thoracic, lumbar or sacral areas of the spine or other orthopedic locations. The anchor assembly includes a bone anchor, a receiver mounted to the bone anchor, a saddle within the receiver, a spacer within the receiver, and an engaging member. The receiver extends along a central longitudinal axis proximally away from the bone anchor. A rod or other elongated connecting element is received in a passage of the receiver in contact with the saddle, and the engaging member engages the connecting element against the saddle, which engages the saddle against the spacer, which in turn engages the proximal head of the bone anchor in the receiver. The orientation of the saddle in the receiver is adjustable to correspond to the orientation of the connecting element relative to the central longitudinal axis of the receiver.

摘要： Laterally expanding vertebral spacer devices are provided for repairing damaged vertebral discs. The vertebral spacer devices maintain the height of a distracted vertebral disc space while providing stability to the spine. In one form of the invention, a vertebral spacer device is provided with a first arm movably coupled to a second arm. The first and second arms are laterally expandable from a first width for insertion into the disc space to a second width after insertion into the disc space. The first and second arms also define a cavity therebetween for placement of bone growth material.

摘要： A spinal cage implant is adapted to be inserted in a damaged intervertebral disc for restoring the discal height and permitting an arthoesis. The implant comprises a central part with walls and terminal parts for bearing against the cortical bone of the vertebral end plates. The implant bears against the vertebral end plates with terminal parts and contains bone graft material between walls with an opening to permit bone fusion between the two vertebrae. The implant permits restoring the physiological lordosis and the intervertebral height.

The devices may include a body with a first face that contacts the vertebral member and a second opposite face. A hook may extend outward from the first face to engage the vertebral member. The body may also include one or more receivers to receive the elongated members. An engagement member may be movably connected to the body. The engagement member may include a first section that contacts the body, and a second section that includes a second hook. The engagement member may be positioned relative to the body to adjust a distance between the first and second hooks to attach the body to the vertebral member. A fastener may secure the engagement member to the body at the desired position. The fastener may also attach the one or more elongated members to the body.
