Abstract: Bone graft retention devices, systems, and methods for retaining bone graft material at a desired site are described. The devices may attach to existing bone fusion systems or components thereof, such as rods or cross connectors, or may be integrated directly into a cross connector. The devices include a fin, and optionally one or more attachment elements. The bone graft material is attached to the fin, such as via an adhesive or by friction fit inside a cavity. Optionally, during insertion in a patient, the fin is flipped upwards so that it does not hinder the insertion. Following insertion of the rod or cross-connector in the desired location and tightening of the screws into their final positions, the fin of the bone graft retention device is flipped into place such that it aligns with the spine, pressing the bone graft material against the spine.

Abstract: Devices, kits, and methods for stabilizing the spine and replacing spinous processes removed during spine surgery are provided. The device has a suitable configuration to attach to both spine surgery hardware and to the paraspinal muscles and fascia. The device contains a muscle attachment portion, one or more connectors, and one or more cross connectors. Each cross connector contains a pair of connection portions configured to attach to hardware that is implanted in the spine, such as screw heads or rods. The muscle attachment portion contains a plurality of openings for the attachment of the paraspinal muscles and fascia. Following spine surgery, a surgeon attaches the device to the hardware implanted in the surgical site, and sutures the paraspinal muscles to the openings. Thus the device provides a direct attachment to the paraspinal musculature and fascia, and thereby stabilizes the spine.
