    摘要： A resilient core is positioned between bony projections which are offset from a principal load bearing region of a spinal joint. Shaped projections extend from the core, and engage the bony projections by conforming to anatomical landmarks, and may be fastened to the bony projections. During flexion of the joint, the core absorbs some of the force of compression, and limits an extent to which the joint may compress. If the shaped projections are connected to the bony projections, extension of the joint is inhibited by the projections and the core, limiting the extent to which the joint may be distracted. In this manner, healing is fostered, and a weakened or damaged joint is protected from excessive movement.

    摘要： An apparatus for distributing the load caused by the insertion of a fastening device into bony tissue is disclosed. In one embodiment, the apparatus comprises a crown having a plurality of protrusions. The protrusions may have any desired physical properties, and function to obtain purchase in the bony tissue. Preferably, the crown includes an opening that is selectively engageable with a spherical head of the fastening device. The opening preferably comprises a spherical curvature that allows the surfaces of the spherical head and the opening to maintain flush contact, even when the fastening device is inserted into the bony tissue at a non-orthogonal angle. When the fastening device is inserted into the bony tissue, the crown distributes the load over a wider section of the bone, allowing the bone to maintain its structural integrity.
