摘要:
Spinal plates with additional features to improve the stability of the interface between the plate and the underlying bone. A bone plate may include one or more sharp ridges along the periphery of its underside. When attached to bone, the ridge digs into the bone and increases stability. A bone plate may alternatively or additionally include one or more holes for optional spikes, which may be inserted once the plate is attached to the bone. By separating the spikes and including them as an optional component, the plate may enhance stability while reducing or eliminating the chance of the spike injuring the patient. Furthermore, bone screws may incorporate alternating notches and ridges into the head of the screw. The notches and ridges may interface with a set screw, thereby preventing rotation and loosening of the screw.
