Patent attributes
An alignment system for aligning a reaming guide during insertion into a cavity of a bone is provided. The bone has a resected surface and the cavity defines a cavity axis. The system includes a reaming guide that includes an elongate stem portion having a stem axis, a neck portion extending from the stem portion at an incline with respect to the stem axis, and an alignment instrument. The alignment instrument includes a handle defining a handle axis, the handle being releasably couplable to the reaming guide such that the handle axis is in a predetermined relationship with the stem axis. The alignment instrument further comprises a plane finder slidably coupled to the handle, the plane finder comprising a surface defined by a plane that intersects the axis of the handle at an angle having a predetermined relationship with the angle at which a resection surface of the bone intersects the cavity axis.
