Abstract
A spacer for an artificial spinal disc arrangement is provided. The artificial disc arrangement includes an upper plate, a lower plate, and articulating surfaces between the upper and lower plates arranged to permit motion between the upper and lower plates. The spacer has a first surface for contacting the upper plate and a second surface for contacting the lower plate and is of sufficient thickness such that, when disposed between the upper and lower plates, the spacer limits motion between the upper and lower plates. An artificial disc, a method of limiting motion of an artificial disc in a patient, and a method of performing spinal disc surgery are also disclosed.
