Publication number: 20060224240Abstract: A spacer for inserting between vertebral members. The spacer has a non-spherical shape with an anterior section having a first shape and a posterior section having a different shape. An attachment means is positioned within the posterior section, and may include a receiver for attachment with an insertion device, and an anti-rotation mechanism for assistance in removing the spacer from the insertion device. Embodiments of using the spacer is also disclosed which may include inserting the spacer between the vertebral members in a generally posterior approach. Once inserted, the insertion device acts with the anti-rotation device to remove a connection mechanism from the receiver. The spacer remains between the vertebral members and provides relief to the patient.Type: ApplicationFiled: April 4, 2005Publication date: October 5, 2006Inventors: Randall Allard, Robert Rice, Mark Dace
