Abstract

A minimally invasive spacer for positioning between vertebral members. The spacer is adjustable between a first orientation having a reduced size to facilitate insertion between the vertebral members. A second orientation has an enlarged size for contacting the vertebral members. The spacer includes linkages that are attached to a pair of plates. A pull arm is operatively connected to the linkages for adjusting the spacer from the first orientation to the second orientation. A indicator gauge indicates the height of the spacer.
