Abstract
A low profile rod-to-rod cross-connector formed from an outer bar member having a first end forming a receptacle and a second end available for coupling to a first spinal rod. An inner bar having a unidirectional insertion end is slidably insertable into the receptacle, and a second end is available for coupling to a second spinal rod; the insertion end having a centrally disposed slot bifurcating the insertion end. A locking member is positioned in the centrally disposed slot, wherein placement of the locking member in the first position permits movement of the insertion end within the receptacle, and placement of the locking member in the second position results in splaying the left arm and right arm to frictionally engage an inner sidewall of the receptacle.
