An anti-splay member is configured for engagement with a bone fastener and includes a body defining a longitudinal axis and a threaded cavity extending along the longitudinal axis. The cavity is configured for engagement with a screw. Opposing retainer members extend transversely from the body and are configured to engage a proximal end of the bone fastener to prevent radial expansion of the proximal end. At least one locking member extends from the body and is configured for engagement with the proximal end of the bone fastener. Methods of use are disclosed.
