Abstract
A system includes a sleeve including first and second arms each including an outer ramp and an inward projection, each of the arms defining a cavity. First and second extensions are configured for disposal in the cavities. A fastener includes walls defining an implant cavity and a distal portion. The walls each include first and second end surfaces and a locking cavity. The extensions are configured for translation relative to the sleeve between a first orientation such that the extensions engage the respective ramps to fix the projections with a respective locking cavity in a configuration to capture the fastener with the sleeve and a second orientation such that the extensions move out of engagement with the respective ramps so that the projections are movable out of engagement with the locking cavities to release the fastener from the sleeve. Methods of use are disclosed.
