A screw assembly and a spinal implant. The screw assembly includes a screw with a head and a shaft where a screw retention member is positioned beneath the head of the screw and substantially surrounds the shaft of the screw. The screw retention member is formed from a temperature-sensitive material. The screw retention member has a first contracted position adapted for inserting the screw through at least one hole in the spinal implant and a second expanded position adapted for retaining the screw within the at least one hole in the spinal implant. The screw retention member may be in the form of a coiled spring or a collar having a plurality of tabs.
