There are two main types of headless compression screws available on the

market. One is a "herbert" style screw that has threads at the leading end,

a smooth shaft, and threads at the trailing end or head of the screw. The

other type is similar to the Arthrex compression FT screws that is fully

threaded with variable thread pitch to gain compression. True or False. The

main advantage to using a fully threaded screw with variable pitch is to gain

purchase along the entire length of the screw rather than depending on the
