Abstract
This paper will seek to evaluate results obtained from mechanical testing and computational analysis to determine the efficacy of new thread designs for bone screws in their various applications and uses in surgical treatments. These new thread designs will be tested against the market standard buttress thread and any resulting trends will be analyzed.
Four different thread designs were tested in 90 degree cyclic loading and then subsequently an axial pullout test. The parameters of interest from these tests such as peak to peak displacement over cycle and axial load versus axial displacement were recorded. These four designs were the Osteocentric A and C designs, the Synthes buttress screw, and a buttress screw with a matching major diameter to the Osteocentric A and C threads
