From: Torsional stability of interference screws derived from bovine bone - a biomechanical study
Pairwise comparison of the effect of the screw diameter on maximum breaking torques of BC interference screws in polymethyl methacrylate resin and p-values (Jonckheere-Terpstra trend test). There is a statistically significant difference between 7 mm screws and the two larger screw types. Statistically significant differences between 8 mm and 9 mm BC screw could not be found
