Abstract

This study compared cannulated 4.5-mm bioabsorbable screws made of self-reinforced poly-levolactic acid to cannulated 4.5-mm steel and titanium screws for resistance to shear stress and ability to generate compression in a polyurethane foam model of slipped capital femoral epiphysis fixation. The maximum shear stress resisted by the three screw types was similar (self-reinforced poly-levolactic acid 371±46 MPa, steel 442±43 MPa, and titanium 470±91 MPa). The maximum compression generated by both the self-reinforced poly-levolactic acid screw (68.5±3.3 N) and the steel screw (63.3±5.9 N) was greater than that for the titanium screw (3±1.4 N, P
