PURPOSE: To provide a fixing pin which can secure fixing force to a rib, which is adapted to join injured or broken rib parts to each other and fix the same in the case of an injury, a breakage and solution of continuity of the ribs. CONSTITUTION: A rib fixing pin uses moldings obtained by melt-molding and drawing polylactic acid, and the moldings are secondary-molded or cut to form a bow-like rod. The compressive flexural strength is 16.0×10<2> -25.0×10<2> kg/cm<2> , and the compressive flexural elastic modulus is 5.5×10<2> -24.0×10<2> kg/mm<2> . The fixing pin has such high strength. |
