Lactide-containing polymer and medical material

Bone-treating devices made of biodegradable polymers having a high-density and a high-orientation along the major axis, which have a density of 1.260 g/cm.sup.3 or more (when measured by the sink and float method) and which possess the bending strength and the bending strength-retaining characteristic defined by the following equations:

Bone-treating devices and their manufacturing method

The invention provides an article for joining the pieces of a fractured bone, characterized in that the article is composed of a high-molecular weight material which is absorbable in the living body and that the article is in the form of a tubular body having a hollow interior and a cutout extending over the entire length of the tubular body in the longitudinal direction thereof.

Bone-joining articles

A process for preparing a crack-free, dried collagen sponge having a shrinkage factor of up to 14%, including the steps of impregnating crosslinked collagen sponge with an aqueous solution of a hydrophilic organic solvent, freezing the sponge at a temperature of -80.degree. C. or lower, and vacuum-drying the sponge.
