Abstract
Article made of lactic acid polymer capable of being employed particulaly as a biodegradable prosthesis exhibiting at 23.degree. C. a tensile regidity modulus higher than 5000 MPa and a tensile resilience higher than 500 kJ/m.sup.2 and a heat shrinkage of less than 50% at 130.degree. C. The article is produced by forging a blank at a temperature of between 80.degree. and 170.degree. C., with a draw ratio of 200 to 1000%.
