The present invention provides a distal tip for the positioning of artificial joint stem that is capable of reliably guiding the insertion of the stem of the cementless artificial joint into a bone canal and positioning the distal end portion of the stem that is inserted into the bone canal at a planned position, thereby to maintain the entire stem in a favorable posture in the bone canal, and prevent osteolysis and loosening of the artificial join even when the distal tip is used. The distal tip 10 for the positioning of artificial joint stem is mounted near the distal end portion 2a of the stem of the cementless artificial joint thereby to guide the distal end portion 2a of the stem so as not to make direct contact with the inner surface of the bone canal 4 of the bone 3 when the stem 2 of the artificial joint is inserted into the bone canal 4, and make stable positioning of the stem distal end portion 2a when the insertion of the stem 2 is completed, wherein the distal tip 10 is made of a biodegradable and absorbable material.
A distal tip for the positioning of artificial joint stem that is mounted on a cementless artificial joint at a position near the distal end of the stem thereof and guides the distal end portion of the stem so as not to made direct contact with the inner surface of a bone canal when said artificial joint stem is inserted into the bone canal and, at the same time, achieves stable positioning of the distal end portion of the stem in the bone canal when the insertion of the step is completed, wherein said distal tip is made of a biodegradable and absorbable material.
