The method of designing and manufacturing the artificial joint stem,
comprising steps of performing analysis of the internal stress of the
artificial joint stem and bone and the adhesive stress of the artificial
stem and bone, using the computer, based on the three dimension data
indicating the structure of the bone formed by using plural tomographic
images of the bone, the design condition involving the form and stiffness
of the artificial joint stem configured by using at least one of the
tomographic images and the three dimension data, wherein if the result of
the analysis does not satisfy the design condition, the condition is
changed to have the computer reanalyze and if the result of the analysis
satisfies the design condition, the artificial joint stem is designed and
manufactured with the stem data based on the result of analysis and the
design condition.
