Method and apparatus for replication of angular position of a humeral head of a shoulder prosthesis

摘要: A jig for trialing a head and conjoining portion of humeral (shoulder) prosthesis transferring the spatial positioning to final implant allows surgeon adjust position thereof in three-dimensional space with respect component that has been either previously implanted into humerus patient or not. The utilizes rotatable body such as sphere is non-translatable relative body. trial construct, having neck fixed one another (is spatially positioned), placed contact sphere. As caused align markings on situated flush jig, replicates angular head. construct whose components are not another, which automatically transfers construct.
