Structural elements of biocompatible material are interlocked with one another in an array to repair, augment or replace natural bone, the structural elements each including a hub having a center, and a plurality of posts projecting from the hub and spaced from one another to establish inter-post spaces between adjacent posts, each post having a root at the hub, an opposite tip, a length, and a transverse cross-sectional configuration, the number of posts and the relative length, cross-sectional configuration, and location of adjacent posts in each structural element being such that the inter-post spaces of one structural element will receive the posts of adjacent structural elements in the array to promote interlocking of adjacent structural elements in a relatively tightly meshed relationship for resisting shear stress in essentially all directions within the array.

Interlocking structural elements and method for bone repair,

An adaptor is interposed between a socket in a ceramic femoral head component and a post on a femoral stem component in the femoral stem of a prosthetic hip joint to enable the use of a taper within the socket which is steeper than the taper on the post so as to reduce hoop stresses in the ceramic femoral head component while at the same time accomplishing securement of the ceramic femoral head component upon the post of the existing femoral stem component.
