as connective tissue structural replacement or augmentation fig1 and 18 illustrate use of the basic laminate 18 to define sliding or slippery bearing surfaces in fig1 a cross section of a hand is shown wherein the wrist bones 98 are covered with a segment 100 of the pericardium mesh laminate with the mesh down so that it will bond to the bone and or periosteum the top surface of the laminate is the pericardium and just above this surface are the tendons 102 of the hand which are beneath the skin 104 by the utilization of the pericardium laminate between the bone and the tendons not only is a smooth surface defined which may eliminate problems with roughness occuring in the underlying bone but more importantly the growth of scar tissue around any tendon repairs above the bioprosthetic pericardium will not bond to the pericardium as it would to the underlying bone and soft tissue and thus will not limit the motion of the hand as would otherwise be a problem in hand reconstruction this implementation is similar in principle to that involving the pulleys 44 and 46 indicated in fig5 and 6 in both instances the mesh is used to form a firm tissue bond and the pericardium itself is used to define a sliding surface another sliding surface is defined in fig1 wherein an arthroplasty is performed on a joint 106 the joint may have become roughened or weakened.
