Development and Application of a Tendon Prosthesis for Early Functional Restoration of the Hand.
Abstract
Experiments were carried out to determine the feasibility of using stainless steel woven fiber tape for distal attachment to bone. The steel tapes were placed in 5 mm osteoperiosteal bone flaps. Forty-eight samples remained in for 4, 8 and 12 weeks. They were studied by tensile testing and histological examination. Tape shearing was irregular leaving fibers imbedded in bone. It was concluded that 316 L material approached 50% initial strengths. It would be necessary to make tape fiber textile rearrangements to improve porosity and again the study showed that 304 stainless steel was not acceptable. Porous metal ingrowth study should be continued. The proximal end attachment study was continued in the soft tissues of dog muscle and tendons. New materials were studied using DuPont Fiber B and paralytic graphite fiber. Various types of tape configurations are being studied to permit silicone surface attachment and porosity for tissue ingrowth.
