The report details progress made toward an active tendon prosthesis for the reconstruction of severely injured digital flexor tendon systems. Secure distal prosthesis attachment to bone may be either by bone ingrowth into a sintered titanium plug, or by screw fixation of a high carbon steel plate. High strength polyester fiber Dacron is the prosthesis shaft material of choice despite equally favorable biocompatability properties of Dacron and aramic fiber Kevlar. Impact energy of rapid muscle contraction will be absorbed by braided shaft design continuous with a proximal soft loop. The method for coating the prosthesis shaft with silicone rubber will be pressure molding, not dip coating. Studies of the strength, microcirculation, and biomechanics of the digital flexor tendon system were conducted using human cadaver hands. Author
