[Experimental 2-stage tendon and tendon sheath reconstruction in tendon sheath injuries].

The whole tendon sheath of hens were cannulated by a silicone rubber stick in a first stage and only the injured part of the tendon sheath was substituted by a autologous venous or fascial transplant. The tendon was reconstructed by a free tendon transplant in a second stage. The venous respectively the fascial patches revitalize within 2 weeks. Smooth slide faces originated on their inner surface. The adhesions between the reconstructed tendon sheath and the tendon were small in general. The healing of the tendon ran down without any disturbance.
