[Experimental single-stage reconstruction of the tendon sheath and flexor tendon (free tendon graft, using a vein for sheath on the flexor tendon in dogs)].
In dog experiments the flexor tendons of the 2nd toe together with their tendon sheaths have been extirpated by the authors. Then on the place of the tendon sheath complex-resembling the human hand's "no man's land" -for the substitution of the tendon sheath-free inautotransplants with long vein-segments have been grafted in one sitting. Resuming the results of the macroscopic and light microscopic examinations carried out in definite times it has been found by the authors that while the vein segment was revascularized in the course of one or two weeks, the regeneration of the tendon transplant was slightly retarded. Between the vein and the tendon but adhesion of medium degree were found. The possibilities of the clinical use of the method are discussed.
