Changes in peripheral nerve fibres distal to a constriction

      Continued constriction of the tibial nerve of the rabbit by a ligature was accompanied by a reduction in maximal motor conduction velocity distal to the ligature, and by a reduction in axonal and total fibre diameter. From the presence of paranodal demyelination and distal fibre degeneration in severely affected nerves, it is suggested that in some instances the change in axonal calibre was part of a progressive distal atrophy which could lead to secondary demyelination and ultimately to “dying-back” of the affected axons.
