  Topological effects of a spiral dislocation on an electron are investigated
when it is confined to a hard-wall confining potential. Besides, it is analysed
the influence of the topology of the spiral dislocation on the interaction of
the electron with a non-uniform radial electric field and a uniform axial
magnetic field. It is shown that a discrete spectrum of energy can be obtained
in all these cases. Moreover, it is shown that there is one case where an
analogue of the Aharonov-Bohm effect for bound states is yielded by the
topology of the spiral dislocation.
