  It is investigated the effects of rotation on the scalar field in the
spacetime with the distortion of a vertical line into a vertical spiral. By
analysing the upper limit of the radial coordinate that stems from the effects
of rotation and the topology of the defect, it is considered this upper limit
of the radial coordinate as a boundary condition analogous to a hard-wall
confining potential. Then, it is obtained a relativistic spectrum of energy in
a particular case. In addition, it is analysed a relativistic analogue of the
Aharonov-Bohm effect for bound states.
