An alignment verification device includes a spacer element and an alignme nt guide surface. The spacer element has proximal and distal portions and an insert engaging element disposed on the distal portion. The proximal portion can be of such a designed so as to serve as a handle for the verification device. The alignme nt guide surface is affixed to the spacer element and defines an alignment orifice. T he alignment orifice is spaced apart from the insert engaging element. A prosthesis is al so disclosed having an engaging element and a visual indicator element. The engaging element is configured to releasably engage the prosthesis engaging element of the alignment verification device so that, upon engagement, the alignment orifice is space d apart from the visual indicator element. The engagement of the alignment verification device with the prosthesis can thus be adapted to permit a sighting element of an image obtaining device to be aligned with the alignment orifice and the visual indicator element so that an image obtaining device is aligned with the prosthesis in a known orientation.
