[Vesico-acetabular fistula following prosthesis migration].

A rare case is described of vesico-acetabular fistula following acetabulum displacement of a hip replacement towards the inner bladder, fourteen years after the original insertion of the prosthesis. In all the reviewed literature of we have not found a single described case of vesico-acetabular fistula associated with displacement towards the bladder interior of a hip prosthesis, which leads us to consider this complication an exceptional one.
