The case reported demonstrates multiple complications of a fracture of the pelvis with central displacement of the hip, culminating in a bizarre cutaneo-osteovesical fistula two and one-half years after the original trauma.
Such fistulae following hip fusion produced by internal fixation or following hipnailing for fractures of the femoral neck are singularly rare.
The fistula in this case was demonstrated by injection of the cutaneous ostium but not by cystography.
The treatment of such fistulae should consist in adequate drainage of abscesses, removal of sequestra, establishment of adequate bladder drainage, and control of infection by chemotherapeutic and antibiotic agents.
