Migration of Broken Hip Pin Into Urinary Bladder

To the Editor:— Foreign bodies in the bladder which have gained entrance through the urethra are not uncommon and an occasional sponge left in the abdomen has been recovered through the urethra. However, to have a 2-inch segment of a broken Hagie pin, which had been placed in the acetabulum, migrate into the bladder and be removed cystoscopically seems worthy of reporting. This white man, age 58 years, was in an automobile accident in December 1959. He had multiple injuries including a fracture of the right side of the bony pelvis which involved the acetabulum. One of his many surgical procedures included open reduction and an internal fixation of the right acetabulum with two Hagie pins entering the superior acetabulum and extending into the superior pubic ramus. The excretory urogram (Fig 1) is shown to illustrate the Hagie pins and the normal-appearing urinary tract. It was made in February 1960
