Mr. Specter. Which one?
Dr. Gregory. "A" is the one made before the wound was dealt with surgically.
Senator Cooper. Could you mark it 4 "A," "B," "C," and "D," Doctor?
Mr. McCloy. Is that "B," we have had another "B" here, you know?
Dr. Gregory. This is "C." "A" and "C" are comparable X-rays, one made before and one made after the operation was carried out.
Before the operation, you will note a large fragment of metal visible here, not visible in this one. You will also note a small satellite fragment not visible here. A second piece of metal visible preoperatively is still present postoperatively.
No effort incidentally is made to dissect for these fragments. They are small, they are proverbial needles in hay stacks, and we know from experience that small flakes of metal of this kind do not ordinarily produce difficulty in the future, but that the extensive dissection required to find them may produce such consequences and so we choose to leave them inside unless we chance upon them, and on this occasion, those bits of metal recovered were simply found by chance in the course of removing necrotized material.
Other than that the X-rays have nothing more to offer so far as the wrist is concerned.
Mr. Specter. May we then reserve 692 for "C" and 693 for "D"?
Dr. Gregory. I will put the other marks on these.
