Impact of war and technology on modern surgery
In World War I, a simple leg splint cut deaths from broken thigh bones from around 80% to 20%.

What followed
Rebuilding faces: the pioneers of plastic surgery
Both World Wars left huge numbers of soldiers with head and facial injuries that severely disfigured them. That demand drove plastic surgery forward fast. Tap a surgeon to see the move that mattered most.

What technology changed in surgery
Four technologies, one question for each: what did it change for the patient?
WHAT YOU'VE LEARNED
A quick recap of today's lesson.
Blood banks, a simple splint and rebuilt faces, set against X-rays, keyhole cameras and a £2 million robot.
What you need to know
- Blood loss was a major danger of surgery: lose too much and a patient could go into shock and die.
- Blood groups were discovered in 1901, blood could be stored from World War I, plasma research in World War II made larger blood banks possible, and since 1945 transfusions have been common in surgery.
- The Thomas splint (widespread from 1916) cut deaths from fractured femurs from around 80% to 20%; Gillies (1917) and McIndoe (World War II) developed plastic surgery for disfigured soldiers.
- X-rays and keyhole surgery made surgery less invasive; robotic surgery means less pain and shorter hospital stays but costs so much it is not always available; prosthetic and bionic limbs improved care after surgery.
- To judge war against technology, weigh them with a criterion: how many patients were saved, and how much each changed surgery.
The big picture
Two big forces have shaped modern surgery. War helped overcome the major problem of blood loss: blood groups were discovered in 1901, blood could be stored from World War I and moved more easily after World War II, and since 1945 transfusions have been routine. The wars also brought the Thomas splint, rebuilt faces through plastic surgery and put X-rays to work on a large scale. Technology has made surgery less invasive (X-rays, keyhole surgery), eased recovery (robotic surgery) and improved care after operations (prosthetic limbs). Judging which mattered more means weighing how many patients were saved against how much each changed surgery.
Key points
Worked example
Problem
Explain why plastic surgery developed so rapidly during the two World Wars.
⚠ Watch out
Giving war the credit for discoveries made in peacetime. X-rays were discovered in the 1890s and blood groups in 1901, both before World War I. What war did was put X-rays to use on a large scale and push blood storage forward.
Memory hook
War tackled the three Bs: Blood (blood banks), Bones (the Thomas splint) and Burns and faces (plastic surgery). Technology goes See, Shrink, Speed, Replace: X-rays SEE inside, keyhole SHRINKS the cut, robots SPEED recovery, prosthetics REPLACE the limb.
Check yourself
Blood groups were discovered in 1901, in peacetime. Does that weaken the claim that war helped overcome blood loss? Think about what still had to happen before blood was ready for an operation.
