The Western Front, 1914-18: Advances in Surgery and Blood Transfusion
The scale of casualties on the Western Front pushed British military medicine to develop and adopt new treatments faster than in peacetime. The Thomas splint, designed originally by Hugh Owen Thomas and popularised for military use by his nephew Robert Jones, immobilised a fractured femur during transport, stopping the broken bone ends grinding together and greatly reducing blood loss, pain and shock; its widespread adoption from around 1916 cut the death rate from this type of fracture dramatically. Blood transfusion became far more effective once blood groups, discovered before the war by Karl Landsteiner, could be matched to avoid dangerous reactions, and once sodium citrate was used as an anticoagulant to stop donated blood clotting, which meant blood could be stored rather than needing a donor present at the moment of transfusion; by 1917 the American doctor Oswald Robertson had set up an early blood bank at a casualty clearing station, storing citrated blood on ice ready for use. X-rays, including mobile units brought close to casualty clearing stations, let surgeons locate shrapnel, bullets and fractures before operating, while the American neurosurgeon Harvey Cushing developed improved techniques, including the use of magnets, for treating head wounds, significantly reducing the death rate from brain injuries.
Before you start
Make sure you're comfortable with these topics first:
Method
- Learn the Thomas splint's function precisely: it immobilised a fractured femur (thigh bone) during transport, preventing the broken ends grinding together, which reduced blood loss, pain and the risk of fatal shock.
- Learn the two names linked to the Thomas splint and their different roles: Hugh Owen Thomas originally designed it for civilian orthopaedic use, and his nephew Robert Jones promoted its wider military adoption during the war.
- Learn the two separate breakthroughs behind wartime blood transfusion: Karl Landsteiner's pre-war discovery of blood groups, which allowed compatible matching to avoid dangerous reactions, and the wartime use of sodium citrate as an anticoagulant, which stopped stored blood from clotting.
- Learn why sodium citrate mattered so much: it meant blood no longer had to be transfused directly from a donor standing beside the patient, since citrated blood could be collected, stored and transported for use later, exactly when casualties were heaviest.
- Learn Oswald Robertson's specific contribution: by 1917 he had set up an early blood bank at a casualty clearing station, storing citrated blood on ice so it was ready in advance of an expected battle.
- Learn the two named advances in surgery: X-rays, including mobile units, let surgeons locate shrapnel and fractures precisely before operating, and Harvey Cushing's improved techniques for treating head wounds, including using magnets to remove metal fragments, significantly cut the death rate from brain injuries.
Worked example
Explain how the introduction of sodium citrate changed blood transfusion on the Western Front.
- State the problem sodium citrate solved: donated blood normally clotted quickly, which meant transfusion had to happen directly from a donor to a patient at the same time.
- State what sodium citrate does: added to donated blood, it acted as an anticoagulant, stopping the blood from clotting.
- State the practical consequence: blood treated with sodium citrate could be collected in advance, stored and transported to wherever it was needed, rather than requiring a live donor on hand.
- Link this to Oswald Robertson's development: by 1917 he used this to set up an early blood bank at a casualty clearing station, storing citrated blood on ice ready for use.
- State the overall answer: sodium citrate turned transfusion from an immediate, donor-dependent procedure into one that could be planned for and supplied in advance of expected casualties, saving many more lives during major battles.

Q1What injury was the Thomas splint designed to treat?Show answer
Answer: A fractured femur (thigh bone).
Q2Name the two men linked to the Thomas splint and their different roles.Show answer
Answer: Hugh Owen Thomas, who originally designed it, and his nephew Robert Jones, who promoted its wider military adoption.
Q3Who discovered blood groups before the war, making safer blood matching possible?Show answer
Answer: Karl Landsteiner.
Q4What did sodium citrate do to donated blood, and why did this matter?Show answer
Answer: It stopped the blood from clotting (acted as an anticoagulant), which meant blood could be stored and transported rather than needing a donor present at the time of transfusion.
Q5What did Oswald Robertson set up by 1917, and where?Show answer
Answer: An early blood bank at a casualty clearing station, storing citrated blood on ice ready for use.
Q6How were mobile X-ray units useful to surgeons at or near casualty clearing stations?Show answer
Answer: They let surgeons locate shrapnel, bullets and fractures inside a wound precisely before operating, without needing to send the patient further back for imaging.
