Prototype version of the Dobbie bone saw, England, 1967
The Dobbie bone saw was invented by Kenneth Dobbie for use in hip replacement operations. Dobbie had successfully applied for the patent rights to his invention in 1967 – one of the shafts is punched with “DOBBIE BONE SAW X3B 1967/ PROV PAT[ENT] 3700 67”. The modern hip replacement operation owes much to the work of John Charnley (1911–82), an orthopaedic surgeon during the 1960s.
