A collection of nine instruments and associated attachments used for spinal surgery, developed by Henry Crock for his surgical technique of disc removal and inter body fusion, made by Trewavis Sergical, Australia, c. 1960
Henry worked with the instrument manufacturers, Trewavis Surgical Instruments of Melbourne Australia to devise a set of tools that were unique to his pioneering surgical method. An interbody fusion is a spinal fusion that involves removing a disc between the vertebrae. Once removed, an impact or spacer is put in its place. Prior to Henry’s development of these tools and his improvement of the surgical method, many surgeons who carried used bone cutters to removal spinal discs and make bone implants. As the cylindrical cutter in his tool set measured accurately both the diameter and the height of the implant, it was able to produce an implant which fitted precisely into the space prepared for it. This method ensured a better quality fusion of the bone and more comfort for the patient. Many other surgeons followed his methods and adopted his techniques.
Henry was born in Perth, Australia in 1929 and had a successful medical career in both Australia and the United Kingdom. His career focused mainly on the blood supply to the bones, an interest which was started whilst lecturing in orthopaedics at Oxford University. His name is etched into the tools which he used until he retired in 2001.
