UK scientist surgical robot will make hip operations so simple that even students can get good results. Usually, operations using chrome alloy to re-emerge the ball of the hip joint are difficult and require years of experience to perfect however untrained students using the robot for "virtual" operations have been able to achieve high levels of accuracy.

Up to 5,000 hip resurfacing operations are done each year and if hip bones are repaired imperfectly, wear and tear occurs, requiring patients to undergo further painful and expensive corrective operations. Students were able to carry out the procedure three times more accurately compared to when they used conventional methods to manually navigate the joint. Clinical trials of the device, called the Wayfinder, are currently being carried out at Warwick Hospital, Bath Hospital, Truro Hospital and the London Clinic.
