Surgical Robot Improves Hip Surgery Success Rates

News on IT in Healthcare
Generally, surgeries that involve using chrome alloy to resurface the ball of the hip joint are extremely difficult and need years of experience to perfect.
However, using the new technology for ‘virtual’ operations, even untrained students were able to achieve high levels of accuracy.
Researchers said that inexperienced surgeons often face a steep learning curve to gain the experience necessary to carry out hip resurfacing operations. Until now, this has only been gained through repeatedly performing the operations.
This can cause problems because if hipbones are repaired incorrectly wear and tear occurs, requiring patients to undergo further painful and expensive corrective operations.
In order to demonstrate how easy the new technology was to use, the researchers studied 32 medical students doing operations on a model of a hip joint.
Developed by PhD students at Imperial College London, the Wayfinder is similar to GPS navigation systems; it senses the movement of the surgical tools and compares it to detailed images of the bones.
It therefore enables surgeons to see a ‘real-time’ virtual model of the progress of the operation.
The robot then plots where surgical incisions should be made and calculates the correct angles for inserting chrome alloy parts needed to repair the hipbone.
In the study, it was found that students were able to carry out the procedure three times more accurately compared to when they used traditionsl methods to manually navigate the joint.
