Researchers from IT Tralee, Bon Secours Hospital Tralee and Lero are collaborating on a project funded by Science Foundation Ireland to disrupt existing surgical practices by developing innovative robotic technologies for use in the hip replacement surgeries of the future. The €223,500 research project commenced in June 2018 at IT Tralee. The aim is to determine whether audio or vibrational resonances from the receiving femur can be utilised to develop a more accurate technique for surgeons to replace a hip joint. 

“Hip replacement involves the creation of a cavity in the femur canal into which the stem section is inserted,” says Dr John Rice, consultant orthopedic surgeon at Bon Secours Hospital Tralee. “This process is referred to as reaming. At the moment, surgeons use their skill and experience to determine the correct size of the cavity. Over reaming has the potential to fracture the femur which is why it will be a great step forward if we can use technology to objectively determine the correct size and tension of the cavity.” 

The project aims to deliver improved outcomes in hip replacement surgery, to minimise a patient’s hospital stay and avoid re-admittance due to complications arising from the operation.
