Development of a Tool for Component Positioning in THA Surgeries

More Info


Improper component positioning during total hip arthroplasties is the most common surgical error that takes place during the procedure. Though developments in the individual components have taken place, the positioning of these components during the surgery continues to be a challenge for surgeons, resulting in dislocations with a frequency between 1-10 % [1,2,3]. A practical and elegant solution in the form of a guidance tool was developed to be used by surgeons during placement of the acetabular cup component. The tool accounts for differing patient anatomy and patient position.
