Bernhard Flatøy graduated MD from Medical University of Debrecen in 2007, and subsequently completed internship and 3 years of orthopaedic residency at Namsos Hospital. He is currently working as resident at the department of orthopaedic surgery at Ullevål university hospital.

The project consists of trials that investigate new implants in the field of cemented total hip arthroplasty, with special focus on stems with force closed fixation design and HXLPE acetabular cups. RSA is used as a method of investigation in all trials.
The project is set to be a part of a PhD degree.
3 trials are currently a part of this project:

  1. Migration pattern of a triple tapered stem. A prospective randomized study using RSA. 
  2. Changes in migration pattern after design modifications in triple tapered stem. A prospective randomized study using RSA.
  3. RSA study of wear and migration in Vitamin E stabilized HXLPE acetabular sockets.
