New thesis on hip arthroplasty
Henrik Dahlstrand from the research group Orthopaedics will defend his thesis "Evaluation of a metal-on-metal total hip arthroplasty" on February 10, 2017. Main Supervisor is Rüdiger Weiss.
What´s the main focus of your thesis?
We have for 17 years been following patients with a new model of total hip arthroplasty that became popular a decade ago and compared its outcome with a traditional model of hip arthroplasty.
Which are the most important results?
The new and the traditional prosthesis model show similar outcome regarding function and long-term survival. The new model however, increases the amounts of the metals Cobalt and Chromium in patients. These metals can be biologically active and our conclusion is that it's safer to use the traditional model since there are no apparent benefits of the newer model.
How can this new knowledge contribute to the improvement of people’s health?
Hopefully by preventing future use of orthopaedic implants that saturates the patients’ tissues with heavy metals without adding anything of value.
What are your future ambitions?
The same as always: to exercise more and eat more vegetables. But it will probably work out the way it usually does.
