Dear EHS Members,

New treatment approaches and new recommendations for the optimal therapy of diseases are emerging daily, often involving considerable costs, and require a reliable scientific basis for evaluation. We can only overcome this challenge by working together. Therapy recommendations that were correct 10 years ago need to be completely rethought today. For example, with the ever-increasing durability of endoprostheses, the importance of joint-preserving surgery on the hip joint has changed, but it is undoubtedly still extremely important.

We have also learned that treatment methods cannot simply be transferred between countries; different approaches have led to different decisions about what is the optimal treatment for patients.

So my goals as president of the EHS are threefold:

First, I want to support bundling European scientific knowledge to further strengthen our society’s self-confidence on the international stage. Second, we have to develop more intensive International cooperation with North America as well as Asia. Rapidly developing countries like Thailand, Indonesia, and South Korea need more attention.

Third, we need to develop new young hip surgeons. This should be achieved through fellowships at renowned European hip centres and structured educational courses for systematic improvement of knowledge across EHS member countries.

I want to work together with you to make the EHS more and more attractive and visible, especially for these younger colleagues. To achieve this, I want to work closely with the current President Fares Haddad, the Executive Committee, and with National Reps and all Members of the Society.

Simon Steppacher

I am a hip surgeon at the Department of Orthopedic Surgery and Traumatology at Insel hospital in Bern, Switzerland. My research is dedicated to hip joint-preserving surgery, aiming to enhance our understanding of hip pathologies and optimize surgery to improve patient outcomes. The Insel hospital has a long-standing tradition in hip joint-preserving surgery and provides an excellent research environment. I collaborate closely with computer scientists and radiologists to advance imaging techniques and develop innovative computational methods for a deeper understanding of hip biomechanics. As a proud member of the EHS SciCom, I look forward to contributing my expertise and helping to organize an outstanding congress and education to advance hip surgery.

Andrew Manktelow

Consultant Orthopaedic Surgeon
Nottingham University Hospitals NHS Trust (UK)

Trained at Royal National Orthopaedic Hospital, I have a primary, complex primary and revision hip practice in Nottingham. My arthroplasty interest was developed during a year in Boston, at MGH.

My clinical work provides research opportunities and forms the basis of my educational activities. I travel widely to demonstrate my practice, setting up the Nottingham Revision Course in 2007. Our Revision Network, providing a forum for different hospitals to meet ‘virtually’ to plan complex cases, has received international attention.

I am active in implant development, part of a worldwide development team, I performed the first implantation of a now-established socket system in Nottingham in 2009. I am involved on ongoing development with a ceramic hip resurfacing, alongside other primary and revision hip projects.

President of the British Hip Soc in 2018, I was voted onto the BOA Council in 2019 and remain on Council to the present. I became a member of the International Hip Society in 2018 and have recently become the UK National Representative for the European Hip Society. I look forward to furthering the interactions between UK and European Hip Surgeon colleagues. I hope my work within the EHS SciCom will contribute to that goal.

I have little time to spare away from my work, though when quiet, I enjoy travelling, music, gardening, (watching) sport and planning future revisions.
