If you heard English in Berlin at DKOU (the German Congress of Orthopaedics and Traumatology, and the biggest ortho congress in Europe with over 8,000 attendees) coming from one of the lecture halls, it must have been the EHS session, organised and chaired by EHS President Elect and Nat Rep for Germany, Prof Carsten Perka, with EHS Past President, Prof Eleftherios Tsiridis co-moderating. This year we presented on:-

• Prof Klaus Siebenrock: Did diagnosis improve and how with modern MRI techniques?
• Prof Rüdiger von Eisenhart-Rothe: AI for planning & execution in osteotomies
• Prof Fares Haddad: New diagnostic tools to prove/exclude PJI?
• Prof Eleftherios Tsiridis: STAR piriformis preserving MIS posterior approach: is the way forward?
• Dr Sebastian Hardt: Short stems – a significant step forward in case of revision?

It was a very inspirational session with excellent discussions. Thanks to everyone who attended.

The session will be available for replay soon. Watch this space.

Also during DKOU, EHS was very proud to see our President 2016-2018 Prof Wim Schreurs receive the Hans-Georg Willert Award and deliver a great presentation: About young patients, biological reconstructions & long-term follow-up in THA. A worthy tribute to an outstanding leader and academic.

EHS would like to thank the DKOU team for all their help with organising the EHS booth in the exhibition hall, where we were able to meet many new hip surgeon and hip research faces and spread our EHS philosophy of “bringing hip surgeons together to improve patient care”.

The Hip Symposium Bern successfully attracted a new record of close to 300 participants this year! The meeting was co-organized by the EHS with significant scientific contributions from EHS faculty.

One of the highlights was a live commented pre-recorded surgery. A severe epiphysiolysis of the femoral head was treated by a modified Dunn procedure. Respecting the pedicle for the blood supply to the head, the epiphysis was completed separated from the femoral neck and anatomically realigned.

The guest of honor was Richard Santore, Professor of Orthopaedic Surgery at the University of California, San Diego. Enthusiastically he taught us about “The Keys to Happiness in Life & Career”. Other highlights included video sessions about surgical techniques around the hip and lively case discussions. The Symposium was rounded up sessions comprising “Glimpses into the Future” and “Glimpses into the Past”. We all had a wonderful social dinner in a cordial and warm atmosphere at the Kornhauskeller.

Detailed information on https://www.hip-symposium-bern.ch

Soon also free replay of presentations and videos from Hip Symposium 2023!

Our next Hip Symposium is planned for April 10 – 12, 2025

Course organiser & EHS Member, Dr Luca Garro, reports: It was a great day! We talked about one of the major hot topics in hip replacement surgery over 4 sessions:-

• basic science
• primary implants
• trauma and young patients
• revisions

It was an opportunity for sharing, comparison and growth, attracting an international audience of 170 people. Experienced surgeons and young orthopedic surgeons alike. Together.

See you back in Rome in 2024!

The Vienna vibe was great weather and smiling faces for the 24th EFORT Congress in May 2023, as well as great science, of course.

Osteotomies Around the Hip – Hands On Cadaver Course at Nova Medical School, Lisbon

Dear EHS Members,

This practical course covered femoral and pelvic osteotomies from childhood to adulthood and involved orthopaedic surgeons and paediatric orthopaedic surgeons.

Two days of sharing knowledge, tips and tricks and practical skills on hip preservation with 16 participants from Portugal, Switzerland, Italy and Poland, networking and visiting sunny Lisbon.

In the cadaver lab the participants had the opportunity to perform a surgical hip dislocation, a femoral intertrochanteric osteotomy and a periacetabular osteotomy. We also had a sawbones session where the participants could execute pelvic and femoral osteotomies on paediatric sawbones.

We would like to thank Nova University and Ahead for the organization, our faculty for the expertise shared and send a special thank you to the European Hip Society and the European Paediatric Orthopaedic Society for their support and acknowledgement.

Kind Regards,

Dr Pedro Dantas, Nat Rep for Portugal

The 2022 FORTE Summer School in Athens was a great success. Between July 25-29, 114 Orthopaedics and Trauma trainees from 15 different European countries met 50 internationally renowned orthopaedic surgeons from all around Europe in a very productive course, enjoying the Greek hospitality.

All topics of the European Orthopaedics and Traumatology Curriculum were covered. A basic Comprehensive Review Course (CRC) provided general topic reviews through expert lectures, covering the basic knowledge. Additionally, a more advanced Exam Preparation Course (EPC) tried to address the educational objectives of more advanced trainees; those that are preparing themselves for National or European Exams.

Most of the European Subspecialty Societies embraced this course, while prominent members of their leadership were invited to Athens as faculty. The Hip Sessions of the Summer School were lead by EHS Committee Members, inlcuding EHS President Elect Prof Eleftherios Tsiridis and EHS SciCom Members Prof Klaus-Peter Günther, Prof Theofilos Karachalios and Dr George Macheras. Congratulations to FORTE President and EHS Member Dr Panayiotis Megaloikonomos and to the FORTE Summer School Committee for the excellent organization of this course and thanks to EHS once again for patronage.

We had to wait three years to come face to face once again, but it felt like yesterday to see colleagues all together in the familiar congress centre in beautiful Lisboa. As always, EHS is thankful for the booth supplied by EFORT and to all who stopped by to touch base.

Our events during EFORT were well attended.

As always, EHS had a booth at the EFORT annual congress, this year the 20th, which took place in Lisboa.

Thanks to all who attended the EHS Specialty Session on Innovations, New Trends & Outcomes in Hip Arthroplasty, and those who came upstairs to find the EHS booth and say hello.

The congress was a great success with attendance up a little but on last year, just shy of 6,000 participants from around the world.14th EHS Congress October 2021 in Lille 10-11th September 2021
