CORE Turku Group

Center of Orthopedic Research Turku

CORE Turku is a research group operating at Tyks Orto, which was established in December 2022. The aim of the research group is to enable research at Tyks Orto, especially after the dissertation phase. In addition, CORE supports dissertation work. The research group focuses on RCTs and register-based research.

The research group is led by Associate Professor Inari Laaksonen and MD Elina Ekman

Research Group Leaders

Kuva henkilöstä
Inari Laaksonen, Assoc. Prof., MD, PhD

I graduated as a specialist in orthopedics and traumatology in 2021 and work as a orthopedic surgeon at Turku University Hospital. Alongside clinical work, I conduct clinical research broadly related to orthopedics and traumatology. I defended my doctoral thesis at the University of Turku in 2014 and then spent the year 2016-17 as a post-doc researcher in the USA at Harvard University. I received the title of docent in 2019 and since then have supervised four completed dissertations. Together with Elina Ekman, we founded the CORE Turku research group in 2022, and our goal is to enable research to be conducted in our clinic.

Kasvokuva Elina Ekmanista
Elina Ekman, MD, PhD

I graduated as a specialist in orthopedics and traumatology in 2018 and defended my medical doctorate in 2019. I completed the additional training program in traumatology in 2024. In my clinical work, I am responsible for the treatment of bone tumors in our University Hospital area, and I also treat trauma patients. Since my dissertation, I have continued to do research broadly in the field of orthopedics and traumatology extensively. In 2022, we founded the CORE Turku research group with Assoc. Prof. Inari Laaksonen to better promote and coordinate significant orthopedic and traumatological research in the Varha area.

Post-Doc Researchers

kuva henkilöstä
Ida Rantalaiho, MD, PhD

I graduated as a specialist in orthopedics and traumatology in 2020 and have since worked in the area of responsibility for spine orthopedics. I treat trauma patients on an emergency basis. I defended my medical doctorate in 2022 and at the beginning of 2024, I graduated from the spine surgery training program as a spine surgeon. After my doctorate, I have actively continued research work, focusing on my specialty of spine surgery, but also participate more broadly in research work in collaboration with other CORE research group members.

Kasvokuva Matias Hemmilästä
Matias Hemmilä, MD, PhD

I graduated as a specialist in orthopedics and traumatology in 2018 and defended my medical doctorate in 2021 on hip replacement revision surgeries. In my clinical work, I treat patients with osteoarthritis and perform hip and knee replacement surgeries and revisions. In addition, I treat trauma patients. The intention is to continue research on the treatment of joint replacement patients.

Ongoing Research Projects

Prospective Multicenter Studies

  • Limb injuries and post-injury rehabilitation trials – tibial shaft fracture (LIMPER-TSF)
    • The study is an ongoing, randomized, multicenter study comparing early full weight-bearing and early 6-week limb weight-bearing in patients whose tibial shaft fracture has been treated with intramedullary nailing. The goal is to determine the return to work and physical functional capacity after tibial fracture surgery with patients instructed to either early full weight-bearing or early limb weight-bearing.
