Pragmatic Research in Orthopedics - PRIO

Hip prosthesis in titanium with bone ingrowth Thor Balkhed

PRIO focuses on biological, mechanical and pharmacological aspects of fracture healing and implant osseointegration. Our translational approach aims to understand and explain complex clinical problems to improve decision making and thereby patient care.

Introduction

Hip prosthesis in titanium with bone ingrowth. Photo credit Thor BalkhedBone is a unique tissue with the capacity to regenerate itself through true tissue regeneration by reactivation of embryonal processes. Implant fixation and healing of fractures are inherently related to each other on a biological level but often separated from each other in the minds of orthopedic surgeons. We are orthopedic surgeons with an interest in joint replacement and fracture treatment, anesthesiologists, radiologists, biologists, movement scientists and others working together with national registries, the industry and academic collaborators around the world.

Photo credit Thor BalkhedOur main focus is to improve the survival of first- time joint replacements through bone specific drugs and to improve outcome after complex joint revision surgeries with the use of morselized bonegraft, detailed pre-operative planning and evaluation of specific surgical techniques. We are interested in the pathomechanisms behind stress fractures, specifically atypical femoral fractures, the treatment and evaluation of healing and avoidance of early and late complications through implant choices guided through biomechanical understanding. Only then can we improve day-to-day practical decision making.

An acute compartment syndrome (ACS) is a condition of increased muscular tissue pressure often caused by a fracture. The increased pressure leads to impaired circulation which, if left untreated, causes devastating consequences. Unfortunately, the diagnosis is difficult since the predominant symptom of ACS is pain which can be very difficult to differentiate from pain caused by a fracture. A need for an objective tool is therefore most welcome. The aim of our research is to investigate whether biomarkers could be this aid.
There is also an exertional form of compartment syndrome. Here we investigate if there is difference in tissue composition among affected patients and if ultrasound can be used as a tool for compartment pressure measurements.

BioFACTS logotype - a research project within the research group PRIO.

BioFACTS

The BioFACTS study is a prospective multinational, multi-centre study involving patients with tibial fractures. The project was designed by Ass. Prof. Jörg Shilcher at the Linköping University hospital and started recruiting in 2019. After expanding to several hospitals in Sweden, it arrived at the rough shores of Finland in the early 2020 with the first patient being recruited in January 2021.
