Rationale of CIRRO
Clinical research is compared to basic research, often dependent on imprecise methods. The number of patients needed to demonstrate a difference between two treatment methods is therefore large. In musculoskeletal research common methods like plain radiographs are imprecise for detecting healing of bone, loss of bone (osteoporosis), body-composition and movement of implants or positions of joints. During the last decades more precise methods have been developed1. We have established a centre for radio-stereometric analysis (RSA) and dual energy x-ray absorptiometry (DXA). With RSA small movements of implants or joints can be measured with a precision of less than 0.1 mm for translation and 0.3° for angular movements. With DXA bone remodelling and body composition can be measured precisely within a few percent.
What do we do?
Goals for CIRRO for the next funding period:
“To use and develop precise measurement methods (RSA, dynamic RSA and DXA) in musculoskeletal research.
To further develop CIRRO as the main centre, which can deliver these services to researchers in Helse Sør-Øst, including supervision to PhD candidates in all participating hospitals/institutions.
To study new treatments (implants, surgical techniques, biotechnology, interventions like physiotherapy) with precise methods so results can be available for the benefit of patients in a short time and with few patients included.
To study disease development (cartilage wear, bone loss, changes in body composition) together with other methods in order to gain insight into mechanisms for disease and eventual treatment.”
