Research is undertaken into patient satisfaction related to back disorders, shoulder instability and the results of varying shoulder procedures. In recent years, two hip prostheses, one knee prosthesis and a shoulder prosthesis have been developed in conjunction with industry. Fundamental research into the cement cape surrounding hip prostheses is also being conducted jointly with the Radiology Department, the Faculty for Applied Sciences and two research groups abroad. Ultimately, the Department is involved with several multicentre studies into new medication, such as that concerning the prevention of deep vein thrombosis, commissioned by pharmaceutical companies.
