Orthopaedics - Sari Ponzer
Sari Ponzer's research group in orthopaedic traumatology focuses on osteoporosis related fractures and psychosocial factors affecting outcome after injuries. During the last years they have broadened their research area and have continually carried out clinical and epidemiological studies also on other types of injuries/diseases of the musculoskeletal system.
Research group leader
Wrist fractures are common and the treatment is controversial. The interpretation of the outcome of the various treatment procedures is complicated by the wide range of patient expectation, from the young and active to the sedentary and non-active patient.
The research group is running three randomized trials to compare different fixation techniques and different anesthetic methods. The patients are followed, evaluated and compared utilizing modern Health-Related Quality of Life (HRQOL) instruments together with clinical outcome measures.

Recovery after whiplash injuries of the neck
The associations between genetic factors, insurance company involvement and radiological factors and the risk of non-recovery after trauma are poorly investigated nor understood. In several studies on patient cohorts with traffic accidents, the research group investigates the relationship between different factors associated with recovery after injuries. The aims are to identify people with acute whiplash injuries who are at risk for non-recovery. The group is also performing a RCT to investigate whether an intervention in the form of an information film can result in better recovery.

Anterior cruciate ligament (ACL) reconstruction
ACL injury is a common sports related injury where the patient will experience instability of the knee joint which may prevent sporting activities. ACL construction is a common procedure to remedy this.
The research group runs several studies focusing on the methods and timing of ACL reconstruction as well on osteoarthritis following ACL-reconstruction.
