The purpose of this study is to analyze the MRI (Magnetic Resonance Imaging) findings of skiing or snowboarding related injuries, with a special interest in the soft tissue (ligaments & cartilage) and bone contusion (bruising) patterns associated with various types of falls (mechanisms of injury). A small number of studies in the last 10 years have reported specific anatomic regions of bone contusions in patients that sustain serious injury, such as anterior cruciate ligament (ACL) tears. These bone contusions include compression injury to the articular cartilage and underlying sub-chondral (below the cartilage) bone. Several investigators have suggested that these bone contusion patterns may contribute to the development of degenerative arthritis over the following decades. A previous study done at Boise State demonstrated differences in bone contusion in skiers compared to other athletes with ACL tears.
This study will attempt to identify associations between the mechanism of injury, and the injured structures identified on MRI scans. This study will be a prospective design. Our hypothesis is that different injury mechanisms will be associated with unique, mechanism specific, injury patterns identified on an MRI. These injuries and bone contusion patterns will be subsequently analyzed and cataloged. Although several different mechanisms of skiing injuries have been described, this study will look for different contusion patterns, to provide insight into the underlying mechanisms of injury, and look to identify specific patterns associated with different age, gender, or activity groups.
We intend to use this research to develop a better understanding of the mechanisms of njury in skiers and snowboarders. This information will be useful in the development of new methods to train skiers/snowboarders during the off-season and may lead to changes in equipment design that reduce the risk of injury such as anterior cruciate ligament tears.
