Activity Level and Sport Type in Adolescents Correlates with Development of Cam Morphology

Video Transcription

Video Summary

The video discusses the relationship between physical activity and the development of CAM morphology in the proximal femur during skeletal maturation. It explains that high levels of physical activity during adolescence can cause the femoral physis to grow down the anterolateral femoral neck, creating a CAM morphology. The impact of physical activity on acetabular morphology is less understood. The study uses the Iowa Bone Density Study, funded by the NIH, to evaluate the role of activity level and sport type on both proximal femur and acetabular morphology in late adolescence. The findings show that higher activity levels predict higher alpha angles and lower head-neck offset ratios, indicating a development of CAM morphology. Power sport athletes are more likely to develop a CAM morphology compared to non-athletes, and there is no association between activity level and lateral center edge angle. The video suggests further study into sports diversification and specialization. The example images and measurements demonstrate the changes in alpha angles over time. The video credits the research of Klaus Siebenrock and Ward et al.
