Comparative Study
The dangers of snowboarding: a 9-year prospective comparison of snowboarding and skiing injuries.
We studied 2,552 snowboarding injuries and 5048 skiing injuries sustained during 1988-97. The number of snowboarding injuries had been increasing year by year and was 6 times as many as skiing injuries (2.0 versus 0.35 per 1,000 visits). The types of snowboarding injuries included fractures (39%), lacerations (21%), dislocations (17%), and contusions (15%). ⋯ In snowboarding accidents, the rates of fractures and dislocations were higher than those in skiing in almost every part of the body. Severe injuries were commoner in snowboarding accidents. We recommend the use of appropriate equipment and instructions for beginners to prevent such injuries.

We determined which angle of flexion best prevents popliteal artery injury during knee surgery. We took MRIs of the knee in the lateral position with the knee in 0 degrees, 45 degrees, 90 degrees, and 120 degrees of flexion in 15 volunteers. ⋯ More distally, no significant difference was noted with increasing flexion. Flexion of the knee may minimize injury to the popliteal artery in procedures between the level of the joint and 15 mm distal to the joint.
