On-mountain coverage of competitive skiing and snowboarding events.

Skiing and snowboarding are popular sports worldwide both for competitive and recreational participants. Medical coverage of the competitive events can be challenging because of the wide variety of competition styles and venues. Skiing and snowboarding have similar overall rates of injury, with lower extremity injuries more prevalent in skiing and upper extremity injuries in snowboarding.

Using suture anchors for coracoclavicular fixation in treatment of complete acromioclavicular separation.

For the repair of acromioclavicular separations, we describe a new method of securing the clavicle to the coracoid process using suture anchors. We have repaired 11 consecutive complete acromioclavicular separations in this manner with very good results. We find this to be an easy and reproducible method of anatomical fixation.

The effect of the menstrual cycle on anterior cruciate ligament injuries in women as determined by hormone levels.

Anterior cruciate ligament injury rates are reported to be two to eight times higher in women than in men within the same sport. Because the menstrual cycle with its monthly hormonal fluctuations is one of the most basic differences between men and women, we investigated the association between the distribution of confirmed anterior cruciate ligament tears and menstrual cycle phase. Sixty-nine female athletes who sustained an acute anterior cruciate ligament injury were studied within 24 hours of injury at four centers.
