Clavicular fracture

In anatomical kinesiology, we have been discussing the upper extremity, and a common upper extremity injury is a clavicular fracture. The clavicle, or collarbone, connects the shoulder to the sternum. The clavicle is among the most frequently fractured bones in sports. There are three main mechanisms of injury: 1) falling on an outstretched hand, in which the force from the ground is transmitted up the arm and through the clavicle 2) falling onto the tip of the shoulder, and 3) a direct impact to the clavicle. Tony Romo recently fractured his left clavicle when he was hit after throwing a pass and landed on the tip of his left clavicle (you can view the video here). During the Mississippi State-Ole Miss game Saturday night, MSU receiver Chad Bumphis fractured his clavicle after diving to catch a pass and landing on the tip of his shoulder (no video available, but you can read about it here). When I was an athletic trainer at Auburn, one of our wide receivers fractured his clavicle in much the same manner during practice. He dove to catch a pass and landed right on the tip of his shoulder. The recovery time for most clavicular fractures is approximately 6-8 weeks, although each injury and person is different. A suspected clavicular fracture has to be initially treated as a major medical emergency, because the subclavian artery and vein, in addition to the brachial plexus (a group of nerves) run right behind clavicle, and it is possible for a piece of the clavicle to disrupt the artery, vein, or nerves. Most clavicular fractures will heal on their own, but sometimes surgical fixation is required.

Power Balance: Helpful or a Gimmick

Balance. Strength. Flexibility. This is the reported benefits a person gains from wearing the Power Balance bracelet. However, many people, including myself and some colleagues at Mississippi State, are very skeptical of these claims. First, how do these bracelets improve balance, strength, and flexibility? Second, when you watch the demonstrations of the tests on their website, the tests in which the athletes wear the bracelets is always performed second. This creates what is known as an order effect, in which a person performs better on a test the second time they attempt it. We had even discussed conducting scientific testing on the Power Balance bracelets. Well, it seems researchers at the University of Wisconsin at LaCrosse beat us to it. They tested 21 athletes wearing both the $30 Power Balance bracelet and a $.30 placebo plastic bracelet performing similar tests to those found on the Power Balance website. They found no difference in performance between the Power Balance trials and the plastic placebo trials (neither the participants nor researchers knew which bracelet they were wearing). They did find an order effect, in which participants did perform better during the second trial regardless of which bracelet he or she was wearing. So, what does this mean? The Power Balance bracelet does not improve balance, strength, or flexibility. Why spend $30 on a bracelet when a $.30 bracelet will give you the same results?
