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.
