Fractured Clavicle

Scenario:
Fractured clavicle (collarbone) is a common mountain biking injury. In fact, the Green Valley (Bear Claw Poppy) Trail even has a slope named after this fracture: "Clavicle Hill." The fracture results from a direct hit on the outer side of the shoulder, such as an endo in which the biker turns to the side as he rotates forward.

Description:
A fractured clavicle (collarbone) is usually caused by falling directly onto the shoulder. There's pain in the middle of the collarbone, and often a deformity. The shoulder can't be moved fully.

Immediate care:
If you suspect a fractured clavicle, you should go to the doctor or emergency room. A temporary sling may keep the patient more comfortable during the hike out. Apply a cold pack directly over the deformed area of the collarbone.

Ongoing care:
A broken collarbone usually takes about 4 weeks to heal. Follow your doctor's instructions.
