The clavicle, commonly known as the collarbone, is a long, slender bone located between the sternum (breastbone) and the scapula (shoulder blade). It plays a crucial role in connecting the arm to the body and helps stabilize the shoulder. The clavicle is one of the most commonly fractured bones due to its position and exposure. Anatomically, the clavicle has two ends: the medial end, which connects to the sternum, and the lateral end, which connects to the scapula. It is shaped like an "S" and is important for the movement and support of the upper limb. Proper function of the clavicle is essential for activities such as lifting and reaching.
