Neck & Shoulder

What It Is

The collarbone (clavicle) is one of the main bones of the shoulder. It is the bone that connects the arm to the body, running between the breastbone and the shoulder blade (scapula) (American Academy of Orthopaedic Surgeons, n.d.). The collarbone helps provide strength and stability to the shoulder. It also lies over, and helps protect, important nerves and blood vessels (American Academy of Orthopaedic Surgeons, n.d.).

Broken collarbones are usually caused by a direct blow to the shoulder, such as a fall onto the shoulder, a car accident or a sports injury, or by a fall onto an outstretched arm (American Academy of Orthopaedic Surgeons, n.d.). This often happens in contact sports like wrestling, football, rugby or ice hockey. It is one of the most common bony injuries (Sherwood Forest Hospitals NHS Foundation Trust, 2026), and it can happen at any age.

Clavicle Fracture Anatomy

The collarbone (clavicle) is a slightly curved bone connecting the breastbone (sternum) to the acromion of the shoulder blade. The shoulder joint provides movement between two of the main bones: the scapula and the humerus (upper arm bone). The shoulder joint is a ball and socket joint: the shoulder blade provides the socket for the ball-shaped head of the humerus. Muscles and ligaments work to stabilise the joint during weight-bearing activities and movement.

The clavicle is connected to the scapula at the acromion, which is a bony projection extending from the scapula. This joint, the acromioclavicular (AC) joint, is surrounded and secured by the acromioclavicular ligaments.

When you have a clavicle fracture, one of the key things the hospital will check is whether the fracture is displaced, i.e. whether the broken ends have moved out of line, or whether they have stayed lined up so the bone can re-join. Many broken collarbones, especially those in the middle of the bone, heal without surgery. If the broken ends are very displaced, surgery may be recommended (American Academy of Orthopaedic Surgeons, n.d.), but the NHS says surgery is rare (NHS, 2023).
