3. Clavicle Fracture
A clavicle fracture is also known as a broken collarbone. Clavicle
fractures are very common injuries in adults (2–5%) and children (10–
15%) and represent the 44–66% of all shoulder fractures. It is the most
common fracture of childhood. A fall onto the lateral shoulder most
frequently causes a clavicle fracture. Radiographs confirm the diagnosis
and aid in further evaluation and treatment. While most clavicle
fractures are treated conservatively, severely displaced or comminuted
fractures may require surgical fixation

4. Mechanism of Injury
1. Fall with arm out, onto hand

5. Mechanism of Injury
2. Fall onto shoulder

6. Mechanism of Injury
3. Direct blow to shoulder

7. Epidemiology
• Affect 1 in 1000 people per year
• Are the most common fractures during childhood
• Approximately two-thirds of all clavicle fractures occurring in males.
• There is a bimodal distribution of clavicle fractures, with the 2 peaks being men younger than 25
(sports injuries) and patients older than 55 years of age (falls).
• The middle third of the clavicle is fractured in 69% of cases following the distal third in 28% of
cases, and the proximal third in 3% of cases.
• Comprise up to 10% of all sport-related fractures and have the third-longest return time to
sport with as many as 20% of athletes with such injuries failing to return to sport.
• The clavicle is the only osseous link between the upper extremity and the trunk. Due to its
superficial subcutaneous location and the numerous ligamentous and muscular forces applied to it,
the clavicle is easily fractured. Because the midshaft of the clavicle is the thinnest segment and
does not contain ligamentous attachments, it is the most easily fractured location.
