The clavicle, or collarbone, is one of the most frequently fractured bones in bicycle accidents due to its anatomical position and the mechanics of cycling falls. When a cyclist is thrown from their bike or collides with a vehicle, the impact force travels through the outstretched arm and concentrates at the collarbone, which acts as a structural strut between the torso and shoulder. This bone is particularly vulnerable because it is relatively thin and lacks the muscular protection that surrounds other bones in the body.
Collarbone fractures are classified into three types based on their location: middle-third fractures (the most common, accounting for about 80% of cases), distal-third fractures (occurring near the shoulder), and proximal-third fractures (near the sternum). The severity can range from hairline cracks to complete breaks where the bone fragments are displaced or even pierce through the skin in compound fractures. Symptoms include immediate sharp pain, visible deformity or bump at the fracture site, inability to lift the arm, swelling, bruising, and a grinding sensation when attempting to move the shoulder.
Medical diagnosis typically involves physical examination followed by X-rays to confirm the fracture and assess its severity. In complex cases, CT scans may be ordered to evaluate bone fragment positioning and plan surgical intervention. Treatment depends on the fracture type: simple fractures may heal with immobilization using a figure-eight brace or arm sling for 6-12 weeks, while displaced or comminuted fractures often require open reduction and internal fixation (ORIF) surgery. Recovery can take 3-6 months, with physical therapy essential for regaining strength and range of motion. If you've suffered a bicycle accident resulting in a collarbone fracture, seeking immediate medical attention and legal counsel is crucial for protecting both your health and your rights.
