Anatomy of the Clavicle (Collarbone)

Anatomy

• The clavicle, also known as the collarbone, is a long, slender bone located between the shoulder blade (scapula) and the breastbone (sternum).
• It is a paired bone, with one clavicle on each side of the body.

Function

• The clavicle serves as a connection between the arm and the body, providing a point of attachment for muscles and ligaments.
• It helps to support the shoulder and allows for a wide range of motion.

Structure

• The clavicle is curved, with an S-shaped appearance.
• It has two ends: the sternal end (which articulates with the sternum) and the acromial end (which articulates with the scapula).
• The clavicle is composed of compact and cancellous bone tissue.

Development

• The clavicle is the first long bone to ossify (harden) during fetal development, beginning around 5-6 weeks.
• It is also one of the last bones to fully ossify, which occurs around 21-25 years of age.

Clinical Significance

• Fractures of the clavicle are common, particularly in children and young adults.
• The clavicle is also susceptible to osteolysis, a condition characterized by the destruction of bone tissue.
• In some cases, the clavicle may be surgically removed or repaired to treat certain conditions or injuries.
