The femur is the body's strongest bone, so it usually breaks from major force like a car crash.

Blood loss into the thigh can be large.

• Bruising

When to get medical care

Causes

Trauma.

Who is more likely to get it

• Older adults with weak bones: Higher risk
• Young people in car crashes: The most common cause

Possible complications

• Blood clot in the leg (DVT): Common after leg fractures
• Fat embolism: Rare, fat travels to the lungs

Treatment

Which doctor treats this

• Emergency doctors treat it first, in the ER.
• They may send you to an orthopedist (bone and joint doctor).
• A physical therapist can help with exercises to rebuild strength and motion.

Back to school, work, or sports

• School or desk work is often OK within days. Jobs with lifting may need light duty for a while.
• Go back to sports only when your doctor says it's OK and you have full motion and strength without pain.

Children, pregnancy, and older adults

• Older adults: Hip-area breaks are more common.

For caregivers

• Go to visits when you can and take notes.
• Keep a list of medicines, allergies, and doctors in one place.
• Learn the warning signs that need fast care.
• Take breaks and ask for help. Caregivers need care too.
