Information for Patients

Ankle Injuries and Disorders

Your ankle bone and the ends of your two lower leg bones make up the ankle joint. Your ligaments, which connect bones to one another, stabilize and support it. Your muscles and tendons move it.

The most common ankle problems are sprains and fractures. A sprain is an injury to the ligaments. It may take a few weeks to many months to heal completely. A fracture is a break in a bone. You can also injure other parts of the ankle such as tendons, which join muscles to bone, and cartilage, which cushions your joints. Ankle sprains and fractures are common sports injuries.

  • Ankle arthroscopy
  • Ankle fracture - aftercare
  • Ankle pain
  • Ankle replacement
  • Ankle sprain - aftercare
  • Foot, leg, and ankle swelling

Foot Injuries and Disorders

Each of your feet has 26 bones, 33 joints, and more than 100 tendons, muscles, and ligaments. No wonder a lot of things can go wrong. Here are a few common problems:

  • Bunions - hard, painful bumps on the big toe joint
  • Corns and calluses - thickened skin from friction or pressure
  • Plantar warts - warts on the soles of your feet
  • Fallen arches - also called flat feet

Ill-fitting shoes often cause these problems. Aging and being overweight also increase your chances of having foot problems.

  • Claw foot
  • Clubfoot
  • Common peroneal nerve dysfunction
  • Extremity x-ray
  • Flat feet
  • Foot pain
  • Foot sprain - aftercare

Toe Injuries and Disorders

Fourteen of the 26 bones in your feet are in your toes. The toes, particularly your big toe, help you move and keep your balance. Playing sports, running, stubbing your toe, and dropping something on your foot can damage your toes. Wearing shoes that are too loose or too tight can also cause toe problems. Certain diseases, such as severe arthritis, can cause toe problems and pain. Gout often causes pain in the big toe.

Common toe problems include

  • Corns and bunions
  • Ingrown toenails
  • Sprains and dislocations
  • Fractures

Treatments for toe injuries and disorders vary. They might include shoe inserts or special shoes, padding, taping, medicines, rest, and in severe cases, surgery.

  • Broken toe - self care
  • Bunion removal
  • Bunions
  • Clubbing of the fingers or toes
  • Hammer toe
  • Hammer toe repair
  • Hammer toe repair - discharge
  • Polydactyly
