Protect Your Joints

The ankle joint is one of the major weight bearing structures in the body. Since it is so important to our movement, ankle sprains, strains and fractures have been very common. Any of these injuries can be caused by many different things such as falling, running, sudden impact, rolling or landing on it wrongly. Treating initial ankle injuries or issues can help prevent ongoing ankle problems. Injury in these areas can compromise your range of motions such as walking, running and jumping.

Understanding The Ankle

The ankle is surrounded by muscles, ligaments and other tissues to support the weight of the body during movements such as walking, running and jumping. Most of the muscles that stabilize and move the ankle are located in the lower leg and attach to the foot. The three bones are held together at the ankle joint by ligaments that allow normal ankle movement.

Major bones of the ankle:

  • Fibula
  • Tibia
  • Talus

Major muscles and functions of the ankle:

  • Dorsiflexion: tibialis anterior, extensor hallucis longus and extensor digitorum longus
  • Plantarflexion: gastrocnemius, soleus, posterior tibialis, fibularis longus and brevis
  • Inversion: posterior tibialis
  • Eversion: fibularis longus and brevis
