  • Haglund’s Deformity Haglund’s deformity is a bony enlargement on the back of the heel. The soft tissue near the Achilles tendon becomes irritated when the bony enlargement rubs against shoes.
  • Hallux Rigidus Hallux rigidus is a disorder of the joint located at the base of the big toe. It causes pain and stiffness in the joint, and with time it gets increasingly harder to bend the toe.
  • Fractures of the Fifth Metatarsal Fractures (breaks) are common in the fifth metatarsal – the long bone on the outside of the foot that connects to the little toe. Two types of fractures that often occur in the fifth metatarsal are avulsion fractures and Jones fractures
  • Plantar Fibroma A plantar fibroma is a fibrous knot (nodule) in the arch of the foot. It is embedded within the plantar fascia, a band of tissue that extends from the heel to the toes on the bottom of the foot.
  • Accessory Navicular Syndrome People who have an accessory navicular often are unaware of the condition if it causes no problems. However, some people with this extra bone develop a painful condition known as accessory navicular syndrome when the bone and/or posterior tibial tendon are aggravated.
  • Equinus Equinus is a condition in which the upward bending motion of the ankle joint is limited. Someone with equinus lacks the flexibility to bring the top of the foot toward the front of the leg.
  • Deep Vein Thrombosis Deep vein thrombosis (DVT) is a condition in which a blood clot (a blockage) forms in a deep vein. While these clots most commonly occur in the veins of the leg (the calf or thigh), they can also develop in other parts of the body.
  • Chronic Ankle Instability Chronic ankle instability is a condition characterized by a recurring “giving way” of the outer (lateral) side of the ankle. This condition often develops after repeated ankle sprains.
  • Charcot Foot Charcot foot is a condition causing weakening of the bones in the foot that can occur in people who have significant nerve damage (neuropathy). The bones are weakened enough to fracture, and with continued walking the foot eventually changes shape.
  • Cavus Foot (High-Arched Foot) Cavus foot is a condition in which the foot has a very high arch. Because of this high arch, an excessive amount of weight is placed on the ball and heel of the foot when walking or standing.
