  • Morton’s Neuroma (Intermetatarsal Neuroma) A neuroma is a thickening of nerve tissue that may develop in various parts of the body. The most common neuroma in the foot is a Morton’s neuroma, which occurs between the third and fourth toes. It is sometimes referred to as an intermetatarsal neuroma.
  • Peripheral Arterial Disease (P.A.D.) Commonly referred to as “poor circulation,” Peripheral Arterial Disease (P.A.D.) is the restriction of blood flow in the arteries of the leg.
  • Talar Dome Lesion Talar dome lesions are usually caused by an injury, such as an ankle sprain. If the cartilage doesn’t heal properly following the injury, it softens and begins to break off. Sometimes a broken piece of the damaged cartilage and bone will “float” in the ankle.
  • 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.
  • 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.
  • 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.
  • Capsulitis of the Second Toe Ligaments surrounding the joint at the base of the second toe form a “capsule,” which helps the joint to function properly. Capsulitis is a condition in which these ligaments have become inflamed.
  • 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.
