  • Tarsal Coalition A tarsal coalition is an abnormal connection that develops between two bones in the back of the foot (the tarsal bones).
  • Fractures of the Calcaneus (Heel Bone Fractures) Most calcaneal fractures are the result of a traumatic event—most commonly, falling from a height, such as a ladder, or being in an automobile accident where the heel is crushed against the floorboard.
  • Gout Gout is a disorder that results from the build-up of uric acid in the tissues or a joint. It most often affects the joint of the big toe.
  • Lisfranc Injuries Injuries to the Lisfranc joint most commonly occur in automobile accident victims, military personnel, runners, horseback riders, football players and participants of other contact sports, or something as simple as missing a step on a staircase.
  • 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.
  • Os Trigonum Syndrome The os trigonum is an extra (accessory) bone that sometimes develops behind the ankle bone (talus). It is connected to the talus by a fibrous band. The presence of an os trigonum in one or both feet is congenital (present at birth).
  • 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.
