Many other operative procedures have been advised for flat foot and they have been employed with varying successes. +Hallux Flexus or Hammertoe.+ The upward prominence of a toe (usually the second or third) in a rigid position, is known as _hallux flexus_ or _hammertoe_. In this condition the toe is flexed in its second joint so that the end bears on the ground, while the junction between the phalanges makes a prominence upward. Helomata and callosities may develop on the end of the toe, but the chief discomfort is in the disturbances which arise on the prominence which presses against the side of the foot-gear. +Treatment.+ A knowledge of the forces at work will show how futile must be any effort to correct this deformity by strapping or bandaging. There is a shortening of the plantar fibres of the lateral ligament of the joint. The trouble does not lie in the flexor tendons, as it seems, and operations directed to this point fail. Even with incision of the lateral ligaments, followed by the application of a splint, recurrences are common and amputation must be the procedure. The condition described as hammertoe may exist in several or in all of the toes, the great toe being least often involved. This occurs most often as a result of wearing improper shoes, but is sometimes the consequence of paralysis. +Flexed or Clawed Toes.+ Extreme flexion of all but the great toes causes the weight to be borne by their dorsal aspect. In this condition the toes, and especially the small ones, develop painful helomata on the prominent joints, and the small toe may become the source of great discomfort. +Treatment.+ Radical surgical measures are here indicated. Tenotomy or amputation is essential to a cure. +Painful Heel.+ Painful heel is a suggestive but unscientific term applied to tenderness of the under side of the heel. It is associated with one of the following conditions: 1. Spurs running out from the under side of the os calcis found by the aid of the X-ray. 2. Inflammation of the bursae under the os calcis. 3. Flat foot. 4. Gonorrhœa. 5. Focal infection. +Treatment.+ Where a spur of bone causes the unpleasant symptoms, the excrescence should be excised. When focal infections are the primary cause of painful heel, operative procedure to remove the source of infection is imperative and will prove curative. Palliative measures are: massage, douches, hot air, a metal plate worn under the painful area, rest. The back of the foot should be cut away to relieve pressure. +Metatarsalgia—Morton’s Disease.+ Metatarsalgia is characterized by an acute pain, cramplike in character, occurring at the base of the third or fourth toes. The pain comes on suddenly while the foot is in action, and is usually accompanied by a “snapping of the bones.” The pain is so acute that it is not uncommon for the patient to seek relief by taking off the shoe and rubbing the foot.
