1. Loss of the metatarsal arch is a common condition.
2. Its most frequent cause is high-heeled and short shoes.
3. Dorsal dislocation of the toes with plantar flexion is maintained by contraction of the plantar-flexor muscles.
4. The test for contraction is inability to dorsiflex the straightened toes with the fingers when the foot is held at right angles to the leg, by upward pressure on the ball of the foot.
5. Section of the plantar flexors relieves the flexion and dislocation, does not incapacitate the patient, and, when proper shoes are worn, gets rid of the corns and calluses.
6. The same treatment has corrected three cases of Morton's toe.
