CONCERNING THE ETIOLOGY AND TREATMENT OF CONGENITAL TALIPES CALCANEO-VALGUS
With Report of 23 Cases.
WALTER G. STERN M. D.
First. Besides the recognized changes in the form and position of the foot, one of the leading characteristics of congenital talipes calcaneo-valgus is the muscle unbalance consisting in passive contractures in the dorsal flexors and peronei muscles and overstretching, lengthening, relaxation and atrophy of the plantar flexors and supinators and tendo Achillis.
Second. These muscle changes are not dependent upon changes in the central nervous system but are due to forced position of the foot within the uterus in pronation, abduction and dorsal flexion.
Third. This forced position is due to an abnormal intrauterine pressure usually coming from a partial lack of liquor amnii.
Fourth. All cases should be treated as early as possible by means of overcorrection and fixation. This treatment is a cure for the muscle unbalance and usually restores the form of the foot.
Fifth. Both the type of the muscle unbalance and the results from such static treatment are additional proof of the pressure theory.
