326 MORBID ANATOMY.
1655-6. Paralytic calcaneo-valgus of both feet, in a girl get. eleven years, and the result of spina bifida ; the astragalus projecting on the inside of the foot, and making no part of the ankle-joint. The front of the foot was higher than the heel ; and the tendo-achillis was lengthened, instead of being shortened as usual. The three peronei muscles of the left foot, extens. longus comm., ext. poll, pedis, tib. ant. and tendo-achillis were divided ; and the same of the right, excepting the tib. ant. and tendo-achillis.
Four months after treatment the patient was able to walk upon the soles of the feet. 1869.
1657. Pes equinus in a lad, thirteen years of age, before treat- ment. Metatarsus doubled and twisted upon the tarsus, so as to form at the line of union a sharp and prominent ridge upon the top and side of the foot. Astragalus lux- ated, and very much diminished in size ; so that, in the course of treatment, it was almost impossible to keep it in place. Toes pressed backward so that the fifth was in contact with the back of the foot.
���1658. The same, after treatment. Shows the wrinkles in the skin where it was stretched over the astragalus and tarso- metatarsal prominences. Tendo-achillis cut four times ; tib. ant., flex, longus pollicis, and some fasciculi of the plantar fascia ; adductor pollicis twice ; also the ham- string muscles for a contraction of the leg upon the thigh. Dr. B. subsequently heard of the foot as still further im- proved. 1863.
