A hand-book of surgery: with fifty illustrations . ectic. CLUB-FOOT. This deformity may be either congenital or acquired. The con-genital form is dependent upon some disturbance of the cerebro-spinal system, that produces irregular contraction of the muscles,by which antagonism is destroyed. The accidental causes by which it may be acquired, are injuriesand diseases of the foot or ankle, convulsions, scarlet fever, cica-trices, rickets, &c. The principal varieties are three :—1. Talipes Varus, in whichthe foot is turned inward, as in Fig. 45, and rests upon its outeredge. There are various grades and modifications of varus. Thefoot is not dislocated, but the bones deviate from their normal di-rection, and their articular surfaces are partially separated. Theastragalus is least altered in position. The ligaments on the outerside are lengthened, and those on the inner are shortened. The ton- 120 SURGERY. dons of the tibialis anticus and posticus, and the tendo Achillis, aremost contracted; the peronei muscles are relaxed. Fig. 2. Talipes Valgus. The foot is everted^ and rests on its inneredge. It is a rare form of club-foot. The ligaments on the innerside are relaxed. The peronei muscles are contracted^ and the tibi-alis anticus and posticus elongated. 3. Talipes Equinus.—In this variety the foot rests upon theball, or upon the toes. After a person has walked for a number ofyears the deformity is increased, as is represented in the drawing(Fig. 46). The shortening is due to contraction of the triceps ten-don^ and thickening of the plantar fascia. Fig. 46.
