This is an improvement upon the male andfemale screw, and the double-acting ratchet-screws often used for the purpose. Thesimple arrangement of a movable thumb-screw has, in addition to lightness, theadvantage of permitting mobility of the ankle in the direction of bending—a circum-staiice of much importance. No other apparatus which the author has seen possessesthe advantages of permitting perfect freedom of motion of the ankle during exercise oras much freedom as the suigeon may consider desirable, and, owing to the action of Fig. 19.—Dr. Littles Shoe for Varus of the left a, strap to be attached to tlie buckle h, iuteuiled to moderate the action of the lever-spring c ; d, two straps which startfrom within the heel-piece on the outer side of the foot near the sole-piece, and are intended to be secured to buckleson the opposite side of the instrument, for the pm-pose of holding the posterior part of the foot firmly against theinside of the shoe, whilst the strap e, and short spring to which it is attached, draw the front of the foot convalescent may take exercise in this apparatus. the spring lever, continually disposing the patient to tread on the inner margin of thesole. Cases of the first grade of infantile deformity are usually rectified in two orthree weeks, those of the second grade in about four weeks, and those of the highestgrade, the operation and the mechanical treatment having been divided into two orthree stages, within two or three months.
