In the first are placed the instruments which simply retain the foot in position; in the second, those which likewise extend and exercise the limb. The simplest form of appliance for retention of the foot in infantile cases, is a padded splint, which is shaped to the tibial surface of the leg, and rendered rectangular at the shoepart. When applied, it is bound on the leg by a few folds of an elastic roller. This splint can be worn by night as well as by day, as it is perforated, in order that the limb may be kept cool by the free admission of air. The next retentive instrument for varus is composed of a metallic stem, passing as high Fig. 31. as the centre of the calf, on the tibial or inner surface of the leg. This stem is attached below to a stiffened laced-boot, and is furnished at the ankle with a stop-joint, i.e., one that is limited in action to flexion of the foot upon the leg, by a metallic point, or spur. This is intended to prevent re-contraction of the tendoAchillis, which might take place if a too ready extension were permitted. The outer ankle is supported by a triangular strap, which preserves the foot in its corrected posture, by acting against the metallic stem. Another appliance consists of two lateral stems, fixed to a calf-band, and furnished with Fig. 32. stop-ankle-joints; the object of which is to maintain the plantar surface of the foot in a horizontal position, especially where it manifests any tendency to obliquity. Since the two stems are fixed to a calf-band, they compel the bottom of the foot to remain at right angles with themselves; for it would be impossible for the sole to become oblique, without lessening the length of one of the perpendicular bars-...
