This is a condition in which the legs are bent inward so that the knees interfere with each other in walking. It occurs in consequence of weakness of the ligaments or muscles about the knee. It sometimes occurs in consequence of strains. In some cases of children it becomes so bad that the patient cannot walk without crutches. Children suffering with this difficulty are generally poorly nourished, and hence supplying hygienic conditions is one of the most important elements of treatment. It is generally necessary, in addition, to support the weak limb by means of a splint placed at the back of the joint and over the outer side of the limb. The bandage should be applied in such a way as to correct the deformity as much as possible, the limb being by degrees restored to its natural condition. Very bad cases require specially constructed apparatus, such as is shown in Fig. 441.

Short-Leg - Deformities Of The Hands And Feet

This may be a natural or an acquired deformity. When the degree of shortness is not very great, the difficulty of walking may be relieved to a very considerable extent, and distortion of the body prevented, by an addition to the sole of the shoe worn upon the foot of the shorter limb, as shown in Fig. 442. In cases in which there is a great degree of shortening, an instrument similar to that in Fig 443 is sometimes required.
