Pott's Fracture.—In this the lower end of the fibula is broken and there is dislocation of the foot outward. The work is commenced, as in a bad sprain, by effleurage above the ankle, the injured part being gradually encroached on. Gentle flexion and extension of toes from the first, and of the foot after a few days, to keep the tendons moving and prevent matting ; the splint should not be removed for some days.

Colles' Fracture.—In this the lower end of the radius is broken, and there is flexion of the hand to the radial side. It is caused by falling on the extended hand. It is ' put up ' in anterior and posterior splints ; the latter only should be removed the first few days for massage. The fingers may be flexed and extended with extreme gentleness from the first, and after a few days slight movements of the wrist may be commenced.

When the anterior splint is removed, care must be taken in readjusting it that the first joints of the fingers come beyond the lower end. The work in all fractures and dislocations is quite simple, but it requires expertness, and should not be lightly undertaken by a novice.

The special point to be remembered in joint troubles, whether sprains, dislocations, or near by fractures, is that all muscles which move the joint, as well as being massed in the usual way, should be further acted on by exercise of the joints above and below the affected one as soon as it is safe to do so.

In the case of ruptured muscles the joints involved should not be exercised till repair has taken place, otherwise the tissues will be injured.
