Treatment of lesions between the =manubrium= and =gladiolus= are best given by placing the patient with the face downward upon the operating table, and having the articulation of the manubrium and gladiolus just over the edge of the table. An assistant should hold the patient firmly upon the table while hyperextension or flexion, as the case may require, with traction, is exerted upon the head, neck and shoulders, and manipulation of the articular points is given to reduce the dislocation. The same principles are employed here as in correcting lesions elsewhere. Correction of the =cartilages along the sternum= is very easily accomplished by having the patient sit upon a stool and the osteopath standing behind the patient places a knee in the back; then reaching around with one hand over the cartilages and the other hand underneath the axilla, execute the same movement as given in correcting dislocations of the sternal ends of the ribs. A treatment sometimes used to release a depressed condition of the =cartilages= of the =false ribs= is to stand behind the patient while he sits upon a stool and reach around him with fingers underneath the cartilages and raise them upward as he inhales. By having the patient take a deep breath and then exhale quickly while the fingers are over the cartilages a much better grasp of them can be obtained. This treatment should be carefully given, as there is danger of tearing the cartilages loose from the ribs. =The Dorsal and Lumbar Spinal Regions.=—Here, as in other regions of the body, before an attempt is made to correct the vertebræ the muscles should be thoroughly relaxed. One of the easiest methods to relax the muscles is to have the patient lie upon the side, and then by standing in front of the patient and reaching over him with the fingers upon the contracted muscles an upward and outward rotary manipulation is given; or the patient may sit upon a stool while the physician stands in front with the arms around the patient and the fingers over the contracted muscles manipulating them upward and outward. Another very easy method is to stand behind the patient while he sits upon a stool and place a thumb over the contracted fibres, with the other hand underneath the axilla lifting the shoulder upward and backward so as to favor a relaxation of the muscles, while the thumb manipulates them.
