=Lateral curvature= in the dorsal region is undoubtedly the hardest to correct on account of the ribs, which complicate the condition. A marked curve in the dorsal region is sure to be accompanied by a dislocation of the vertebral end of one or more ribs. Treat each distinct lesion separately, follow by general stretching, replacing and molding of the tissues. A good method to stretch tissues and adjust a moderate lateral curve is to utilize the swing, or in lieu of this have the patient stand just at arm’s length from the wall with concave side toward the wall with straight arm at right angles and palm resting against the wall. Stand in front of patient whose feet are firmly on the floor and reach around with both hands upon the spine. As the patient sidebends toward the wall it tends to correct the deformity, so if the operator coordinates his adjustment with that lateral movement of the patient, precise fulcra can be obtained and a certain, definite correction secured. The significance rests with the stretching of tissues and the definite fulcra obtained, thereby securing a maximum sidebending and rotation toward correction. The =dislocation= of an =innominate= sometimes complicates matters, but is a simple point to remedy, and should not be overlooked. The correction of a curvature presents a special study to the osteopath, whether it be scoliosis, kyphosis or lordosis, and special rules cannot be laid down for treatment. Cases of rare occurrence are what might be termed “symmetrical” curves; i. e., no vertebra presents separately a marked lesion, the column on the whole being simply bowed. Such cases can be treated by springing back the spinal column, and by the use of methodical exercises. Unfortunately most curvatures are characterized by various lesions between the vertebræ, and thus each lesion requires special work. In simple curves the use of braces, jackets, and the various mechanical appliances are of very little use to the osteopath, in fact, more harmful on the whole, than beneficial. Naturally they would apply to a “symmetrical” curve, or where the patient is too weak to sit or walk, but they can be of very little use to the average patient, in place of correct osteopathic treatment. Mechanical appliances confine the movements of the patient, interfere with the development of the muscles, and impinge to a greater or less extent the spinal nerves. Due attention to hygienic surroundings and diet are certainly of aid. Proper exercises and occupation for the sufferer should be advised. Special care should be taken in examining (radiographic) for infectious lesions (arthritis).
