It often looks as if pressure, as by the hands, had beenapplied to the sides of the chest about the anterior axillary line, causingthe anterolateral portion to sink inward and the anteromedian portionto project forward. The chest of rhachitis is attended by enlargement of the osteocartilagi-nous articulations of the ribs called the rhachitic rosary. The rhachitic chest must not be confounded with chests exhibitingsimilar changes in shape due to abnormal conditions of the upper re-spiratory apparatus in early childhood. In cases of adenoid disease ofthe pharynx (see Diseases of the Pharynx) the change in shape of thechest has been noted. The rhachitic shape of the chest does not indicate any disease of thelungs, but does indicate deficient respiratory capacity, and is the tell-talesign by which rhachitis of early life or early laryngeal and nasal obstruc-tion is recognized.

It is caused in early life by thepressure of the external columns of air on the soft bony thorax whoselungs are not completely filled with air. Hence, it indicates the oc-currence in early life of nasal, faucial, or bronchial obstruction fromadenoid disease, from bronchial catarrh, or from other causes. It maymark the upper limit in infancy of the liver on the right side. Deformities must not be confounded with the rhachitic chest. Cer-tain deformities of the chest may be congenital in origin and other de-formities may be the result of occupation (shoemaking), or of vertebral
