Round shoulders and thieaccompanying so-called flat, but in reality narrow and thereforedeeper, chest may be induced also by obstructions in the respira-tory passages, such as enlarged tonsils, adenoids, and the like,or by bronchitis or heart disease. Another predisposing causeis clothing that prevents the full expansion of the chest and theextension of the arms, and even the weight of clothing suspended Fig. Posterior curvature of the spine in adolescence with rigidity.

These andother possible contributing causes should be investigated in allcases of this character. A more extreme type of deformity is sometimes seen in ado-lescents (Fig. 168), induced apparently by posture and byoverwork, although in most instances it may be assumed that aslighter deformity of long standing has served as a predisposingcause. In this type the deformity is resistant, and is accom- DEFOBMITIES OF THE SPINE. 227 panied by adaptive changes in the vertebrae that prevent com-plete correction.
