[Lung topography and function in thoracic deformity]

In kyphoscoliosis, a rotation of the convex-sided lung around a vertical axis, can be observed. In comparison of "pure" scoliotics with kyphoscoliotics, the degree of kyphosis seems to counteract the rotating effect of scoliosis. This effect is possibly related to the duration of the deformity, insofar as, rotation increases primarily due to scoliosis and then tends to disappear with age-related development of accompanying kyphosis. The clinical relevancy and the kyphosis-dependent changes lf lung function, are discussed.
