Rib deformity in scoliosis [PDF]

open access: yesEuropean Spine Journal, 2003
Rib deformity in scoliosis is of interest because it may help in the diagnosis, and also, in some pronounced cases, it may need correction by costoplasty. There are, however, debates about its use in diagnosis, because some authors think that rib deformity is not closely related to either the magnitude or the extent of rotation of the curve.
