In most cases, rib exostosis in adult women mainly affects the appearance and has no direct harmful effects on normal thoracic support and respiratory function. In a small number of severe cases, rib ectropion may affect thoracic expansion and cause some harm to respiration, such as faster breathing rate and shallow breathing depth, etc. Patients with this condition may have an effect on abdominal and diaphragmatic movements. Some patients may also have back pain, affecting normal bending activities. The cause of rib ectropion may be the sequelae of rickets due to calcium deficiency as a child, or it may be caused by congenital developmental deformities or traumatic fracture deformity healing. If it is not serious rib ectropion does not require special treatment, follow-up observation can be done, if it is a rib ectropion that affects breathing or seriously affects the appearance, surgical osteotomy orthopedic treatment can be considered.
