Improved pulmonary function after concave rib resection and posterior instrumentation for idiopathic scoliosis.

The authors conducted a prospective study in order to evaluate the effect'of concave rib osteotomy on pulmonary function, in the context of posterior instrumentation for the treatment of idiopathic scoliosis. Concave rib osteotomy improves the flexibility of the spine, especially in very rigid curves above 70. Seventy-eight consecutive children with a Cobb angle above 70 degrees were included in the study.

Concave rib osteotomy: a modified technique revisited.

This is a prospective study reporting on the efficacy of a modified technique of Concave Rib Osteotomy (CRO) in conjunction with posterior instrumented fusion in the treatment of severe and rigid curves in patients with adolescent idiopathic scoliosis. The mean post-operative frontal plane correction was 68%. The incidence of pulmonary complications was 11.
