Severe rigid scoliosis: Evaluating the role of anterior release and its impact on pulmonary function.

Severe rigid scoliosis (>90° Cobb angle; <30 % flexibility) presents major challenges in deformity correction and pulmonary preservation. This narrative review outlines current surgical strategies, with a focus on anterior spinal release and its biomechanical and respiratory implications. Disc-rib-head excision improves axial rotation and sagittal alignment, reducing the need for extensive posterior osteotomies and high implant density.

Selection of Lowest Instrumented Vertebra in Lenke 5 and 6 Adolescent Idiopathic Scoliosis: A Network Meta-analysis of Existing Evidence.

Study Design: Network meta-analysis.

Objectives: To determine lowest instrumented vertebra (LIV) in Lenke 5 & 6 Adolescent Idiopathic Scoliosis (AIS) patients.

Methods: An extensive literature search was carried out aimed at identifying articles reporting outcomes in Lenke 5 and 6 AIS patients based on LIV selection.
