To validate the reliability of Berjano and Lamartina classification system of surgical planning in cases of de novo degenerative lumbar scoliosis (DNDLS) combined with degenerative segment disease and identify factors contributing to curve progression. ⋯ Selective decompression and short-segment fusion were effective for treating type I and II cases DNDLS. The Cobb angle increased relative to preoperative sagittal spine alignment. These slides can be retrieved under Electronic Supplementary Material.

There are still no data proving whether restoring the ideal sagittal profile (according to Roussouly classification) in adult scoliosis (AS) patients leads to any additional benefit, especially regarding mechanical complications. ⋯ Adult scoliosis surgery should restore the ideal Roussouly sagittal profile to decrease the rate of mechanical complications, especially in patients older than 65, instrumented to the pelvis.

To investigate the biomechanical effects of anterior column realignment (ACR) and pedicle subtraction osteotomy (PSO) on local lordosis correction, primary stability and rod strains. ⋯ Bilateral posterior fixation is highly recommended following ACR to provide adequate primary stability. However, primary rod strains in ACR were found comparable or higher than weak PSO construct associated with frequent rod failure; therefore, caution is recommended.

This study was aimed to identify correlation between maximum isometric strength in five muscle groups determined by dynamometry results of muscle tests and the inclination angles of the spine. ⋯ There is a strong association between isometric strength of the muscle groups of the hip extensors and erector spinae and the inclination angles of the spine. Based on the isometric results, physical therapy can be proposed for increasing the muscular strength of those muscle groups, which can help in the prevention of more severe forms of postural deformities.
