Integrated Multidimensional Maturity Assessments Predicting the High-risk Occurrence of Peak Angle Velocity During Puberty in Progressive Female Idiopathic Scoliosis.
A consecutive and prospective longitudinal study. ⋯ Integrated multidimensional maturity assessments, defined as chronologic age between 11 and 13 years, modified Risser 0, DSA scores between 400 and 500, HV>6 cm/y, and SLV>20 mm/y, combined with preexisting scoliotic curve >30 degrees, were prone to increase the risk of entering the rapid curve acceleration phase in progressive IS girls.

Biomechanical Effects of a Dynamic Topping off Instrumentation in a Long Rigid Pedicle Screw Construct.
Biomechanical ex vivo study. ⋯ Introducing the dynamic topping off did not impart any significant difference in the segmental motion when compared with the rigid instrumentation. Therefore, the current biomechanical study could not show a benefit of using this specific topping off instrumentation to solve the problem of adjacent segment disease.
