A retrospective review of a prospective adult spinal deformity data. ⋯ LPA enabled the delineation of three distinct phenotypes among ASD patients, each characterized by unique clinical profiles and distinct long-term recovery trajectories. By pinpointing the crucial variables that uniquely distinguish and predict membership in different phenotypes, the study provides valuable guidance for patient stratification.

Biomechanical study by using a multi-body simulation approach. ⋯ L1/2 fusion in a tethered spine reduces tether forces in adjacent segments and thus might decrease the rate of tether breakage. However, fusion results in increased intervertebral compression forces by up to 31% compared to an unfused spine. Long-term clinical studies are needed to further analyze and evaluate the biomechanical consequences.

Retrospective Cohort Study. ⋯ T&T optimizes screw accuracy while reducing the increased radiation burden and operative time associated with CAS. The T&T approach incorporates CT-based navigation technology as confirmation, while maintaining surgeon's skill.
