A prospective multicenter study. ⋯ JOA, JOACMEQ, and VAS scores were not significantly different between those with, and without, loss of cervical lordosis. Preoperative small eROM and large OPLL may represent factors associated with loss of cervical lordosis after laminoplasty in patients with OPLL.

Quantifying the Contribution of Lower Limb Compensation to Upright Posture: What Happens if Adult Spinal Deformity Patients Do Not Compensate?
This is a multicenter, prospective cohort study. ⋯ Removal of lower limbs compensation revealed an unsustainable truncal malalignment with two-fold greater SVA.

Cross-sectional; observational. ⋯ NaF-PET/CT detects decreased vertebral bone turnover with aging, particularly in females. Measured NaF uptake increased with PET acquisition time after tracer injection, which must be considered in follow-up studies monitoring disease development and treatment effects.

Retrospective study. ⋯ Both NSAID and COX-2 inhibitor use in the early post-surgical period may be associated with increased rates of pseudarthrosis, hardware failure, and revision surgery in patients undergoing posterior spinal instrumentation and fusion.
