Clinical Trial
Selection of fusion levels in adolescent idiopathic scoliosis using fulcrum bending prediction: a prospective study.
A prospective study of 50 consecutive patients undergoing selective thoracic fusion for idiopathic scoliosis with minimum 2 year follow-up. ⋯ The new objective strategy for determining fusion levels using FB radiographs is safe and effective. With considering the flexibility of the curve, we are able to save levels distally in over 60% of patients. This strategy takes into account the power of modern instrumentation.

Comparative Study
Anterior spinal fusion versus posterior spinal fusion for moderate lumbar/thoracolumbar adolescent idiopathic scoliosis: a prospective study.
A prospective study. ⋯ ASF versus PSF comparison in treating moderate lumbar/thoracolumbar AIS did not show significant differences in regards to safety or efficacy but demonstrated shorter fusion levels, reduced surgical trauma and costs in ASF.

A retrospective study of postoperative pain management with intrathecal morphine. ⋯ Intrathecal morphine in the moderate dose range of 9 to 19 microg/kg (mean 14 microg/kg), provides safe and effective postoperative analgesia in the immediate postoperative period for patients with idiopathic scoliosis undergoing PSF and SSI. Higher doses did not result in significantly better analgesia and had a greater frequency of respiratory depression requiring PICU admission.

A radiographic study was conducted to investigate sacral morphology in a children and adolescent population with developmental L5-S1 spondylolisthesis. ⋯ The sagittal sacral morphology is a constant anatomic variable specific to each individual and unaffected by the position of the patient in space. The anatomy of the sacrum in children and adolescents with L5-S1 spondylolisthesis is particular and different from a control group. This study suggests that sacral anatomy may have a direct influence on the progression of spondylolisthesis; a lower STA and higher sacral kyphosis may be 2 factors predisposing to vertebral slip in developmental spondylolisthesis.

Multicenter Study Comparative Study
Age-gender matched comparison of SRS instrument scores between adult deformity and normal adults: are all SRS domains disease specific?
Prospective, observational study. ⋯ Our findings confirm the SRS instrument has excellent discriminate validity in the adult population. It appears to be disease-specific in the domains of pain, appearance and activity in adult spinal deformity patients who have not had prior surgery.
