Whereas the costs of primary surgery, revisions, and selected complications for adult spinal deformity (ASD) have been individually reported in the literature, the total costs over several years after surgery have not been assessed. The determinants of such costs are also not well understood in the literature. ⋯ The incidence of readmissions increased the average cost of ASD surgery by more than 70%, illustrating the financial burden of revisions/reoperations; however, the cost burden resulting from readmissions appeared to taper off within 5 years after surgery. The estimated impact of physician preference on OR costs also highlights the variation in current practice and the opportunity for large cost reductions via a more standardized approach in the use of implants and biologics.

Comparative Study Observational Study
Depressive burden is associated with a poorer surgical outcome among lumbar spinal stenosis patients: a 5-year follow-up study.
In lumbar spinal stenosis (LSS), conservative treatment is usually the first choice of treatment. If conservative treatment fails, surgery is indicated. Psychological factors such as depression and anxiety are known to affect the outcome of surgery. Previous studies on depression and surgery outcome using long follow-up times are scarce. ⋯ Even slightly elevated long-term depressive symptoms in LSS patients are associated with an increased risk of a poorer functional ability after decompressive surgery.

Adolescent idiopathic scoliosis (AIS) is a complex three-dimensional (3D) deformity of the spine involving deviations in the frontal plane, modifications of the sagittal profile, and rotations in the transverse plane. Although Lenke classification system is based on 2D radiographs and includes sagittal thoracic and coronal lumbar modifiers, Lenke et al. suggested inclusion of axial thoracic and lumbar modifiers in the analysis. ⋯ Addition of axial plane analysis to conventional coronal and sagittal evaluations in patients with Lenke 1A curves may reveal inherent structural differences that are not apparent in single planar radiographic assessments and may necessitate a different surgical strategy.

Percutaneous kyphoplasty is effective for pain reduction and vertebral height restoration in patients with osteoporotic vertebral fractures. However, in cases of severely collapsed fractures involving the loss of more than 70% of the vertebral height, kyphoplasty is technically difficult to perform and the outcomes remain unknown. ⋯ In patients with an anterior vertebral compression ratio more than 70% because of osteoporotic vertebral fracture, although the anterior height and kyphotic angle were significantly lower than those of patients with an anterior vertebral compression ratio of 30% to 50%, kyphoplasty significantly improved the degree of pain, restored the anterior vertebral height, and maintained the kyphotic angle. Therefore, kyphoplasty can be a useful approach in patients with an anterior vertebral compression ratio more than 70%.

The incidence and relevant risk of ischemic stroke after cervical spine trauma remain unknown. ⋯ This analysis revealed that ischemic stroke after cervical spine injury was not uncommon and was associated with increased mortality and morbidity. Occurrence of ischemic stroke was significantly associated with age, comorbidities such as diabetes, and consciousness level at admission, but not with the type of spine injury.
