Title
Outcomes in Adult Spinal Deformity Patients with Proximal Junctional Kyphosis or Failure
Hypothesis
Patients with proximal junctional kyphosis or failure will demonstrate distinct patterns in outcomes based on whether they are fused to the upper or lower thoracic spine.
Conclusion
Patients initially fused to the lower thoracic spine have a higher incidence of proximal junctional kyphosis and lower rates of improvement in disability, but a lower risk of neurological complications if reoperation is needed.
