Avoiding Pitfalls in Adult Spinal Deformity.

To avoid the high rate of complications associated with the surgical management of adult spinal deformity, it is important to recognize and avoid three major pitfalls. The first is patient selection and determining which cases are appropriately indicated. The second is optimizing modifiable medical issues that can lead to a poor outcome, such as smoking, vitamin D deficiency, nutritional status, and poor bone quality. The third is optimizing surgical factors such as defining clinically appropriate, patient-specific target alignment goals as well as using techniques to avoid proximal junctional kyphosis and proximal junctional failure. It is important to describe these three key pitfalls that are commonly seen in the treatment of patients with adult spinal deformity and to describe methods to avoid them.
