At what degree of spinal curve is surgery typically considered for scoliosis?

Surgery for scoliosis is typically considered when the spinal curve reaches about 40 degrees. At this degree of curvature, there is a significant risk that the condition will worsen as the individual continues to grow, and it can also lead to associated health issues, such as respiratory problems or reduced mobility, if left untreated.

The decision to proceed with surgical intervention is based on a combination of factors, including the degree of curvature, the age of the patient, and any potential complications associated with the curvature. A curve of 40 degrees is often viewed as a threshold where the potential benefits of surgery, such as correction of deformity and prevention of future complications, outweigh the risks involved in the surgical procedure.

Curvatures below this threshold may be monitored over time without immediate intervention, as they are less likely to cause significant functional impairments or health issues. Curves above 40 degrees are increasingly concerning and indicate a higher likelihood of progression, making surgery a more compelling consideration.
