Episode Title: Why 10 Degrees Is the Diagnostic Threshold for Scoliosis
Why is scoliosis officially diagnosed at 10 degrees? In this episode, Dr. Tony Nalda explores the origin of the 10-degree cutoff, what it means for patients, and why the numbers don’t always reflect the impact scoliosis can have on daily life.
✅ What Is Scoliosis?
A lateral curvature of the spine of 10 degrees or more, with spinal rotation
Must be measured via Cobb angle on a standing spinal X-ray
Three-dimensional deformity—not just a sideways curve
✅ Cobb Angle & Severity Categories:
Mild: 10–25 degrees
Moderate: 25–40 degrees
Severe: 40+ degrees
Very Severe (Dr. Nalda’s category): 80+ degrees
These classifications were originally designed by orthopedic surgeons for surgical decision-making, not necessarily for predicting symptoms or patient outcomes.
✅ Why 10 Degrees?
In 1977, Dr. William Kane proposed 10° as the cutoff to create diagnostic consistency
Prior to this, some doctors diagnosed scoliosis at 5°, 15°, or even 20°
The 10-degree benchmark became the accepted clinical standard—but not because it signified a dramatic physiological shift
✅ Why "Mild" Scoliosis Can Still Be Serious:
Even small curves (10–20 degrees) can cause pain, dysfunction, and postural changes
Many patients with 15–20 degree curves experience symptoms despite being labeled “mild”
Early misalignments are like car tires out of alignment—they wear things down over time
✅ The Problem With Chasing Numbers:
Curves less than 10° are still spinal misalignments
Scoliosis isn’t always visible until 20–25°, meaning millions go undiagnosed
Many people don’t realize they have scoliosis until adulthood, especially if pain is minimal in youth
✅ What Matters Most:
Not just the degree of curvature, but the impact on your health and function
Early detection and proactive, conservative treatment can prevent small curves from becoming severe
Look beyond the labels—what matters is how your spine is affecting your quality of life
Every severe scoliosis case started out as a smaller curve. The earlier you intervene—regardless of whether it's “mild” or not—the better your chances are to prevent long-term progression.
