Scheuermann’s Disease (Kyphosis)

Scheuermann’s Disease (Kyphosis)

Scheuermann’s disease is a spinal condition that causes an excessive forward curve of the upper back, giving it a hunched appearance. It typically affects children and teenagers while they are still growing and is a specific type of kyphosis. The condition is named after Danish orthopedic surgeon Holger Scheuermann and is often manageable with early treatment.

Causes

The exact cause is unknown, but it’s believed to involve abnormal bone growth during development. It may be linked to reduced blood supply to the vertebrae or inherited traits. Some genetic disorders like Marfan Syndrome or Ehlers-Danlos Syndrome can increase risk. It affects boys more than girls, typically at a 2:1 ratio.

Symptoms

Common symptoms include:

• Noticeable hunching or forward curve in the upper back
• Back pain, especially after sitting or physical activity
• Muscle tightness or spasms
• Reduced flexibility or motion
• Rarely, breathing or digestion issues due to severe curvature

Pain is reported in about half of diagnosed cases. When the curve occurs in the lower back (lumbar spine), pain may be more pronounced.

Diagnosis

Diagnosis usually happens after age 10 and involves:

• Physical exam: checking posture and spine flexibility
• X-rays: identifying wedge-shaped vertebrae and curve severity
• MRI or CT scans: used if other spinal issues are suspected, like tumors or infections

A diagnosis is often made when three or more vertebrae are wedge-shaped (by 5 degrees or more) and the overall curve is 45 degrees or greater.

Treatment Options

Early detection allows for less invasive treatment. Options include:

• Physical therapy: Helps strengthen spinal muscles and improve flexibility, especially effective while the spine is still growing.
• Low-impact exercise: Activities like swimming and biking are encouraged, while avoiding strenuous sports.
• Bracing: Wearing a custom brace for 12–24 months can help correct posture during growth. Types include the Milwaukee, Kyphologic, and Boston braces.
• Surgery: Reserved for severe cases (curves over 75 degrees) that cause major pain or deformity. Typically not the first choice for growing children.

Importance of Early Detection

The sooner Scheuermann’s disease is identified, the better the outcome. Most children respond well to non-surgical treatments, and symptoms often improve once spinal growth is complete.
