Enter the Cobb angle and the actual height into the calculator to estimate the height loss due to scoliosis. This calculator helps to approximate the impact of spinal curvature on a person's height.

Scoliosis Height Loss Formula

The formula used to estimate height loss due to scoliosis is based on the Cobb angle and the actual height of the individual.

HL = tan(CA) * AH

Variables:

  • HL is the estimated height loss (cm)
  • CA is the Cobb angle (degrees)
  • AH is the actual height of the individual (cm)

To estimate the height loss due to scoliosis, multiply the tangent of the Cobb angle by the actual height of the individual.

What is Scoliosis Height Loss?

Scoliosis height loss refers to the reduction in a person's height due to the curvature of the spine caused by scoliosis. The Cobb angle is a measure of the curvature's severity and is used to estimate the impact on height. Understanding the potential height loss can be important for medical assessments and treatment planning for individuals with scoliosis.

How to Calculate Scoliosis Height Loss?

The following steps outline how to estimate the Scoliosis Height Loss.


  1. First, determine the Cobb angle (CA) in degrees.
  2. Next, determine the actual height of the individual (AH) in centimeters.
  3. Next, gather the formula from above = HL = tan(CA) * AH.
  4. Finally, calculate the estimated Scoliosis Height Loss (HL) in centimeters.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Cobb angle (CA) = 25 degrees

Actual height (AH) = 170 cm
