Lumbar Lordosis Angle: How to perform

Last updated on July 6 2022

 

Description

Lumbar Lordosis is an important postural component and it is a parameter to characterize the Sagittal Balance. It can be used in assessing postural abnormalities. There is evidence that many factors, such as age, gender, body mass index, ethnicity, and sport, may affect the lordosis angle, making it difficult to determine uniform normal values. Normal lordosis should be determined based on the specific characteristics of each individual. To calculate the Lumbar Lordosis, it is required a lateral view.

This procedure measures the lumbar lordosis angle (LLA) which is the angle formed between the superior end plate of L1 and the superior end plate of S1 and should be lower than pelvic incidence (Normal is LLA = pelvic incidence + 10°).
