Short Leg Associated with Lumbar Disk Herniation

A new study investigated the role of leg length discrepancy and the occurrence of lumbar disk herniation. It has long been theorized that inequality in leg length may lead to abnormal transmission of load across the vertebral endplates and degeneration lumbar spine and the disk space. The study included 39 subjects with leg length discrepancy and low back pain as well as 43 people with just low back pain. Investigators found a statistically significant association between leg length inequality and the occurrences of lumbar disk herniation. Further research is needed, but the findings suggest that addressing leg length inequality may reduce an individual’s risk of lumbar disk herniation.
