Low back pain is one of the most common reasons people seek chiropractic care. While factors like posture, activity levels, and injuries are well-known contributors, there’s growing interest in understanding whether genetics play a role. According to spine biomechanics expert Stuart McGill, PhD, the shape of your vertebral bodies and discs can predispose you to specific mechanisms of low back pain. Let’s explore how these anatomical differences might be inherited and how they influence susceptibility to back pain.

The Anatomy of the Spine and Genetic Influence

The human spine is made up of vertebrae and intervertebral discs, which vary in shape and size among individuals. These differences are often determined by genetics and can influence how your spine responds to different types of stress. Some people have vertebrae and discs that make them more resilient to certain movements, while others may be predisposed to injuries from specific forces.

McGill’s research highlights that vertebral shape significantly impacts spinal biomechanics. For instance, individuals with rounder-shaped vertebral bodies and “plump” discs are typically more resistant to rotational forces but may be more vulnerable to compressive loads. Conversely, those with kidney bean-shaped vertebral bodies and thinner, wider discs are better equipped to handle compressive forces but are more susceptible to rotational stress.

Gymnasts and Compression Injuries

Consider the example of gymnasts. Due to their genetic predisposition, many gymnasts tend to have rounder vertebral bodies and plump, hydrated discs. This spinal configuration allows them to handle significant rotational movements, such as twists and flips, without much wear and tear. However, the same anatomy makes them vulnerable to injuries from compressive forces, such as heavy weightlifting or prolonged axial loading.

When a gymnast’s spine is subjected to excessive compression—think landing hard from a vault or performing repeated spine-loading exercises—the risk of low back pain increases. Chiropractic care tailored to decompress the spine and improve joint mobility can be crucial for managing these issues.

Rotational Stress in Individuals with Kidney Bean-Shaped Vertebrae

On the other hand, people with kidney bean-shaped vertebral bodies and wider, thinner discs are built to withstand compressive forces more effectively. These individuals may excel in activities requiring heavy lifting or prolonged sitting under load. However, their anatomy makes them more vulnerable to rotational forces, which can lead to injuries like disc herniations or joint irritation.

For example, a golfer who repeatedly twists their spine during swings may experience low back pain if their vertebral shape predisposes them to rotation-related injuries. Chiropractic adjustments and exercises focusing on core stability and rotational control can be highly effective in preventing and managing such pain.
