Overview

The hip joint and lumbar spine are biomechanically linked — dysfunction in one affects the other. Distinguishing hip-origin from spine-origin pain is crucial because their treatments differ significantly.

Possible Causes

Lumbar Radiculopathy

common

A compressed spinal nerve causes pain that radiates from the back into the hip and buttock.
