The quadratus lumborum is a deep muscle located in the posterior abdominal wall, extending from the iliac crest to the 12th rib and lumbar vertebrae. It stabilizes the spine, assists in lateral flexion of the trunk, and plays a role in breathing by anchoring the diaphragm. Dysfunction or tightness can lead to lower back pain, hip imbalance, and restricted movement. Physical therapy often targets this muscle through stretching and strengthening exercises. Its anatomical location near the kidneys, abdominal vessels, and lumbar plexus also makes it significant in regional anesthesia and abdominal or spinal surgery, where careful dissection ensures safety and preserves function.
