Thoracolumbar Fascia Bursa

bursa fasciae thoracolumbalis

A bursa between the layers of the thoracolumbar fascia, particularly between the posterior and middle layers at the lateral raphe where they fuse lateral to the erector spinae. This potential space may accumulate fluid in inflammatory conditions affecting the posterior lumbar fascial system.

Region: Lower Back
Clinical Relevance

Clinical Notes

Thoracolumbar fascia bursitis contributes to lateral low back pain syndromes and is implicated in the 'fascia densification' seen in chronic non-specific low back pain. Ultrasound identifies fluid between fascial layers at the lateral raphe. Manual therapy targeting the thoracolumbar fascia and dry needling at the posterior-middle fascial junction address this component.
