Two cases of low back pain from quadratus lumborum myofascial trigger points are presented. One of the patients suffered from an acute episode while the other had a chronic condition. This condition may be more common than previously believed. ⋯ Thoracolumbar joint dysfunction may often coexist with quadratus lumborum myofascitis and must be treated for optimal results. Myofascial therapy directed at restoring muscle length and function, coupled with joint manipulation to related dysfunctional areas, was implemented. Diagnosis and treatment are outlined.
