Quadratus Lumborum Involvement Diagnosis and Treatment

Diagnostic Considerations

  • X-rays of the spine may be indicated if there is suspicion of underlying bony pathology or to rule out vertebral fractures in appropriate clinical scenarios, as recommended by the World Journal of Emergency Surgery 1

Treatment Approach

  • Non-opioid analgesics are considered the first choice for pain management to avoid side effects like nausea and constipation, and Transversus abdominis plane (TAP) block or quadratus lumborum (QL) block can be considered for targeted pain relief, according to the World Journal of Emergency Surgery 2
