Don’t obtain spinal imaging for patients with acute low-back pain during the six weeks after onset in the absence of red flags.
|Rationale and Comments:||In the absence of red flags, evidence-based guidelines do not support the routine use of spinal imaging for patients with acute back pain of less than six weeks duration. Red flags include history of cancer, fracture or suspected fracture based on clinical history, progressive neurologic symptoms, and infection, as well as conditions that potentially preclude a dynamic thrust to the spine, such as osteopenia, osteoporosis, axial spondyloarthritis, and tumors. Unnecessary imaging incurs monetary cost, exposes the patient to ionizing radiation, and can result in labeling patients with conditions that are not clinically meaningful, creating a false sense of vulnerability and disability. Indeed, several studies have shown that the routine use of radiographs in the care of low-back pain may result in worse outcomes than without their use.|
