This classification system categorizes patients presenting with low back pain into one of three categories: non-specific low back pain, radicular syndromes, or serious pathology.1234 However, some guidelines endorse a simpler two-category approach that classifies presentation as either low back pain with or without radicular pain, or serious pathology.56
<3>Limitations of the Current Classification System
Despite its long use, the current classification system has several limitations. It may be too simplistic to guide satisfactory diagnostic work-up, and it does not acknowledge the category for patients whose low back pain arises from a non-spine condition. Such conditions include renal and gastrointestinal disorders, other musculoskeletal conditions (such as hip osteoarthritis), and fracture beyond the lumbar spine, all of which can present as low back pain.
<3>The Importance of Non-Spine Causes
Most guidelines do not acknowledge the category for patients whose low back pain arises from a non-spine condition. This is a significant oversight, as non-spine causes can be
