MRI scans of the lumbar spine in lower back pain—why are we missing the elephant in the room?

Lower back pain (LBP) is a leading cause of disability worldwide and a major contributor to healthcare costs. Diagnosing non-specific mechanical LBP remains difficult and often relies on exclusion. Current magnetic resonance imaging (MRI) reports typically emphasize disc degeneration, an age-related and often asymptomatic finding, while overlooking more clinically relevant factors like the state of the muscle. Fat infiltration and muscle wasting seen on MRI scans are common in LBP patients and are potentially reversible with targeted exercise rehabilitation. In a recent case, MRI revealed significant fat infiltration and muscle atrophy, yet the report focused solely on disc changes, missing the elephant in the room: the correctable muscular dysfunction. Since exercise is the cornerstone of LBP management, ignoring modifiable muscle health while highlighting irreversible and non-pathological age-related changes limits targeted treatment guidance. Routine reporting of muscle condition could lead to more precise rehabilitation and improved patient outcomes.
