A key feature distinguishing a Romanus lesion is its dual nature showing both damage and what reparative sign?
Answer
Sclerosis
A definitive characteristic that helps isolate the Romanus lesion from other types of spinal injury is its inherent dual pathology reflecting the chronic nature of Ankylosing Spondylitis. While the process begins with destructive erosion of the bone at the enthesis, the body simultaneously mounts a strong reparative response. This repair involves osteoblasts laying down new, dense bone tissue, which is observed radiographically as sclerosis—a denser, whiter appearance compared to surrounding bone. The presence of both erosion and reactive sclerosis defines this specific feature of AS spinal involvement.
