What established lesion results from the maturation and extensive repair of an initial Romanus lesion?
Answer
Andersson lesion
The development of a Romanus lesion is progressive. When the initial lesion, characterized by marginal erosion and mild reactive sclerosis, persists over a long duration, the reparative mechanism often becomes far more pronounced. This maturation process results in what is termed an Andersson lesion. Andersson lesions are essentially Romanus lesions that have undergone extensive reactive bone formation, leading to larger, more substantial, and densely sclerotic areas specifically located at the vertebral corners, signifying a long-standing pattern of disease activity in that spinal segment.
