What are the MRI findings in Wilkes stage V?

• A. Anterior disc displacement and normal structures
• B. Anterior disc displacement and perforation
• C. Gross deformity of the disc and normal bone structures
• D. Gross degenerative changes of both disc and osseous structures

Answer: (D)

Wilkes stage V represents a severe stage of temporomandibular joint (TMJ) disorders where there are significant degenerative changes. At this stage, MRI findings typically show extensive changes not only in the disc but also in the osseous structures of the joint. These degenerative changes can include erosion of the condylar head, flattening of the articular surface, and significant destruction of the disc's integrity. In contrast to the earlier stages of Wilkes classification, which might show disc displacement without severe structural changes, stage V indicates that the pathology has advanced to the point where the integrity of both the disc and the surrounding osseous structures is compromised. This is evidenced by findings of advanced arthritis or osteoarthritis that affects both the disc and the bone structures, often accompanied by pain and limitation of movement. The other choices reflect conditions associated with earlier Wilkes stages, where abnormalities are limited to disc displacement or minor changes rather than the extensive damage seen at stage V.
