Bernt Hardy Stage 2 is characterized by which finding?

• A. Small subchondral compression
• B. Partial fragment detachment
• C. Complete detachment but not displaced
• D. Displaced fragment

Answer: (B)

In this classification, the progression of osteochondral lesions of the talar dome is based on how much of the fragment is detached. The second stage specifically shows a fragment that is only partly detached from the underlying bone, meaning there is partial detachment rather than a complete separation or displacement. This distinguishes it from the first stage (subchondral compression without detachment), the third stage (completely detached but nondisplaced), and the fourth stage (displaced fragment). So the hallmark finding is a partially detached osteochondral fragment.
