In a patellar tendon bearing (PTB) socket used for a transtibial prosthesis, the principal weight-bearing (pressure-tolerant) areas include all of the following EXCEPT:

• A Patellar tendon
• B Tibial condyles
• C Anterior compartment of the leg (tibialis anterior region)
• D Head of the fibula ✓

Explanation

This item follows Indian exam convention where such 'except' framing is common. Pressure-tolerant areas in the PTB socket are the patellar tendon, tibial condyles, anterior tibial compartment, gastrocnemius belly, and popliteal area. The head of the fibula overlies the common peroneal nerve and is a pressure-intolerant (relief) area, as are the tibial crest, hamstring tendons, and distal tibial end.
