Rationale for change
There's no such thing as the "posterior tibial nerve" (in the same way that there is no "anterior" tibial nerve)-- it's just "tibial nerve" by international anatomical terminology (https://pubmed.ncbi.nlm.nih.gov/31804758/). However, you don't really purcuss a nerve-- you percuss the area above it. UWorld Step 2 qid:19927 describes a physician illiciting a positive Tinel test by percussing the "posterior medial malleolar area". This is more accurate. Moreover, giving the user the word "tibial nerve" is a dead giveaway for tarsal tunnel syndrome.

- Due to compression of the tibial nerve by the flexor retinaculum
- The main risk factor is trauma (e.g., fracture of calcaneus or medial malleolus)
- Another risk factor is tensile stress (e.g., pes planus, other deformities)
- The pain may also be reproduced with dorsiflexion–eversion and plantar flexion–inversion of the ankle
