posterior talofibular ligament

Abbreviation: PTL
A ligament of the lateral ankle that attaches the posterior portion of the talus, and a portion of the posterolateral calcaneus, to the medial malleolus. The posterior talofibular ligament limits the excessive dorsiflexion and inversion of the talus within the ankle mortise.

Two POEs are used--NRCH (Loring AFB, Maine) and PTFL (McGuire AFB, NJ).
Continuing with the example of Tables 9 through 12, POE NRCH is close enough to PTFL and to several other POEs for RLNs to move to a different triplet using any of these POEs.
(37) Posterior tibiotalar impingement syndrome (PTTIS) can occur in the presence of an os trigonum (Figure 20), a prominent stieda process, or hypertrophy of the transverse ligament (the inferior portion of the PTFL).
The PTFL is the strongest of the lateral ankle ligaments and is rarely injured in ankle inversion sprains.
The PTFL prevents external rotation in dorsiflexion and resists ankle dorsiflexion along with the medial ligaments, which are primarily responsible for these constraints.
