Fig. 3From: Anatomical study of the proximal tibiofibular ligaments using ultrasoundPosterior view of the proximal tibiofibular joint without (a) and with (b) annotations. Muscular structures and lateral collateral and popliteofibular ligaments have been removed. The superior bundle can be seen as a thickening of the PTF joint capsule. The inferior bundle can be seen as a reinforcement emanating from the soleus muscle. SUP: superior bundle of the posterior PTF ligament; MID: middle bundle of the posterior PTF ligament; INF: inferior bundle of the posterior PTF ligament; SL: soleal line; IML: interosseous membrane of legBack to article page
