High ankle sprain
[citation needed] In this sequence of events, the most vulnerable structure is the anterior inferior tibio-fibular ligament, uniting the lower end of the tibia and fibula and playing an important role in the maintenance of the mortise.However, should these structures fail, then the force will be transmitted beyond the anterior inferior tibiofibular ligament to the strong membrane that holds the tibia and fibula together for most of their length.[5] Consequently, a diagnostic modality such as ultrasound or magnetic resonance imaging (MRI)[4] that demonstrates the ligament itself may be helpful, if clinical suspicion remains.ankle rehab treatment suggests not icing the injury, and instead, following more proactive rehab techniques for recovery: "when ice is applied to a body part for a prolonged period, nearby lymphatic vessels begin to dramatically increase their permeability (lymphatic vessels are 'dead-end' tubes which ordinarily help carry excess tissue fluids back into the cardiovascular system).A significant percentage of these sprains also involve medial and/or lateral ankle ligament injury and slow recovery and continuing symptoms are common.[1] However, limiting external rotation to protect healing ligaments is a primary concern and can usually be achieved by short leg casts, walking boots, and custom orthoses.[7] Early resistance exercise minimizes muscle atrophy and weakness and a variety of exercises—elastic bands, ankle weights, heel raise exercises—may be used in conjunction with a calf stretch.
