Consequences of an Acute Ankle Sprain • Most commonly injured structures in 547 patients with soft tissue • Most common clinical injuries due to an acutely twisted presentations ankle – ATFL + CFL = 34% – Presented to emergency room or occupational medicine clinic – ATFL + CFL + PTFL = 31% – ATFL only = 16% – Other = 14% • “Injury” based on pain at site of structure – PTFL only = 2% – CFL only = 1% – Anterior Talofibular Lig. (83%) – Calcaneofibular Lig. (67%) • Most common primary diagnoses – Posterior Talofibular Lig. (34%) – Grade 1 sprain = 71% – Deltoid Lig. (32%) – Other = 15% – Ankle joint capsule (32%) – Grade 2 sprain = 10% – Dorsum of foot (20%) – Grade 3 sprain = 3% – Sinus tarsi (16%) – Syndesmotic sprain = 1% – Peroneals (15% – Bifurcate Lig.

14 The Future of Acute Ankle Sprain Footbeat in Action Treatment Intervention?

International Ankle Consortium Rehabilitation-Oriented ASsessmenT (ROAST)

• The International Ankle Consortium ROAST will help clinicians identify mechanical and/or sensorimotor impairments that are associated with chronic ankle instability (CAI). ROAST • This consensus statement from the International Ankle Consortium aims to be a key resource for clinicians who regularly assess individuals with acute lateral ankle sprain injuries.

15 OTTAWA ANKLE RULES OTTAWA ANKLE RULES • Developed to reduce the use of unnecessary radiographs in the diagnosis of acute foot and ankle injuries in emergency departments • Estimated only 15% of foot/ankle injuries presenting to emergency departments are fractures • Use of these diagnostic rules have significantly reduced unnecessary x-rays

Tibial Plafond - the Did this really happen? Ankle Fractures articular surface of the distal end of the tibia.

• Ankle fractures are usually defined as single malleolar, bimalleolar, or trimalleolar

Trimalleolar involves med/lat and posterior tibial malleolus • Isolated fibular fractures are the most common type of fracture and, without displacement, usually requires 4-6 weeks to heal

21 Ankle Dislocation Posterior Malleolar Fracture • Ankle dislocation results from complete disruption of articular elements in the ankle • An isolated ankle dislocation without associated fracture is quite rare

What Does the Evidence Suggest?

• None of the syndesmotic stress tests could distinguish which ligaments were sectioned. Furthermore, the small displacements measured during the stress tests (with the exception of the external rotation test) suggest it is unlikely that the displacement induced in injured syndesmoses can be clinically differentiated from normal syndesmoses. Therefore, pain, rather than ??? ??? increased displacement, should be considered the outcome measure of these tests. – Beumer A, van Hemert WL, Swierstra BA, Jasper LE, Belkoff SM.
