CLINICAL INSIGHT

When to Use

Evaluating suspected "high ankle sprain" (syndesmotic injury).
Differentiating between stable (Grade I) and unstable (Grade II/III) injuries.
Guiding the decision for surgical stabilization vs. conservative bracing.

Mechanism of Injury

Typically forced external rotation of the foot with the ankle in dorsiflexion, causing the talus to widen the mortise.

How it Works

Clinical Tests

Squeeze Test

ER Stress Test

Cotton Test

Fibula Translation

Grading System

Grade I: Isolated injury to AITFL without instability.
Grade II: Partial tear of syndesmotic complex; dynamic instability.
Grade III: Complete disruption (AITFL, PITFL, IO membrane); gross instability.

CLINICAL INSIGHT

Practical Pearls

Radiographic Criteria

Medial Clear Space > 4mm (Stress view).
Tibiofibular Overlap < 6mm (AP view).
Tibiofibular Clear Space > 6mm (AP/Mortise view).

Clinical Pearls

Recovery time for high ankle sprains is typically 2x longer than lateral sprains.
Weight-bearing radiographs are essential to assess subtle diastasis.
Tenderness that extends >6cm proximal to the joint line is predictive of a longer recovery (>6 weeks).

CLINICAL INSIGHT

Next Steps

Management Decisions

Grade I (Stable): Non-weight bearing 1-3 weeks, then progressive rehab in a stirrup brace.
Grade II (Latent): Consider MRI or stress X-ray. If widening exists, surgical fixation (tightrope/screws) is indicated.
Grade III (Unstable): Surgical stabilization required to prevent early arthrosis.
