High Ankle Sprain (Syndesmotic Sprain)

High ankle sprains are fundamentally different from common lateral ankle sprains: **Location**: High ankle = ABOVE the ankle (syndesmotic ligaments); Lateral ankle = SIDE of ankle (lateral ligaments). **Mechanism**: High ankle = external rotation; Lateral = inversion (rolling outward). **Recovery Time**: High ankle = 2-3x LONGER (weeks to months); Lateral = days to weeks. **Treatment**: High ankle often needs longer immobilization or surgery; Lateral often conservative. **Diagnosis**: Specific tests (squeeze test, external rotation test) for high ankle; standard for lateral. **Imaging**: Weight-bearing X-rays critical for high ankle to assess stability; MRI often needed. **Complications**: High ankle has higher complication rates if untreated. **Sport Implications**: High ankle sprains are career-altering for athletes in some cases. The key takeaway: don't assume your "ankle sprain" is a typical lateral sprain — high ankle sprains need different treatment.

Depends on stability assessment: **Surgery NOT Needed (Most Cases)**: 1) Grade 1 (stable) injuries — conservative treatment effective, 2) Most Grade 2 injuries — depends on stability, 3) No diastasis on X-ray, 4) Stable on stress testing, 5) Recreational athletes with good response to conservative care. **Surgery Likely Needed**: 1) Grade 3 (unstable) injuries, 2) Diastasis on X-ray (>5mm tibiofibular clear space), 3) Maisonneuve fractures, 4) Failed conservative treatment, 5) Elite athletes wanting faster return, 6) Combined injuries. **Modern Surgical Options**: 1) Suture-button (newer, more physiologic), 2) Syndesmotic screws (traditional), 3) Combined procedures. **Decision Made By**: Foot/ankle specialist after imaging and examination. Discussion with surgeon about goals and options is essential.

Several factors contribute to the longer recovery: **Anatomic Reasons**: 1) Syndesmotic ligaments under constant stress during walking, 2) Cannot be completely immobilized, 3) Important for normal ankle function, 4) Heal slowly due to limited blood supply. **Functional Reasons**: 1) Even normal walking stresses ankle, 2) Hard to truly rest the area, 3) Athletic demands particularly stressful, 4) Multiple ligaments often involved. **Treatment Reasons**: 1) Need prolonged immobilization, 2) Surgical recovery extensive, 3) Rehabilitation comprehensive, 4) Return-to-sport criteria strict. **Set Realistic Expectations**: 1) Stable injuries: 2-3 months minimum, 2) Unstable injuries: 3-6 months, 3) Athletic return: 6+ months, 4) Comparison to lateral ankle sprain: 2-3x longer. **Don't Rush Back**: Premature return leads to chronic problems, instability, and possible need for additional surgery.
