Quick Answer
An ankle sprain is a stretch or tear of the lateral ligaments caused by an inward roll of the foot. Grades 1-2 respond to RICE, bracing, and progressive loading within 2-4 weeks. See a podiatrist same-day if you cannot bear weight, have bone tenderness, or severe swelling within 1 hour (Ottawa Rules).

Understanding the Syndesmosis
The ankle syndesmosis is the fibrous joint connecting the distal tibia and fibula — the two bones of the lower leg that form the “mortise” of the ankle joint. The syndesmosis is stabilized by four ligaments: the anterior inferior tibiofibular ligament (AITFL), the posterior inferior tibiofibular ligament (PITFL), the transverse tibiofibular ligament, and the interosseous ligament, which runs the length of the leg between the tibia and fibula. Together, these structures maintain the precise width of the ankle mortise — essential for equal distribution of load across the tibiotalar joint.
A high ankle sprain — correctly termed a syndesmotic sprain — disrupts one or more of these ligaments, potentially widening the mortise and destabilizing the ankle in ways that standard lateral ankle sprains do not.
How High Ankle Sprains Differ from Standard Sprains
Standard lateral ankle sprains — the most common ankle injury — involve the ligaments on the outer side of the ankle (ATFL, CFL). High ankle sprains involve the syndesmotic ligaments above the ankle joint. High ankle sprains typically result from external rotation and dorsiflexion mechanisms — a foot planted while the body rotates externally, as seen in football, skiing, and rugby. The injury mechanism, examination findings, and recovery timeline all differ significantly from lateral ankle sprains.
High ankle sprains are graded by the degree of syndesmotic disruption. Grade I involves AITFL sprain without instability. Grade II involves partial disruption with mild widening. Grade III involves complete syndesmotic disruption with frank instability and mortise widening.
Diagnosis
The squeeze test — compressing the fibula and tibia together at mid-calf — reproduces syndesmotic pain. The external rotation stress test provokes pain at the syndesmosis when the foot is externally rotated while the tibia is stabilized. Weight-bearing X-rays assess mortise width — any widening of the clear space between the medial malleolus and the talus on the mortise view indicates syndesmotic instability. CT scan identifies subtle widening and associated fibular fractures. MRI characterizes ligamentous integrity when X-rays are equivocal.
Non-Operative Management for Stable Injuries
Grade I and some Grade II syndesmotic sprains without mortise widening can be managed non-operatively with immobilization in a boot for four to six weeks followed by progressive rehabilitation. Return to sport from a stable high ankle sprain takes six to twelve weeks — significantly longer than a comparable lateral ankle sprain. Athletes who return too quickly risk developing chronic syndesmotic instability and post-traumatic ankle arthritis.
Surgical Treatment for Unstable Syndesmosis
Traditional Syndesmotic Screw Fixation
One or two large screws are placed across the fibula, through the interosseous membrane, and into the tibia to maintain the reduced syndesmosis while ligamentous healing occurs. The screws are inserted at the level of the tibiotalar joint under fluoroscopic guidance with the ankle in neutral dorsiflexion. Traditional screws are typically removed at eight to twelve weeks, as retained screws across a mobile joint fatigue and break. During the screw removal period, weight-bearing is protected to prevent screw breakage.
Dynamic Fixation: TightRope (Suture Button) Repair
The TightRope construct — a suture button device threaded through drill holes in the fibula and tibia — provides fixation strength comparable to screws while allowing micro-motion at the syndesmosis. This dynamic fixation more closely approximates normal syndesmotic biomechanics than rigid screw fixation and does not require routine hardware removal. Studies comparing TightRope to screw fixation generally show equivalent or superior functional outcomes with TightRope, particularly for athletes who require return to rotational activities.
Direct Ligament Repair
When the AITFL is avulsed with a fibular bony fragment (Tillaux fracture), direct repair or fixation of the fragment is performed in addition to syndesmotic fixation. Primary AITFL suture repair through anchors may be performed alongside bony fixation for complete disruptions in high-demand athletes.
Recovery After Syndesmotic Repair
Non-weight-bearing is maintained for two to four weeks after syndesmotic fixation. Progressive weight-bearing in a boot follows, with transition to regular footwear at six to eight weeks. Athletes undergoing TightRope fixation may avoid screw removal and begin progressive rehabilitation earlier than those with screws. Return to contact sport typically occurs at four to six months. Without appropriate surgical treatment, unstable syndesmotic injuries lead to chronic ankle instability, arthritis, and potentially permanent functional limitation.
Evaluation for Suspected High Ankle Sprain
High ankle sprains are frequently underdiagnosed — the injury mechanism and examination findings distinguish them from lateral sprains, but this distinction requires a knowledgeable examiner and appropriate imaging. If you sustained an ankle injury during external rotation or have persistent ankle pain after a diagnosed “sprain,” contact Balance Foot & Ankle for hands-on exam plus imaging when needed to rule out syndesmotic instability.

Differential Diagnosis: What Else Could It Be?
Several conditions share symptoms with Ankle Sprain and are commonly misdiagnosed in the first office visit. Considering these alternatives is part of every Balance Foot & Ankle exam:
- Peroneal tendon tear. Snapping behind the lateral malleolus or weakness everting the foot.
- High-ankle (syndesmosis) sprain. Pain over the syndesmosis with squeeze + external rotation — needs longer recovery.
- Lateral malleolus fracture. Bone-point tenderness positive on Ottawa rules — get an X-ray.
If your symptoms don’t fit the textbook pattern, ask your podiatrist which differentials they ruled out — that conversation often shortcuts months of trial-and-error treatment.
In Our Clinic
Most of our ankle sprains are acute — a patient comes in the same day or within 48 hours after rolling the ankle. We apply the Ottawa Ankle Rules first: bone tenderness at the posterior malleolus, navicular, or base of the 5th metatarsal, or inability to bear weight for 4 steps, means we image immediately to rule out fracture. For a clean grade 1–2 lateral ligament sprain, we use a short period of boot immobilization if needed, then transition into an ankle brace + proprioception training. The mistake we often see: patients skip the rehab phase and re-sprain within a year.
Most Common Mistake We See
The most common mistake we see is: Returning to sport as soon as the pain resolves. Fix: first pass a 30-second single-leg balance test with eyes closed and complete a graded return-to-sport progression.
Warning Signs That Need Same-Day Care
Seek immediate evaluation at Balance Foot & Ankle if you experience any of the following:
- Unable to bear weight for four steps
- Bone tenderness at the ankle bones (Ottawa)
- Severe swelling within one hour of injury
- Numbness or tingling in the foot

When to See a Podiatrist
A sprain that hasn’t fully recovered after 6 weeks often has residual ligament laxity or occult fracture that keeps the ankle unstable. Balance Foot & Ankle X-rays and stress-tests every lingering sprain — if the ligament is torn, we offer bracing, PRP, and (for chronic instability) minimally-invasive repair. Don’t keep re-rolling the same ankle; let us stabilize it properly.

More questions patients ask
How long does an ankle sprain take to heal?
Recovery time depends on severity: Grade 1 (mild stretching) typically heals in 1-3 weeks, Grade 2 (partial tear) in 3-6 weeks, and Grade 3 (complete tear) in 6-12 weeks or longer. Proper rehabilitation is critical to prevent chronic ankle instability, which affects up to 40% of patients who don't receive adequate treatment. Dr. Biernacki creates customized recovery plans.
When should I see a doctor for a sprained ankle?
Seek professional evaluation if you can't bear weight, notice significant swelling or bruising, hear a pop at the time of injury, have numbness, or if pain hasn't improved after 5-7 days of RICE treatment. X-rays or MRI may be needed to rule out fractures. Dr. Biernacki sees urgent problems. Call 810-206-1402 and we’ll find the soonest opening.
Can a sprained ankle heal without treatment?
While mild sprains may heal with rest and home care, undiagnosed ligament tears and improperly rehabilitated sprains frequently lead to chronic ankle instability, recurrent sprains, and early-onset arthritis. A proper evaluation ensures appropriate treatment and reduces your risk of long-term complications significantly.
