Posterior ankle impingement near Farmington Hills is often driven by a small extra bone called the os trigonum that 1 in 10 people has and never knew about — until one specific movement triggers it. A single targeted injection confirms the diagnosis and often resolves the pain; if not, arthroscopic removal takes under an hour.

Posterior Ankle Impingement Treatment Near Farmington Hills, MI

Call (810) 206-1402.
Pain When Pointing the Foot: Posterior Ankle Impingement
Posterior ankle impingement occurs when soft tissue or bony structures are compressed between the posterior tibia and calcaneus during plantarflexion (pointing the foot). The most common cause is an os trigonum — an accessory ossicle behind the talus present in 7–14% of the population — which becomes symptomatic when repetitive plantarflexion traps it between adjacent bones. Soft tissue impingement from posterior capsule thickening (often post-sprain) can produce identical symptoms. The characteristic presentation: posterior ankle pain specifically with forced plantarflexion — going downstairs, wearing heels, pushing off in sports. In our Farmington Hills-area patients, this injury is particularly common in dancers and soccer players, and is frequently mislabeled as Achilles tendinopathy or “posterior ankle tendinitis.”
Key Takeaway: X-ray identifies an os trigonum; MRI confirms whether it is the active pain source (bone marrow edema signal). A diagnostic injection confirming pain relief localizes the impingement. Arthroscopic excision has excellent outcomes — 6–8 week return to sport — with superior recovery compared to open surgery.
Treatment
Conservative treatment: Activity modification avoiding forced plantarflexion. Heel lift reduces posterior impingement stress. Fluoroscopy or ultrasound-guided corticosteroid injection into the posterior ankle — both diagnostic and therapeutic. Approximately 50–60% achieve sufficient relief with injection and activity modification. Arthroscopic surgery: Posterior ankle arthroscopy via posteromedial and posterolateral portals allows direct visualization and excision of the os trigonum and soft tissue impingement. Minimal-invasive technique with excellent outcomes. Most patients return to full sport in 6–8 weeks.
⚠️ See a Podiatrist If:
- Posterior ankle pain specifically worsened by pointing the foot down
- Pain going downstairs or wearing high-heeled shoes
- Posterior ankle pain in a dancer, gymnast, or soccer player
- “Posterior ankle tendinitis” not resolving with standard conservative treatment
- MRI or X-ray shows an os trigonum with clinical symptoms correlating to the finding
Recommended Products for Ankle Impingement Recovery
Reducing anterior or posterior ankle impingement pain at home starts with the right support. Dr. Biernacki recommends these clinically appropriate products for our patients managing ankle impingement symptoms.
ASO Ankle Stabilizing Orthosis Brace
The ASO brace is the gold standard for ankle support used in our clinic. Its lace-up design with figure-eight straps limits excessive dorsiflexion and plantarflexion — the movements that provoke impingement pain. Lightweight enough for all-day wear inside regular shoes. Available in multiple sizes.
Bauerfeind MalleoTrain Ankle Support
Medical-grade knit compression sleeve with anatomical inserts that apply targeted massage to the ankle joint during movement. Reduces swelling, improves proprioception, and decreases soft tissue irritation around the ankle. Excellent for patients with posterior impingement who need compression with mobility. Machine washable.

📋 Dr. Tom Biernacki, DPM, FACFAS answers:
Posterior ankle impingement near Farmington Hills causes pain at the back of the ankle during plantarflexion — pointing the foot down. It is common in ballet dancers, soccer players, and anyone who repeatedly loads the posterior ankle. Our podiatrist serving Farmington Hills identifies contributing factors such as an os trigonum (an accessory bone), a prominent posterior talar process (Stieda process), or hypertrophic soft tissue. Conservative treatment includes rest, ice, anti-inflammatory medications, physical therapy, and cortisone injections. When an os trigonum or bony prominence is identified and symptoms persist, arthroscopic excision is performed through small posterior portals. Recovery is typically four to six weeks. Patients near Farmington Hills who undergo surgery experience high satisfaction rates and return to their sport or activity without restriction.

More questions patients ask
What causes posterior ankle impingement syndrome?
Posterior ankle impingement occurs when soft tissue or a bony prominence (often an os trigonum — an accessory bone behind the ankle) is compressed between the tibia and calcaneus during plantarflexion (pointing the foot downward). It's the classic 'ballet dancer's ankle' injury, but also affects soccer players who repeatedly plantarflex at impact. The os trigonum is present in 7% to 14% of people and remains asymptomatic until a specific forceful plantarflexion movement triggers compression and inflammation.
How is posterior ankle impingement treated?
Initial treatment involves activity modification to avoid forced plantarflexion, anti-inflammatory medications, and a corticosteroid injection into the posterior ankle space to reduce inflammation around the impinged tissue or os trigonum. Physical therapy addresses calf flexibility and posterior ankle joint mechanics. When an os trigonum is confirmed as the source and conservative treatment fails after 3 to 6 months, surgical excision of the os trigonum — either arthroscopically or through a small open incision — provides reliable and often rapid relief.
How long is recovery after os trigonum removal surgery?
Arthroscopic os trigonum excision allows weight bearing within days and return to sports at 6 to 10 weeks in most cases. Open surgical removal typically requires 2 to 3 weeks non-weight bearing and return to sport at 3 to 4 months. Results are generally excellent — most athletes return to full activity at their pre-injury level. Early postoperative physical therapy focusing on range of motion and strength recovery is important for optimal outcomes.
