Posterior ankle impingement is compression of the soft tissue or bony structures at the back of the ankle during plantarflexion (pointing the foot down), causing posterior ankle pain with push-off, descending stairs, and in dancers, ballet positions on pointe. The most common bony cause is an os trigonum — an accessory bone at the posterior talus present in approximately 7–14% of people that becomes symptomatic when repeatedly compressed between the tibia and calcaneus. Dr. Tom Biernacki, DPM at Balance Foot & Ankle in Howell and Bloomfield Hills, Michigan diagnoses and treats posterior ankle impingement.
Anatomy: What Gets Compressed
At maximum plantarflexion, the posterior process of the talus comes into contact with the posterior tibia above and the superior calcaneus below. Three structures can be impinged in this space: the os trigonum (an accessory ossicle that is essentially an ununited posterior talar process, present in 7–14% of individuals), the posterior tibiotalar capsule and synovial tissue, and the flexor hallucis longus tendon that passes through a groove between these bony structures. Repetitive compression during push-off running or forced plantarflexion in dance causes inflammation, scarring, or acute fracture of the os trigonum.
Who Gets Posterior Ankle Impingement
Ballet dancers are the classic population — repetitive pointe work compresses the posterior ankle with every relevé and en pointe position. Runners with a high running volume experience posterior impingement from the push-off phase of each stride. Soccer and football players can sustain acute os trigonum fracture from a direct plantarflexion impact (kicking). The condition also occurs in gymnasts, swimmers (flutter kick), and downhill hikers. The presence of an os trigonum (seen on lateral ankle X-ray) is a predisposing factor but does not mean the patient will develop symptoms — many people have an os trigonum that never causes pain.
Diagnosis
The posterior ankle impingement test — forced passive plantarflexion with the examiner’s thumb on the posterior ankle — reproduces posterior ankle pain in positive cases. Lateral ankle X-ray identifies the os trigonum when present; the bone can appear as a round, well-corticated ossicle posterior to the talus. MRI identifies bone marrow edema within the os trigonum (indicating active stress injury), synovitis in the posterior ankle recess, and FHL tendon involvement. A diagnostic corticosteroid injection into the posterior ankle (guided by ultrasound) provides both diagnosis confirmation and therapeutic benefit.
Conservative Treatment
Activity modification to reduce plantarflexion loading (reduced dance pointe work, modified running form, heel lift to reduce maximum plantarflexion excursion), anti-inflammatory treatment (NSAIDs, ice after activity), and ultrasound-guided corticosteroid injection into the posterior ankle recess are first-line treatments. A heel lift (10–12mm) reduces the maximum plantarflexion demand during gait and can provide significant symptom relief without immobilization. For acute cases with significant inflammation, a 4–6 week period in a CAM boot followed by gradual return to activity is effective.
Surgical Treatment: Os Trigonum Excision
Endoscopic (arthroscopic) os trigonum excision is highly effective for refractory posterior impingement with a confirmed os trigonum. The procedure is performed through two small portals at the posterior ankle under direct arthroscopic visualization. The os trigonum is excised and the surrounding inflamed tissue is debrided. Results are excellent — over 90% of dancers and athletes return to full activity. Recovery: non-weightbearing for 2 weeks, progressive return to sport at 8–12 weeks (athletes), 3–4 months for full ballet return. Open os trigonum excision is occasionally performed for large fragments or concurrent procedures but arthroscopic approach is preferred for most isolated cases.
Most Common Mistake
The most common mistake is treating posterior ankle pain after an ankle sprain as a residual ligament injury for months without lateral X-ray evaluation for os trigonum. Many posterior impingement cases begin after a plantarflexion ankle injury (acute os trigonum fracture) but are misdiagnosed as soft tissue sprain. A simple lateral ankle X-ray identifying the os trigonum, combined with a positive posterior impingement test, establishes the diagnosis and redirects treatment away from ineffective anterior ligament rehabilitation.

Recovery Timeline & What to Expect
Most ankle conditions respond well to the RICE protocol (rest, ice, compression, elevation) in the first 48-72 hours. Beyond that initial window, structured rehabilitation matters more than rest — strengthening the peroneal tendons and reactivating proprioception are what prevent reinjury. Patients who follow Dr. Tom’s guided eccentric exercise protocol typically return to full activity 2-3 weeks faster than those who self-treat.
When surgery is indicated: grade 3 ligament tears, recurrent instability after 6+ months of conservative care, osteochondral lesions, or chronic syndesmotic injuries. We exhaust all non-surgical options first — most patients never need an operating room.
What is Foot pain?
Foot pain is a common foot/ankle condition that affects mobility and quality of life. Understanding the underlying cause is the first step in successful treatment. Our podiatrists at Balance Foot & Ankle perform a hands-on biomechanical exam, review your activity history, and use diagnostic imaging when appropriate to identify the root cause—not just treat the symptom. Many patients have been told to “rest and ice” without a deeper diagnostic workup; our approach is different.
Symptoms and warning signs
Common signs of foot pain include pain that worsens with activity, morning stiffness, swelling, tenderness when palpated, and difficulty bearing weight. If you experience sudden severe pain, inability to walk, visible deformity, numbness or color change, contact our office the same day or visit urgent care—these can signal a more serious injury such as a fracture, tendon rupture, or vascular compromise. Diabetics with any foot wound should seek same-day care.
Conservative treatment options
Most cases of foot pain respond to non-surgical care: structured rest, supportive footwear changes, custom orthotics, targeted stretching and strengthening protocols, anti-inflammatory medications when medically appropriate, and in-office procedures such as ultrasound-guided injections. We also offer advanced therapies including MLS laser therapy, EPAT/shockwave, regenerative injections, and image-guided procedures. Treatment is sequenced from least invasive to most invasive, and we explain the rationale at every step.
When is surgery considered?
Surgery is reserved for cases that fail 3-6 months of well-structured conservative care, when there is structural pathology (severe deformity, complete tear, advanced arthritis), or when imaging shows damage that will not heal without intervention. Our surgeons have performed 3,000+ foot and ankle procedures and prioritize minimally-invasive techniques whenever appropriate. We discuss recovery timelines, return-to-activity milestones, and realistic outcome expectations before any procedure is scheduled.
Recovery timeline and prevention
Recovery from foot pain varies based on severity and chosen treatment path. Conservative cases often improve within 4-8 weeks with consistent adherence to the protocol. Post-procedural recovery may range from a few days (in-office procedures) to several months (reconstructive surgery). Long-term prevention involves footwear assessment, activity modification, structured strengthening, and regular check-ins with your podiatrist if you have a history of recurrence. We provide written home-exercise plans and digital follow-up support.
