The subtalar joint — the articulation between the talus and calcaneus — is the primary joint governing foot inversion and eversion. Subtalar joint injections serve both diagnostic and therapeutic purposes, providing targeted corticosteroid delivery for subtalar arthritis, synovitis, and post-traumatic inflammation that fails to respond to oral anti-inflammatory therapy.
Anatomy and Clinical Significance
The subtalar joint complex consists of three facets: the posterior, middle, and anterior facets. The posterior facet is the largest and most clinically relevant, accountable for the majority of subtalar motion. The sinus tarsi — a fatty recess lateral to the posterior subtalar facet — is the standard injection access point and the site of sinus tarsi syndrome, a common source of lateral hindfoot pain following inversion sprains.
Indications for Subtalar Injection
Primary indications include subtalar osteoarthritis (isolated or post-calcaneal fracture), sinus tarsi syndrome, subtalar synovitis from inflammatory arthropathy (rheumatoid, psoriatic, gout), and diagnostic injection when subtalar versus ankle pathology is unclear. Subtalar injections may also precede or follow subtalar fusion decisions to confirm the joint as the pain generator and assess functional significance of motion loss.
Injection Technique
The standard approach targets the sinus tarsi via a lateral approach with the patient supine or in lateral decubitus position with slight plantar flexion and inversion of the foot. The needle is directed anteriorly and slightly medially into the sinus tarsi. Fluoroscopic or ultrasound guidance significantly improves accuracy — blind injection accuracy is reported at only 50–65% versus 90–95% with image guidance. Dr. Biernacki performs subtalar injections under diagnostic ultrasound guidance for precise delivery.
Corticosteroid vs. Viscosupplementation
Corticosteroid injections (typically triamcinolone acetonide 20–40mg or methylprednisolone acetate 40mg with local anesthetic) provide rapid symptom relief lasting weeks to several months. Viscosupplementation with hyaluronic acid derivatives has shown benefit in small series for subtalar arthritis, though evidence is less robust than for the tibiotalar or knee joint. PRP injection is an emerging option for recalcitrant subtalar synovitis without significant structural arthritis.
Expected Outcomes and Frequency
Most patients experience meaningful pain relief within 3–5 days of corticosteroid injection, with duration of relief correlating with underlying structural severity. Injections are typically limited to 3–4 per year per joint to minimize risk of cartilage degradation and periarticular tissue atrophy. A positive diagnostic response (50%+ pain reduction) to subtalar injection confirms the joint as the primary pain source and is valuable information when considering subtalar fusion.

When to See a Podiatrist
Cortisone injections are most effective when paired with a root-cause fix — orthotic, shoe change, or physical therapy. At Balance Foot & Ankle, we use ultrasound guidance to place every injection exactly in the inflamed space, maximizing relief. And we always discuss the treatment plan that follows, so the pain stays gone.

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.
