Adults with a history of clubfoot (congenital talipes equinovarus, CTEV) — or with acquired cavovarus deformity from Charcot-Marie-Tooth disease, cerebral palsy sequelae, or post-traumatic changes — face unique foot care challenges that require subspecialty expertise. At Balance Foot & Ankle, Dr. Tom Biernacki, DPM evaluates and manages adult cavovarus deformity in Howell and Bloomfield Hills, Michigan. Call (810) 206-1402.

Quick Answer: What Is Cavovarus Deformity?

Cavovarus deformity is a combination of: cavus (high arch — excessive plantar flexion of the forefoot relative to the hindfoot, producing a high-arched appearance); varus (heel inversion — the calcaneus tilted inward under the talus); and often equinus (limited dorsiflexion from tight Achilles). The combination creates a foot that bears weight primarily on the lateral border — leading to recurrent lateral ankle sprains, peroneal tendon tears, 5th metatarsal stress fractures, painful calluses over the 5th metatarsal base, and Achilles tendon overload. Residual clubfoot is the most common cause; Charcot-Marie-Tooth disease is the second most common identifiable cause of adult cavovarus deformity.

Recognizing Neurological Causes: CMT and Workup

Any adult presenting with bilateral, progressive cavovarus deformity should be evaluated for Charcot-Marie-Tooth disease (hereditary motor and sensory neuropathy) — the most common inherited peripheral neuropathy, affecting approximately 1 in 2,500 people. CMT produces progressive weakness of the intrinsic foot muscles and peroneal musculature, leading to cavovarus deformity, steppage gait, and frequent ankle sprains. Workup for suspected CMT: nerve conduction studies (reduced motor conduction velocities in CMT type 1; normal velocities with axonal loss in CMT type 2); genetic testing for PMP22 duplication (CMT1A — most common); and neurology consultation for disease management. Identifying CMT changes the surgical planning — deformity correction must account for ongoing progressive muscle imbalance.

The Coleman Block Test: Is the Deformity Flexible or Rigid?

The Coleman block test is the most important clinical examination for cavovarus deformity — it determines whether the hindfoot varus is driven by a plantarflexed first ray (flexible, correctable by forefoot procedure) or fixed at the subtalar joint (rigid, requires hindfoot osteotomy). Technique: place a 1-inch block under the lateral forefoot and heel, allowing the first metatarsal to hang free. If the hindfoot varus corrects to neutral, the deformity is forefoot-driven (flexible). If the varus remains, the hindfoot deformity is rigid. This distinction dictates the surgical approach entirely.

Conservative Management of Cavovarus Deformity

Custom orthotics with lateral heel wedge: Lateral posting of the heel orthotic shifts ground reactive force medially — reducing the varus moment at the subtalar joint and providing partial relief of lateral column overload. This is the primary non-surgical intervention and can be effective for mild-to-moderate flexible deformity. Lateral ankle bracing: Lace-up ankle braces or custom AFO provide mechanical restraint against the recurrent inversion sprains that cavovarus produces. The Arizona Brace or custom molded AFO is appropriate for moderate-to-severe deformity. Footwear modification: Extra-depth shoes with adequate medial support; custom lateral flare midsole modifications to resist inversion.

Surgical Management of Adult Cavovarus

Surgery for cavovarus deformity is guided by the Coleman block test result and deformity severity. For flexible deformity: Plantar fascia release reduces arch height; first metatarsal dorsiflexion osteotomy (Japas or Jones procedure) corrects the plantarflexed first ray driving the varus; peroneal tendon transfer (peroneus longus to brevis or tibialis anterior tendon transfer) corrects the muscular imbalance causing first ray plantarflexion. For rigid hindfoot deformity: Calcaneal lateral closing wedge osteotomy (Dwyer osteotomy) corrects hindfoot varus; combined with forefoot procedures above for complete realignment. Lateral ankle ligament reconstruction is almost universally performed simultaneously — the chronic instability of a cavovarus ankle requires reconstruction of the ATFL and CFL beyond the deformity correction itself. Subtalar or triple arthrodesis is reserved for arthritic, rigid deformities where realignment without fusion is not achievable.

Most Common Mistake with Adult Cavovarus

The most common mistake: treating recurrent lateral ankle sprains in a cavovarus foot with lateral ligament reconstruction alone — without addressing the underlying cavovarus deformity that is causing the recurrent sprains. Isolated ATFL repair in a varus foot has a predictably poor outcome — the repaired ligament is under constant stress from the varus mechanics and fails at higher rates than in a neutral foot. In our clinic, any patient with cavovarus deformity and ankle instability undergoes deformity correction and ankle stabilization as a combined procedure. Addressing only the instability without the deformity is treating the symptom without the cause.

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.
