The heel bone (calcaneus) is the architectural cornerstone of the foot. When it drifts outward (in flatfoot) or inward (in high-arch foot), the entire kinetic chain above it — the ankle, knee, hip, and even the low back — compensates inefficiently, leading to pain and accelerated joint wear. A calcaneal osteotomy is the surgical equivalent of realigning a crooked foundation: cut, shift, and stabilize the heel bone into a corrected position.

What Is a Calcaneal Osteotomy?

A calcaneal osteotomy is a surgical cut (osteotomy = bone cut) through the calcaneus that allows the heel to be shifted in a controlled direction and secured with screws or staples in a corrected position. As the bone heals (typically 8–10 weeks), it permanently assumes its new position, changing the mechanical axis of the entire lower extremity. It is a bone-preserving procedure — no joint is fused and no bone is removed — which preserves motion and allows revision options if needed in the future.

Types of Calcaneal Osteotomy

The type of osteotomy is matched to the deformity being corrected. The medializing calcaneal osteotomy (MCO) shifts the heel inward (medially), reducing the valgus (outward-tilting) heel of flatfoot and decreasing stress on the posterior tibial tendon. It is the most commonly performed type and is a cornerstone of adult flatfoot reconstruction. The lateralizing calcaneal osteotomy shifts the heel outward to correct the inverted heel (varus) of cavus (high-arch) foot, reducing peroneal tendon strain and lateral ankle instability. The calcaneal lengthening osteotomy (Evans) opens through the calcaneus and inserts a bone graft to lengthen the lateral column — corrects severe flexible flatfoot in children and young adults. The Dwyer osteotomy removes a lateral wedge to correct rigid varus deformity in cavus foot.

Who Needs a Calcaneal Osteotomy?

Calcaneal osteotomy is indicated for patients with: symptomatic adult-acquired flatfoot with valgus heel deformity failing conservative care (orthotics, bracing); painful cavus foot with varus heel and recurrent lateral ankle sprains; pediatric flexible flatfoot with progression despite conservative management; and certain calcaneal malunions (healed fractures in poor position). The key prerequisite: deformity must be reducible (correctable with surgery) and the subtalar joint must be functional (not fused by arthritis). An arthritic subtalar joint typically requires fusion rather than osteotomy.

Recovery After Calcaneal Osteotomy

The typical recovery pathway: 6–8 weeks non-weight-bearing in a splint then boot (critical for bone healing), 4–6 weeks progressive weight-bearing in a walking boot, 3–4 months transition to regular supportive shoes with custom orthotics, 6–12 months full functional recovery including return to sport. Outcomes for medializing calcaneal osteotomy in adult flatfoot are very good — 80–85% of patients achieve significant improvement in pain, function, and alignment at 2-year follow-up. The procedure is commonly combined with FDL tendon transfer and spring ligament repair for comprehensive flatfoot reconstruction.

Frequently Asked Questions

Is calcaneal osteotomy major surgery? It’s a moderate-complexity procedure performed under regional or general anesthesia. The non-weight-bearing recovery period is significant — 6–8 weeks — but the surgery itself is typically 45–90 minutes. Most patients go home the same day or with one night’s observation.

Will my flatfoot be “cured” by calcaneal osteotomy? Calcaneal osteotomy corrects the mechanical alignment but doesn’t eliminate the underlying tissue laxity. Most patients require custom orthotics long-term post-operatively to maintain correction. The goal is pain relief and prevention of further deformity progression, not cosmetic normalization.

Can the screws be removed? Screws used for calcaneal osteotomy fixation are permanent unless they cause symptoms — pain over a prominent screw head is uncommon but can occur and is easily removed under local anesthesia after the osteotomy has fully healed (typically 6+ months).

The Bottom Line

Calcaneal osteotomy is a powerful, motion-preserving surgical tool for correcting heel alignment in flatfoot and cavus foot. If you’ve been told your foot deformity requires surgery, our team at Balance Foot & Ankle will explain exactly which type of osteotomy — or combination of procedures — addresses your specific alignment problem and what realistic outcomes look like for your anatomy.
