Deformity Correction
Post-Polio Calcaneovalgus Deformity Correction
A rare post-polio calcaneovalgus deformity corrected through tendon transfer and selective fusion — with equinus deliberately left to balance a weak knee.
Patient Age
32 Years
MECHANISM
Post-polio residual
PRESENTATION
Equinovalgus with Gross Midfoot Planus
APPROACH
Peroneus Longus Transfer, Talonavicular Fusion
01
Clinical Rationale
Detailed muscle-power charting showed absent invertors and weak dorsiflexors. The equinus was deliberately left uncorrected because it was compensating for a weak knee — a decision only the muscle map could justify.
02
Surgical Approach
A peroneus longus transfer to the medial cuneiform was performed with a talonavicular fusion. Equinus was deliberately not corrected, as the equinus was balancing a weak knee — a tailored decision based on the patient's muscle map.

Imaging & Progression
Pre-operative imaging, intra-operative views and post-operative results. Each slot maps to a CMS image field — drop in the matching consented file from the case folder.
#1
Polio deformities are quite common as residues of the disease.
#2
Calcaneovalgus is a rare but challenging polio deformity.
#3
Bony plus soft-tissue balancing are the denominators of success.
#4
Equinus may be deliberately preserved when it compensates for a weak knee.

Post-Polio Calcaneovalgus Deformity Correction
A rare post-polio calcaneovalgus deformity corrected through tendon transfer and selective fusion — with equinus deliberately left to balance a weak knee.
A 32-year-old man with previous poliomyelitis presented with a severe left calcaneovalgus and planus deformity. The tibialis-anterior and tibialis-posterior muscles were weak or absent, while the peroneal muscles continued to pull the foot outward. The challenge was to rebalance the foot without removing the equinus position that helped compensate for a weak knee.
