For polio survivors, surgical correction of foot deformities such as equinus and cavovarus is a functional necessity rather than a cosmetic one. The core objective is to create a stable, plantigrade (flat) platform by rebalancing the muscular forces, often through tendon transfers, and/or solidifying the foot's structure with osteotomies or arthrodesis (joint fusion). This significantly reduces pain, prevents skin breakdown and ulcers, improves the fit and function of ankle-foot orthoses (braces), and dramatically enhances overall standing and walking stability. It is crucial to understand that the goal is not to cure the polio weakness but to make the limb more mechanically efficient and manageable. The recovery is demanding, typically involving a long period in a non-weight-bearing cast to protect the bony work, followed by extensive gait retraining. While these procedures rarely restore "normal" function, patient satisfaction is often high due to the achieved gains in independence, reduced pain, and decreased reliance on bracing.
