05-01-202605-01-2026<p>Cavus foot deformity involves a whole spectrum of deformities defined by fixed equinus of the forefoot on the hindfoot, resulting in a pathologic elevation of the longitudinal arch, with either a fixed or flexible hindfoot deformity. This entity is prevalent in approximately 25% of the population. The presence of a cavus foot could be the presenting sign of an underlying neurologic disorder. The most common is a form of hereditary sensory-motor neuropathy known as Charcot Marie tooth polyneuropathy. A thorough clinical and radiographic examination is mandatory to determine the appropriate treatment for each patient. Treatment typically begins with nonsurgical measures; however, in progressive or severe rigid deformities, surgical procedures must be performed in a staged protocol to avoid deformity or symptoms progression and the worst prognosis. Surgical techniques include soft tissue procedures, osteotomies, and fusions, tailored to each patient's deformity.</p>info:eu-repo/semantics/restrictedAccessAchilles lengtheningArthrodesisCalcaneal osteotomyCavus footForefoot osteotomyMidfoot osteotomyMinimally invasive surgeryPolyneuropathyTendon transferChapter
