Cavovarus Foot

This chapter presents a case scenario of a 35-year-old man who presents with ankle instability and overload of the lateral border of his foot. Lateral ligament instability, foot drop, and/or Achilles tendon tightness can be manifestations of Charcot-Marie-tooth (CMT) disorders which conventionally are referred for physiotherapy. Physiotherapy is a simple intervention that may be useful to improve the function of CMT patients. Most authors recommend using peroneus longus to peroneus brevis tendon transfer in the surgical treatment of cavovarus foot to correct forefoot pronation, reduce the first ray plantarflexion and reinforce the weak eversion of the hindfoot. Lateralizing osteotomy is one of the most frequently used osteotomies in the treatment of cavovarus foot. Tarsal tunnel release is recommended before conducting a lateralizing calcaneal osteotomy through lateral approach. The chapter also provides recommendations for implementing evidence-based practice in the clinical setting.
