#PES CAVUS DEFORMITY CODE#

6 An imbalance between the antagonistic muscles, in particular the peroneus longus and tibialis anterior, is often listed as a cause. The exact cause in the cavus foot is a longstanding issue, and both intrinsic and extrinsic muscle imbalance may play a role in the final deformity. The posterior cavus or calcaneocavus is characterised by an isolated high calcaneal pitch of greater than 30В° related to a weakness of the gastrocnemius muscle leading to a calcaneus deformity of the hindfoot. Thus, neurological disorders must be looked for in the family history and clinical and electrophysiologica evaluation of the patient is necessary to eliminate any very subtle neurological lesion.

4 In our experience, this primary pes cavus (idiopathic) is diagnosed by elimination in more than half the cases and most authors believe that it is the consequence of a latent neurological disorder. However, in recent years, a mild variation of the cavovarus deformity has been increasingly observed to exist without an identifiable underlying deficit. In most cases, the disease process is progressive rather than static therefore, the deformities worsen and surgical treatment must be considered to prevent the progression to a fixed and symptomatic deformity. CMT IA is the most common form including peripheral nerve myelin degeneration and decreased motor nerve conduction.

Cavovarus deformity has been long associated with neurological disease such as cerebral palsy, Charcot-Marie-Tooth (CMT) disease or other hereditary sensory and motor neuropathies (myelodysplasia, Friedreich ataxia, etc).Д¬MT disease results from defects in the genetic code for the protein of the peripheral myelin sheath and is classified into subtypes varying in progression. Traumatic causes are rare (improperly treated fracture or subluxation of the tarsal bones or scarring from a burn of the sole of the foot). There are many aetiologies of unequal frequency that account for cavovarus foot deformities. 1, 2Д¬avovarus deformity can be classified according to the severity of malalignment ranging from a subtle and flexible cavovarus foot to a severe and fixed cavovarus deformity. A wide spectrum of foot deformities includes a plantarflexed first ray, forefoot pronation and adduction, and hindfoot varus or high calcaneal pitch.

Pes cavus is an increase of normal plantar concavity, where the anterior and posterior weight-bearing areas of the foot are brought closer together. Keywords: cavus foot Charcot-Marie-Tooth disease tendon transfers osteotomy arthrodesis
