pes cavus
Last reviewed 01/2018
In pes cavus, the longitudinal arch of the foot is higher than normal. There is often also a clawing of the toes as weight is taken on the metatarsal heads when walking.
It may be the result of neurological disorders where the intrinsic muscles are weak or paralysed. Idiopathic pes cavus may be due to a similar muscle imbalance.
