pes cavus

high-arched or claw foot. An acquired or congenital condition, which results from plantarflexion of the forefoot relative to the rearfoot, with elevation of the longitudinal arch. Associated with clawing of the toes, depression of the first metatarsal and hindfoot varus. May be the result of underlying neuromuscular disease. Can present with pain, difficulty in getting suitable shoes or obvious foot deformity. In sport, good podiatry input and correctly fitted shoes will minimize secondary effects, which are seen primarily in weight-bearing sports.

pes cavus

; cavus foot idiopathic or neurological, fixed or mobile foot deformity; characterized by increased sagittal height of medial longitudinal arch, and variable degrees of tendo Achilles contracture (functional ankle equinus) and non-reducible rearfoot varus, forefoot equinus, partial or total forefoot valgus, plantarflexion and varus adduction (toward midline of body) of first metatarsal, hallux abductovalgus, triggered hallux (+ associated soft-tissue and nail lesions), clawing of lesser toes (+ associated soft-tissue and nail lesions), decreased plantar contact area/increased plantar pressures + hyperkeratotic lesions (at first + fifth or 2/3/4 metatarsophalangeal joints and basal fifth metatarsal areas), plantar fasciitis, heel pain and plantar enthesiopathy, and difficulty in obtaining shoes that fit/do not traumatize the foot; neurological causes of pes cavus include poliomyelitis, juvenile idiopathic arthritis, spina bifida occulta, Charcot-Marie-Tooth disease, hereditary motor and sensorimotor neuropathies, Friedreich's ataxia and spinal cord tumours (see Table 1 Figure 1; Box 1)
Box 1: Characteristics of pes cavus
  • Limited or reduced subtalar joint range of motion, especially frontal-plane motion

  • General reduced range of motion of all foot joints

  • Increased angulation of the calcaneum, metatarsals and phalanges relative to the support surface

  • Decreased angulation of the talus and navicular, relative to the support surface

  • Retraction of the toes, and trigger deformity of first toe

  • Inversion of the rearfoot and rearfoot instability

  • Reduced plantar contact area and increased forces in those areas of the plantar skin that are in contact with the ground surface

  • Decreased or lost ankle joint dorsiflexion

  • Signs of other neuromuscular pathologies in the patient or in other members of the patient's family

The incidence of stress fractures in cavus foot is believed to be secondary to the more rigid, reduced shock absorbency of this type of foot (Korpelainen et al.
