Functions of the foot
•Static functions: - Lateral column of the foot: calcaneus, cuboideum, IV, V metatarsus → weight bearing, support •Dinamic functions:
- Medial column of the foot: talus, naviculare, cuneiform I, II, III → walking, energy absorption

Muscles responsible for holding
the longitudinal arch:
•posterior tibial muscle
•flexor digitorum longus muscle
•flexor hallucis longus muscle
•peroneal muscle
Muscles responsible for holding
the transversal arch :
•adductor hallucis muscle
•long peroneal muscle
•anterior tibial muscle

• Pes equinus (talpies equinus): plantarflexion in the talocrural joint
• Pes calcaneus: the foot is in dorsal extension
• Pes cavus (excavated foot): forefoot is in flexion compared to the hindfoot, high longitudinal arch
Deformities in the saggital plane
10/66
• Pes varus: the calcaneus turns inward at the subtalar joint
• Pes valgus: the calcaneus turns outward at the subtalar joint
• Pes adductus (metatarsus varus, intoe): the forefoot turns medially in the Chopart-joint
• Pes supinatus (inverted foot): the forefoot is in supination in the Chopart-joint
• Pes abductus: the forefoot turns laterally in the Chopart-joint
Deformities in the frontal plane

Treatment of pes planus (flat foot)
Prevention:
•Walking on uneven surface;
•Pick up the child, when tired;
•Foot-gymnastic
In childhood:
•gymnastic
•shoe sole – supinating wedge
•surgery
Adulthood, in case of complain:
•shoe sole
•surgery

Pedes transversoplani
(flattened transversal arch)
• Leads to:
– metatarsalgia
– toe deformities (hammer toe, hallux valgus)
• Treatment: gymnastic, shoe sole, surgery

Hallux valgus
• 1. Lateral deviation of
the hallux
• 2. Medial deviation of
the I. MT
• 3. Pronation of the
hallux
57/66
Treatment:
• Hallux valgus correction orthesis
• Shoe sole
• Orthopedic shoes
• Surgeries: soft tissue - surgery, removing
exostosis, osteotomies, arthrodesis,
resection arthroplasties
