Club Foot

Q: What are the arches of the foot? How they are formed?
A) Longitudinal arch:
a) Medial longitudinal arch
b) Lateral longitudinal arch
B) Transverse arch:
a) Anterior transverse arch
b) Posterior transverse arch
Medial longitudinal arch:
Anterior end Heads of the 1st, 2nd and 3rd metatarsal bone.
Posterior end Medial tubercle of the calcaneum.
Summit Superior articular surface of the body of the talus.
Pillars Anteriorly by the talus, navicular, three cuneiform and first
three metatarsal bones. Posteriorly by the medial part of the
calcaneum.
Main joint Talo-calcaneo-navicular joint.
Lateral longitudinal arch:
Anterior end Heads of the 4th and 5th metatarsal bone.
Posterior end Lateral tubercle of the calcaneum.
Summit At the level of the subtalar joint.
Pillars Anteriorly by the cuboid and 4 th and 5th metatarsal bones.
Posteriorly by the lateral half of the calcaneum.
Main joint Calcaneo-cuboid joint.
Anterior transverse arch:
Formed by the heads of the five metatarsal bones.
Posterior transverse arch:
It is incomplete and formed by the greater parts of the tarsus and
metatarsus.
Q: What is the deltoid ligament? What are its parts?
It is the medial ligament of the ankle joint, triangular in shape and is very
strong.
It has two parts:
a) Deep part (Anterior tibio-talar)
b) Superficial part:
a. Anteriorly Tibio-navicular
b. Middle Calcaneo-tibial
c. Posteriorly Posterior tibio-talar

Q: What is spring ligament?


It is also called planter calcaneo-navicular ligament. It is attached
posteriorly to the anterior margin of the sustentaculum tali and anteriorly
to the planter surface of the navicular bone. The head of the talus rests
directly over the upper surface of the ligament. It is the most important
ligament for maintaining the medial longitudinal arch of the foot.
Q: What is master knot of Henry?
It is a very thick and heavy structure made up of fibrous tissue and
cartilage which extends from the navicular bone around the flexor
digitorum longus and flexor hallucis longus tendons to reattach to the
navicular bone or fascia of the flexor hallucis brevis. The knot is included
sometimes in a large mass of scar tissue and cartilage which is partly
attached to the navicular bone and medial malleolus and may be the
primary tissue holding the navicular bone in its displaced position.
