Tibiofibular Ligaments

Anterior Tibiofibular Ligament

Attaches the Anterior Distal Tibia to the anterior Distal Fibula

Posterior Tibiofibular Ligament

Attaches posterior tibia

to the posterior fibula

Extensor Retinacula

Goes across the ankle and attaches medially to the tibia and laterally to the fibula.

Plantar Ligaments

Long Plantar Ligament Goes from calcaneus to 2-

4 metatarsels Short Plantar Goes off the side of the

long plantar ligament

Plantar Aponeurosis

Goes over the long and short plantar ligaments

Interrosseous ligament

Runs between the tibia and the fibula

Plantaris

O-Posterior lateral condyle of femur

I-Posterior calcaneus A-Weak assist in knee flex;

ankle plantar flexion IN-Tibial nerve, popliteal

artery

Tibialis Anterior

O-Lateral tibia and interosseous membraneI-1st Cuneiform and metatarsalA-Ankle inversion and dorsiflexionIN-Deep peroneal nerve; Anterior tibial artery

Tibialis Posterior

O-Interosseous membrane; adjacent tibia and fibulaI-Navicular and most tarsels and metatarselsA-Ankle inversion; assists in plantarflexionIN-Tibial nerve ; Fibular artery

Peroneus Longus

O-Lateral proximal fibula and interosseous membrane

I-Plantar surface of 1st cuneiform and metatarsal

A-Ankle eversion; assists in ankle plantarflexion

IN-Superficial peroneal nerve; fibular artery

Plantar Fasciitis•The plantar fascia (or plantar aponeurosis) is the thick connective tissue which supports the arch of the foot.

•It runs from the tuberosity of the calcaneus forward to the heads of the metatarsal bones. It is the source of plantar fasciitis.

•The plantar fascia supports the arch of the foot by acting as a tie-rod, where it undergoes tension when the foot bears weight.

•When tension becomes too much, small tears are made in the fascia. Repeatitive tearing and stretching create an inflamed and painful area.

•Most people complain of symptoms in the morning, or after exercising like jogging of playing tennis.

Causes of Plantar Fasciitis

•Physical activity •Improper shoes

•Diabetes

•Arthritis

•Heredity

Prevention

Maintain healthy weight Stay away from those old beat-up

tennis shoes Begin any sport activity slowly Stretch in the morning and

throughout the day

Treatments

Night splints – helps keep fascia from contracting during the night.

Orthotics – may help distribute weight more evenly on the feet.

Physical therapy – instruction for strength training exercises for LE.

Corticosteroids – provide temporary relief.

Surface Anatomy

•Calcaneal tendon also known as the Achilles tendon.

•Lateral malleolus

•Medial malleolus

Surface Anatomy

•Extensor digitorum longus tendon•Extensor Hallucis longus tendon•Tibialis anterior tendon•Extensor hallucis brevis tendon•Fibularis longus tendon(Peroneus longus)

Surface Anatomy

Great Saphenous Vein originates from where the dorsal vein of the large toe merges with the dorsal venous arch of the foot.

Surface Anatomy Site of Dorsalis Pedis

The dorsal pedis pulse can be palpated laterally to the extensor hallucis longus tendon on the top surface of the foot.

Doctors use this site to determine if a patient has peripheral vascular disease.

Flexor Hallucis Longus O: Posterior fibula and

intersseous membrane I: Distal phalanx of big toe A: Flexes big toe; inversion & plantar flexion of ankle I: Tibial nerve V: Fibular artery
