About This Presentation

Description : Check out this medical PowerPoint presentation titled "Foot and Ankle, Anatomy and Injuries”.

This medical PowerPoint presentation is about foot and ankle injuries. The foot and ankle are complex structures that contain numerous bones, joints, muscles, and ligaments. The foot consists of 26 bones, including the heel bone (calcaneus), the ankle bone (talus), and five metatarsal bones, while the ankle joint is formed by the meeting of the tibia and fibula bones with the talus.

Some common injuries that can occur in the foot and ankle include:

Sprains: These occur when the ligaments that hold the bones together are stretched or torn, typically from a sudden twisting motion. Ankle sprains are one of the most common types of sprains.
Fractures: A fracture refers to a broken bone. Fractures in the foot and ankle can occur from a variety of causes, such as a fall, a direct blow, or overuse.
Tendinitis: This is an inflammation of the tendons, which are the tough bands of tissue that connect muscles to bones. Tendinitis in the foot and ankle can be caused by overuse or injury.
Plantar fasciitis: This is a condition in which the plantar fascia, a band of tissue that runs along the bottom of the foot, becomes inflamed. It is often caused by overuse, such as running or standing for long periods of time.
Achilles tendinitis: This is an inflammation of the Achilles tendon, which connects the calf muscles to the heel bone. It is often caused by overuse, such as running or jumping.

Treatment for foot and ankle injuries will depend on the specific injury and its severity, but may include rest, ice, compression, elevation, and physical therapy. In some cases, surgery may be necessary to repair the damage.

Slide 1-

Unit 5:Understanding Athletic-Related Injuries to the Lower Extremity Foot and Ankle, Anatomy and Injuries Sports Medicine
Slide 2-

The Foot and Ankle
Slide 3-

The Foot (Bones) Bones = 26 14 phalanges 5 metatarsals 7 tarsals
Slide 4-

Toes (Phalanges) Designed to give wider base for balance and propelling the body forward. 1st toe (Hallux) Two sesamoid bones located under the 1st MP joint.
Slide 5-

Metatarsals 5 Bones 1st metatarsal is the largest and strongest and functions as the main body support during walking and running. Palpable at the ball of the foot. 5th metatarsal most common fractured.
Slide 6-

Tarsals 7 bones Aids in the support of the body. Calcaneous = largest tarsal bone, supports talus and shapes heel, and provides attachment for achilles tendon.
Slide 7-

Joints of the Foot Interphalangeal joint (IP) Flexion / Extension Metarsalphalangeal joint (MP) Flexion / Extension Abduction / Adduction
Slide 8-

Bones of the Ankle Tibia Main weight bearing bone of LOWER LEG Forms medial malleolus Fibula Non-weight bearing Mainly muscle and ligament attachment Forms lateral malleolus Talus Main weight bearing bone of the ANKLE
Slide 9-

Lateral Ligaments of the Ankle Resist ankle inversion Anterior talofibular (ATF) Most commonly sprained Calcaneofibular (CF) Posterior talofibular (PTF)
Slide 10-

Medial Ankle Ligaments Deltoid Resists ankle eversion Low rate of injury

Foot and Ankle Injuries
Slide 43-

Ankle Sprain Cause: Excessive inversion or eversion of the ankle S/S: Point tenderness, swelling, discoloration, laxity, inability to walk or run properly (extent based on degree). TX: RICE, rehabilitation immediately (Grade III requires immobilization) Prevention: Strengthening exercises, proper shoes/ equipment
Slide 44-

1st Degree Ankle Sprain Mechanism (MX) Inversion and/or plantarflexion ATF most common sprained Occurs during contact or non – contact. Lateral Ankle Sprain
Slide 45-

S/S 1st degree Mild pain Pt – ATF Possible swelling Fast recovery to FWB and ROM No joint laxity Lateral Ankle Sprain
Slide 46-

2nd Degree Ankle Sprain MX Same as 1st degree, more severe. Involves the ATF, CF Possible growth plate involvement Most cases x-ray needed Lateral Ankle Sprain
