Transcript Foot Ankle Lower Legx

Ankle, Foot, & Lower
leg
introduction
• 15% of all sports injuries
involve the ankle.
• More than 20,000 ankle
sprains occur in the US
everyday!
• Most common reason for
ER visits.
• The foot stabilizes and
supports the rest of our
body during walking,
running, and jumping.
• There are 26 bones is the
foot.
• 7 Tarsals, 5 Metatarsals, 14
Phalanges
Range of motion
• Dorsiflexion
• Plantarflexion
• Inversion
• Eversion
• Flexion (toes)
• Extension (toes)
• Pronation (combined motions of calcaneal eversion, foot abduction
and dorsiflexion)
• Supination (combined motions of calcaneal inversion, foot adduction,
and plantarflexion)
Bony anatomy
• Tibia
• Fibula
• Talus
• Calcaneus
• Navicular
• Cuneiforms (1-3)
• Cuboid
• Metatarsals (1-5)
• Phalanges (1-5)
• Lateral/Medial Malleolus
Arches of the foot
• Transverse Arch – composed of the cuneiforms, the
cuboid, and the 5th metatarsal.
Arches of the foot
• Lateral Longitudinal Arch – composed of the
calcaneus, talus, cuboid, and 4th and 5th metatarsals.
Arches of the foot
• Medial Longitudinal Arch – the highest of the three
arches; composed of the calcaneus, talus, navicular,
cuneiforms, and the first three metatarsals.
ligaments
• Reminder - Ligaments connect bone to bone!
• Lateral:
• Anterior Talofibular
• Calcaneofibular
• Posterior Talofibular
• Anterior Tibiofibular
• Medial:
• Deltoid ligaments
Main Joints of the
ankle
• Reminder – Joints are where two bones articulate or meet!
① Talocrural Joint = Formed by the Tibia, Fibula, and Talus (hinge joint
allowing plantar flexion and dorsi flexion)
② Subtalar Joint = Formed by the Talus and Calcaneus (eversion, inversion)

Anatomy Summary
• The foot has 3 arches – transverse,
medial longitudinal, lateral
longitudinal.
• The foot has 26 bones – 7 tarsals, 5
metatarsals, and 14 phalanges.
• The ankle joint is made up of the
talocrural and subtalar joint.
• There are 5 main ligaments in the
ankle – anterior talofibular,
anterior tibiofibular,
calcaneofibular, posterior
talofibular, and the deltoids.

Ankle sprains
• One of the most common injuries to
the body.
• Lateral Sprain - the most common type
of sprain.
• More than 80% of ankle sprains are
lateral.
• Involves injury to the lateral ligaments.
• The anterior talofibular is the most
commonly sprained ligament because it
is the first lateral ligament that is
stressed during inversion.
• Eversion Sprain – less common.
• Involves injury to the deltoid ligaments.
Ankle sprains
• Grade 1 (Mild): 1 or
more ligaments are
stretched.
• Grade 2 (Moderate): 1
or more ligaments are
partially torn.
• Grade 3 (Severe): 1 or
more ligaments are
completely
ruptured/torn.
Ankle sprains
• MOI (Mechanism of Injury):
• Lateral Sprain = Excessive inversion
• Eversion Sprain = Excessive eversion
• S&S:
• Mild – mild discomfort, point tenderness, little or no swelling, no joint
laxity
• Moderate – pain, swelling, point tenderness, loss of function, slight
joint laxity.
• Severe – pain, loss of function, point tenderness, rapid swelling, joint
laxity.
• Special Tests: Anterior Drawer, Talar Tilt, Kleiger Test

Ankle sprain
treatment
• Immediate Treatment:
• Protect – Splinting, taping, or bracing
• Rest – Avoid activity, crutches if needed
• Ice – 20 minute applications
• Compression Wrap – controls swelling (horseshoe method)
• Elevation – above the heart
• Follow-Up Treatment:
• Rehabilitation - ROM exercises, stretching, and strengthening

Syndesmosis sprain
• AKA High Ankle Sprain
• Injury to the Anterior Tibiofibular Ligament
• https://www.youtube.com/watch?v=-gKxAUyKF3c
Syndesmosis sprain
• MOI: Forceful dorsiflexion and external rotation.
• S&S:
• S&S are consistent with other sprain with the exception of
• Pain and point tenderness between the distal tibia and fibula.
• Special Test: Kleiger’s Test
• Much longer healing process

Syndesmosis sprain
Achilles tendonitis
• The achilles tendon attaches the
gastrocnemius and the soleus muscles to
the calcaneus.
• The gastrocnemius/soleus muscles give us
the ability to plantarflex.
• Tendonitis = inflammation of the tendon.
• Overpronation makes an athlete more at
risk.
• MOI: Chronic injury due to excessive
stress.
• S&S: Symptoms will develop gradually.
Pain and discomfort that becomes worse
over time, possible crepitus. In extreme
cases, the tendon will appear thickened.
Achilles tendonitis
treatment
• Prevention!!
• Maintaining flexibility of the
achilles tendon will prevent
injury.
• Solve biomechanical problems
such as overpronation.
• Refer to a podiatrist (foot
doctor).
• Rest
• Ice
• Anti-inflammatory medication
Achilles tendon
rupture
• Predisposing factors: Poor conditioning, decreased ROM of the
achilles tendon, athletes over 30 years old, previous history (hx) of
achilles tendonitis.
• MOI: Forceful contraction such as a sudden push off or sudden force
applied to a dorsiflexed foot.
• S&S:
• Will feel and hear a “pop”
• Visible defect
• Inability to stand on toes
• Excessive passive dorsiflexion.
• Special Test: Thompson Test
• *Surgery is required to reattach the tendon*

Great toe sprain
(aka turf toe)
• Great Toe = 1st Phalange
• The great toe is important for
balance, movement, and speed.
• “Turf Toe” = a sprain to the
ligaments supporting the great
toe.
• MOI: Hyperextension of the
first metatarsophalangeal joint.
• S&S: Pain, point tenderness,
swelling, ecchymosis, limited
mobility.

• Treatment:
• PRICE Method
• When normal function is
restored and the athlete is
ready to RTP, use taping
techniques to provide
support/limit movement.

Plantar fascitis
• Plantar Fascia = a wide, nonelastic
ligamentous tissue that extends from the
anterior portion of the calcaneus to the
heads of the metatarsals.
• Supports the longitudinal arches of the
foot.
Plantar fascitis
• MOI: Chronic irritation of the plantar fascia
causing inflammation. Examples…..
• Running on hard surfaces
• Unsupportive footwear
• Repetitive running and jumping sports
• Tight achilles tendon
• S&S: Pain and point tenderness on the bottom of
the foot near the heel.
Plantar fascitis
treatment
• Correcting training errors
• Evaluate athlete’s shoes and activity
levels
• Wear shoes with more arch support to
help decrease stress
• Ice
• Massage
• Taping techniques for arch support
• Stretching

Medial tibial stress
syndrome (Mtss)
• AKA Shin Splints!
• Chronic/Overuse
injury
• Inflammation of the
periosteum (outer layer
of bone).
• Usually occurs on the
distal third of the
medial tibial border.
• Typical in
runners/jumpers.
Medial tibial stress
syndrome (Mtss)
• Causes:
• Tightness of the
gastrocnemius/soleus.
• Running on hard or
uneven surfaces.
• Poor footwear.
• Excessive pronation.
• Recent changes in
running distances, speed,
form, stretching,
footwear, or running
surface.
Medial tibial stress
syndrome (Mtss)
• S&S:
• Dull pain that begins at any point in the workout; occasionally
may be sharp and penetrating.
• Pain occurs along the medial border of the tibia in a 3-6 cm area;
usually in the distal third.
• Pain is relieved with rest, but may recur hours after activity stops.
• Pain aggravated by plantar flexion.
• In later stages, pain will be present before, during, and after
activity and may restrict performance.
Medial tibial stress
syndrome (Mtss)
• Treatment:
• 5-7 days of rest to relieve acute symptoms.
• Cryotherapy (Ice, Whirlpool, Ice massage)
• NSAIDS (Anti-inflammatory medication)
• Increase flexibility/strength in anterior and
posterior musculature.
• Analysis of running mechanics, foot
alignment, running surface, and footwear.
• If pain persists R/O stress fractures.
Evaluation of the
foot/ankle/ lower
leg injuries
H.O.P.S
• H.O.P.S.
• History – How did it happen (MOI), location
of pain, previous hx.?
• Observation – What do you see/observe?
• Palpation – Palpate for crepitus, spasm, point
tenderness, warmth, etc.
• Special Tests – Assess ROM, Manual Muscle
Tests (MMT) and Special tests.

Special tests
①Assess ROM in all directions
②MMT’s (Manual Muscle Tests)
③Special Tests:
ROM
• Ask the athlete to perform the appropriate ROM depending
on the joint to the best of their ability (Example: Ankle =
plantarflexion, dorsiflexion, inversion, eversion)
• Check both extremities simultaneously, noting any
differences.
• The motion should be smooth and painless.
• Limited ROM on one side indicates potential injury or
deformity.
Manual muscle tests
MMT = manually testing an athlete’s
strength to note any abnormalities due to
injury.
Compare the strength between the
involved and uninvolved extremity to
note any differences.
Weakness on one side indications
potential injury or deformity.
