Post.talofibular
What is the syndesmosis in the ankle?
Connection btw
tib/fib by Inter-
Osseous Ligament
What is the medial ligament in the ankle?
Deltoid ligament
What history questions need to be asked for ankle injuries?
When and What happened? Which way did it bend/twist? Able to ambulate? Swelling? Previous injury and when?
What is the most common ankle injury? How is it caused?
- Lateral ligament sprains
- Plantar flexion and inversion
- > 40% can lead to chronic problems
What is another name for a high ankle sprain? What is the prevalence and how is it caused?
- Syndesmotic sprains
- 10%
- Dorsi-flexion and/or eversion, rotational injury
What is the prevalence of medial ankle sprains and how is it caused?
- 5%
2. Eversion
What needs to be assessed for an ankle injury pt?
1. AROM & PROM A. Inversion and eversion B. Plantar and Dorsiflexion 2. Strength A. Not very helpful following acute injury 3. Sensation 4. Vascular 5. Special testing
What are the normal ranges of motion for plantar flexion, dorsiflexion, inversion, and eversion of the heel?
Plantar Flexion: 50 degrees
Dorsiflexion: 20 degrees
Inversion of heel: 35 degrees
Eversion of heel: 15 degrees
What does the anterior drawer test of the ankle assess? How is it performed?
- Checks ATFL
2. Foot neutral pos, plantar flex 10 deg,stablize distal leg & pull heel anteriorly
What is an abnormal anterior drawer ankle test?
Abnormal Translation is 5-10 mm, or 3 mm > than other side
What does the Talar tilt test of the ankle assess? How is it performed?
- Checks the calcaneo-fibular ligament (CFL) and ATFL
- Ankle/foot unsupported in 10-20 deg of plantar flexion, stab. medial distal leg & apply inversion force slowly to hindfoot
What is an abnormal talar tilt ankle test?
Laxity (lack of endpoint)
-Most nl ankles have a tilt of approx 5 deg or<
What does the Thompson test of the ankle assess? How is it performed?
- Checks integrity of Achilles tendon
- Patient prone feet hanging off table
- Squeeze gastrocnemius muscle
What is an normal Thompson ankle test?
Should cause plantar flexion of foot if tendon is intact
What is a grade I ankle sprain?
Stretching, small tears
What is a grade II ankle sprain?
large but incomplete tear
What is a grade III ankle sprain?
Complete tear
What are the dx tests for ankle injuries?
X-ray
Lateral
Mortise
PA
What is the tx for ankle injuries?
1. RICE: A. Rest B. Ice, Compression, and Elevation 2. Aircast 3. Crutches 4. NSAID’s
Define sesamoid bones
Most bones in the human body are connected to each other at joints.
There are a few bones that are not connected to anyother bone.
Instead, they are connected only to tendons or are embedded in muscle. These are the sesamoids.
A good example is the kneecap (patella), whichis the largest sesamoid.
Two other very small sesamoids, eachabout the size of a kernel of corn,are found in the underside of the forefoot near the big toe, one on the outer side of the foot and the other closer to the middle of the foot.
