Q

Why there is greater ankle stability when we are in dorsiflexion?

A

Talus is wider anteriorly than it is posteriorly and there is less movement at the ankle motus.

Q

What is a pes cavus foot and why is it bad?

16
Q

What are some mechanisms for leg cramps/spasms?

A
  • Electrolyte imbalance
  • Dehydration
  • Improper neuromuscular firing.
17
Q

What bone is most likely to get a stress fracture?

18
Q

What is the common name of medial tibial stress syndrome?

A

Shin splits - pain is not in a single spot but lower distal 1/3 of tibia.

19
Q

What causes a gastrocnemius strain? What is the common name?

A

Forceful extensio of the knee when its in dorisflexion.

Common name - tennis leg.

20
Q

What makes up the deltoid ligament in the ankle?

A

Anterior Tibiotalar Ligament, Tibiocalcaneal Ligament, Posterior Tibiotalar Ligament, and Tibionavicular Ligament

21
Q

What causes avulsion on the 5th metatarsal?

A

When is the fibularis brevis contracts to control inversion and pulls so hard that a piece of bone comes off.

22
Q

Why are Jones fractures problematic?

A

Doesn’t heal well because of poor blood supply and typically people will get a screw up in to hold one end into another.

23
Q

What is calcaniofibular sprain? What is considered a positive test?

A

Pure inversion mechanism - motion more than 10 degrees.

24
Q

What is a characteristic of a high ankle sprain injury?

A

Gapping at the ankle motus.

25
Why does down hill running cause achilles tendon disorders?
Lots of force to absorb.
26
Mechanism of injury for achilles tendon disorders. What does the injury look like.
Tight muscle/Tendon complex Bony malalignment of foot. Change in shoes or running surface Increase in workload. Achilles got thicker due to cumulative microtrauma.
27
What is the role of the fibularis retinaculum?
Wraps drown and around the lateral malleolus.
28
Where do you feel pain in fibularis tendonitis, anterior tibialis and posterior tibialis tendonitis?
F- pain behind lateral malleolus AT - pain at front of ankle or medial midfoot. PT - posterior and distal of medial malleolus.
29
What is the MOI for plantar fasciitis?
Training errors, training surfaces, and footwear. Arch shape, excessive pronation, tight or weak calf muscles.
30
Why does a donut pad help with heel bruises?
Force is distributed around painful area.
31
What is good to remember from "pump bumps"?
Not achilles tendon issue but just from new shoes.
32
Describe retrocalcaneal bursitis?
It is quite common when the tendon is thin and the bursae will swell and pop out on either side of the calcaneal tendon.
33
What is truf toe? How does it occur?
Sprain at the first MCP joint from hyperextension at the big toe. Hard to tape because too much flexion is not functional.
