Q

What are the anterior muscles of the foot?

Study These Flashcards
A

Extensor Hallucis Longus, Extensor Hallucis Brevis, Extensor Digitorum Longus, Extensor Digitorum Brevis. Tibialis Anterior

21
Q

What are the Extensor Hallucis Longus and Brevis mostly responsible for moving?

Study These Flashcards
A

The Great Big Toe.

22
Q

What are the Extensor Digitorum Longus and Brevis responsible for moving?

Study These Flashcards
A

The other 4 phalanges.

23
Q

What is the Tibialis Anterior responsible for moving?

Study These Flashcards
A

Inversion and Dorisflexion of the ankle.

24
Q

What are the medial muscles of the foot and what do they do?

Study These Flashcards
A

Tibialis Posterior, Flexor Hallicus Longus, and the Flexor Digitorum Longus, and all help each other in the plantar flexion of the foot.

25
What is the Tibialis Posterior responsible for moving?
Plantar Flexoin and Inversion.
26
What is the Flexor Hallicus Longus responsibe for?
Plantar flexion of the ankle and Flexion of the Big Toe.
27
What is the Flexor Digitorum Longus responsible for?
Plantar Flexion of the ankle and Flexion of the other 4 phalanges.
28
What are the posterior muslces of the ankle/ calf and what do they do?
Gastrocnemicus and Soleus, which are responsible for Plantar flexion of the foot.
29
What are the lateral muscle of the ankle and what are they responsible for?
Peroneus Longus and Peroneus Brevis, both are responsible for the eversion and plantar flexion of the ankle.
30
What are the 2 arches of the foot?
High arch (Supination) Low arch(Pronation)
31
What is flat foot known as?
Pes Planus
32
MOI: extreme inversion or eversion of the ankle. Patient is complaining of edema, ecchymosis, laxity, inabilty to walk or run.
Diagnosis: Ankle Sprain. Treatment: RICE, NSAID's, and PT. Prevention: stregthening and supporive shoes.
33
1st degree ankle sprain
ATF is most likely involved can go back to daily activity as tolerated.
34
2nd degree ankle sprain
ATF and CF are involved, X-Ray for a possible fracture of ankle, Short period of NWB on crutches.
35
3rd degree ankle sprain
ATF, PTF, and CF are involved. possible rupture of a ligament, X-ray for fractures, Extended NWB period.
36
MOI: Repetitive high impact activities like running or jumping. Patient will most likely complain of edema, crepitus, pain, pain with dorsiflexion, weak plantar flexion
Diagnosis: Achilles tendonitis. Treatment: RICE, NSIAD's, activity modifications, agressive stretching of the heel cord TID. Prevention: Achilles and Gastroc/Soleus Stretching three times a day.
37
MOI: Sudden forceful plantarflexion of the ankle with a chronically tight tendon. The patient will likely complain of feeling or hearing a pop during the injury, extreme pain, inability to plantarflex foot.
Diagnosis: Achilles Rupture. Treatment: Surgery or Immobilization. Prevention: Daily stretching and proper treatment of any tendonitis.
38
PE shows: PIPJ is flexed; MPJ and DIPJ are both hyperextended.
Hammer-Toe
39
Patient complains of pain, errythema, and edema near the nail bed.
Diagnosis: Ingrown Toe Nail. Treatment: Hot water soaking, antibiotics, matricectomy
40
Surgical Removal of a nail
Matricectomy
41
Patient complains of bony enlargement of the 1st metatarsal.
Diagnosis: Bunions aka HAV caused by wearing shoes that are not the right size.
42
What to look for in a visual Inspection of a typical foot exam.
Assymetry, Atrophy, Effusion, Edema, Ecchymosis.
43
What to look for in a palpation Inspection of a typical foot exam.
TTP over the (specific area)
44
what to look for in a neurological inspection of a typical foot exam.
Strength of separate muscle groups against resistance.
45
PE: Tests ligament instability, mainly used for testing of the ATF. However if injury is severe enough PTF of CF may trigger as well. Ankle is relaxed and slightly plantar flexed.
Anterior Drawer Test
46
Tests for lateral ankle instability, if + indicates a tear of ATF/CF ligaments.
Talar Tilt Test
47
Tests for Achilles rupture. Forced Achilles firing by manupulation of the gastrocnemicus and soleus complex by squeezing.
Thompson's Test.
