Exam Q: Ankle region Flashcards
Name the bones
Tibia and fibula
Choose one bone. Classify the bone according to its shape. Why is it classified this way?
Tibia = long.
Shaft and two extremities
Side the bone. WHy is it from the … side?
Right/left.
Distal end-lateral = Malleolus
Med border = sharp interosseous border
Prox end = facet for articulation with lat condyle of tib
Name the joints tibia and fibula participates in?
Tibia = knee jt + T-F joints, ankle joint Fibula = T-F joints + ankle joints
On the bone, identify the major bony features on the shaft and distal end of tibia
Soleal line, ant border, interosseous border, medial malleolus, fibular notch
Describe and identify the location of anatomical structure that contribute ot the stability of ankle jt
Eg:
Lig: MCL (4), LCL (3)
M: ant, lat, post comp of leg
With reference to the ankle jt - identify the type of joint and the articular surfaces
Modified HINGE jt.
Inf surface of distal tibia, med malleolus, lat malleolus, sup surface of talus + ??
On the model, palpate major bony features around ankle region
Med + lat malleolus,
sup surface of talus,
head of talus, calcaneus,
tub of navicular
Name and identify on the model the location of major blood vessels and nerves that traverse ankle region
Ant: Ant tibial art + dorsalis pedis art, deep fibular n
Med: Post tibial art, tibial n
Lat: Superficial fibular n
Name + demonstate movements (inc plane and axis) that occur at ankle jt.
Use model
Dorsi- / Plantarflexion: Sagittal plane about frontal axis
Select 2 movements that occur at the ankle or subtalar jt:
For each movement:
- Name the movement
- name the major M group involved in movement
- On the model, identify location of the M group and palpate M belly and tendon of insertion (!)
- Demonstrate major M group working either con or eccentrically
Eg: DORSIFLEXION
- dorsiflexors of ankle (TA main one)
- ant comp of leg
- exercise??
PLANTARFLEXION:
- plantarflexors of ankle
- Post comp of leg
- exercise?
Position gastrocnemius in its lengthened position
Position soleus in its lengthened position
Discuss reasons for choice of positions.
Gastroc vs soleus.
Principle of passive insufficiency?!
WHAT?? :-(
On the model, palpate the LCL of the ankel jt. What movement(s) may be limited by LCL? Why?
LCL = 3 parts (ant T-F, C-F, post T-F)
Inversion. Under tension.limiting structures.
