Q

What forms the ankle (mortise) joint?

A

Tibia and fibula (medial/lateral malleoli)

17
Q

Why is the mortise joint not fully open on an AP projection?

A

Distal fibula is 1/2” more posterior than distal tibia, 15-20 deg from MCP

18
Q

What is found opposite the sustentaculum tali?

A

Peroneal trochlea (trochlear process)

19
Q

What is osteoarthritis?

A

Loss of joint cartilage, affects predominantly the weightbearing joints
-narrowing of joint space, thinning of articular cartilage, developments of osteophytes (spurs), irregular

20
Q

What type of joint is the ankle joint?

A

A synovial joint of the sellar type

21
Q

What pass through the calcaneal sulcus and sinus tarsi?

22
Q

What can increase the ankle joint space?

A

“Sprained ankle” stretched or torn collateral ligaments or torn muscle tendons

23
Q

What is a Salter-harris fracture?

A

Fracture between the epiphysis and metaphysis

24
Q

What can be performed to evaluate the stability of the joint space?

A

AP stress views

25
Where is the transverse arch located?
Plantar surface of foot, distal tarsals
26
What is found on either side of the calcaneal tuberosity?

31
What type of synovial joints are IP joints?
- Ginglymus/hinge | - flexion and extension
32
What type of synovial joints are TMT joints?
- Plane/gliding | - limited gliding movement
33
What type of synovial joints are IT joints?
- plane/gliding | - inversion/eversion (gliding and rotation)
34
What type of synovial joint is the ankle joint?
- sellar/saddle - dorsiflexion and plantarflexion only - side to side only occurs with stretched or torn ligaments
