Tib/Fib and the talus

What is the ankle joint made of?

Lateral malleolus

the expanded distal end of the slender fibula which extends well down alongside the talus

Medial malleolus

the medial elongated process of the tibia that extends down alongside the media talus

Mortise

the inferior portions of the tibia and fibula form a deep "socket" or three-sided opening

Mortise position

a 15 degree internally rotated AP oblique projection of the ankle

Anterior tubercle

an expanded process at the distal anterior and lateral tibia that has been shown to articulate with the superolateral talus

Tibial plafond

Tibia

one of the larger bones of the body , the weight bearing bone of the lower leg

Medial and lateral condyles

2 large processes that make up the medial and lateral aspects of the proximal tibia

Intercondyler eminence

2 small pointed prominences that are located on the superior surface of the tibial head between the 2 conyles

Tibial plateau

articulates with the femur

Tibial tuberosity

rough-textured prominence locates on the mid anterior surface of the tibia just distal to the condyles

Arthrography

looks for the knee

CT

looks for the lower limbs and soft tissue

MRI

looking at the knee

Bone densitometry

loss of bone in older patients

nuclear medicine

radioisotopes injected into the bloodstream, looks for pathologys

supine and knees flexed
