Equine diagnostic imaging

Metacarpophalangeal joint is also known as the

Fetlock joint

What makes up the fetlock joint

Cannon, long pastern, and proximal sesamoid bones

Ligaments that make up the fetlock joint

collateral, palmar sesamoidean, short sesamoidean, and suspensory ligament

Tendons that make up the fetlock joint

common digital extensor and superficial and deep digital flexor tendons

A joint capsule surrounds the joint

Articular capsule

A boiled pad on the distal aspect of the <cIII that cushions the joint

Synovial pad

Signs the fetlock joint is in pain

lameness, swelling, heat, and pain

The proximal interphalangeal joint is also known as the

pastern joint

What does the pastern joint do

allows the horse to flex and extend it’s food

What time of joint is the pastern joint 

hinge joint

What ligaments support the pastern joint

Collateral, abaxial, and axial ligaments

Osteoarthritis is known as 

high ringbone

Common disorders with the pastern joint

osteoarthritis, fractures, luxation, and subluxation

Distal interphalangeal joint is also known as the 

Coffin joint 

The coffin bone allows for 

flexion and extension of the foot

The coffin joint is made of the

distal and proximal phalanx

Lamenitis can cause the coffin bone to

rotate and damage the coffin joint

Small fluid-filled sac in horse’s feet that cushions the navicular bone

Navicular bursa

the Navicular nurse does what 

lubricates the deep digital flexor tendon (DDFT)

The navicular bursa is located between

the navicular bone and deep digital flexor tendon

The medial and palmar nerves run between the

suspensory ligament and the deep digital flexor tendon

Main artery supply to the fetlock and digit

Median palmar artery

Radiographs in horses are used for

lameness, dental issues and sinus issues

4 positions for the coffin bone

LM, DP, DLPMO/DMPLO, and skyline

Positioning angles for the fetlock

LM, DP, and DLPMO/DMPLO

Nuclear scintigraphy is a 

bone scan

Bone scan is used to elevate

lameness and poor performance

CT stands for 

Computed tomography

MRI stands for

magnetic resonance imaging

What is the purpose of the white line of a hoof

joins the sole to the inner wall of the hoof, seals off the border

What is the purpose of the frog of a hoof

aids in shock absorption

Purpose of the sole of a hoof

offers a protective surface

Purpose of the bar of the hoof

controls the movement of the back of the hoof

Thin, waxy layer of tissue that covers the outer surface of a horse’s hoof wall
