What are the fetlock joints?

Fetlock is a term used for the joint where the cannon bone, the proximal sesamoid bones, and the first phalanx (long pastern bone) meet. The pastern is the area between the hoof and the fetlock joint.

What 2 bones form the fetlock joint in a horse?

(a) The fetlock joint is formed by the junction of the third metacarpal bone (MC3) and the proximal phalanx bone (P1). The proximal sesamoid bones (PS) (both medial and lateral) are floating bones that are situated along the palmar aspect of the fetlock joint and are contained by the suspensory ligament (not shown).

How many bones are in the fetlock joint?

The fetlock joint is where the equine distal limb becomes more complex. The forces on the leg change angle especially at speed. There are four bones in this area: Cannon.

What is another name for the fetlock joint?

While sometimes the fetlock is colloquially referred to as an “ankle”, even by horse experts, that terminology is not correct. The fetlock is a metacarpophalangeal joint which corresponds to the human upper knuckle, such as that on the ball of the foot.

What is a dropped fetlock in a horse?

Abnormal sagging of the fetlock indicates weakness or loss of function of the suspensory apparatus of the hind limb. The most commonly implicated tendon associated with subtle dropping of the fetlock is the suspensory ligament.

Where is the fetlock joint on a horse?

A ‘horses fetlock’ is a name of a joint between the horses cannon bone and pastern bone and is ‘the ankle’ of a horse. At the rear of the fetlock joint is a small bone called the sesamoid.

What are three types of joints in a horse?

What are Joints?

• Synovial Joints: Synovial joints are the most common in the horse’s body.
• Fibrous Joints: Fibrous joints are less common; these joints do not allow for movement.

Can a horse survive a fractured fetlock?

As these fractures involve a large amount of energy at speed, with fractures comes severe trauma to the bones and the soft tissues surrounding them. Taking into account many factors, survival rates for fetlock arthrodesis after a breakdown injury is approximately 50- 60 per cent.

What causes a fractured fetlock?

They usually occur when the horse is exercising at a high speed due to overextension (hyperextension) of the fetlock joint. An affected horse will suddenly become lame and have swelling of the fetlock joint. Another type of fracture involves chips or loose fragments on the back of the long pastern bone.

What are the 5 ankle bones?

Ankle Anatomy

• the tibia, the larger and stronger of the two lower leg bones, which forms the inside part of the of the ankle.
• the fibula, the smaller bone of the lower leg, which forms the outside part of the ankle.
• the talus, a small bone between the tibia and fibula and the calcaneus, or heel bone.

How do you inject a fetlock joint?

The fetlock can be injected dorsally by inserting a needle toward the midline, lateral to the edge of the common digital extensor tendon just proximal to the dorsoproximal aspect of the proximal phalanx.

Can you fix a fractured fetlock?

Chip fractures or fragments within the fetlock joint are generally best removed surgically via arthroscopy. If the chips are within the joint they can cause damage to the cartilage surfaces, and promote inflammation which can lead to arthritis.

Why do horses wear fetlock boots?

Tendon and Fetlock Boots
Tendon boots protect the horse’s front legs from strikes from the hind hooves which can occur when landing a jump. In comparison, fetlock boots are used on the horse’s hind legs and just protect the fetlock from brushing injuries. There are many different styles available.
