What Joint Is The Hock In A Horse?
The hock joints of your horse are located on the hind legs just above the cannon bones. They are equivalent to the human ankle.
What type of joint is the hock?
The hock joint is located in the hind limbs and is the equivalent of the human ankle joint. The hock joint is a complex joint comprising of a number of small bones articulating with the tibia (skin bone) and metatarsal bones (toes). Ligaments on the inside and outside part of the hock joint hold the bones together.
Is the hock joint a hinge joint?
For all practical purposes, the hock works as a hinge, moving by flexion and extension through one plane. Practically all of the movement occurs in the tibiotarsal joint.
Is the hock a synovial joint?
The highly specialized tissues of the synovial joint (such as the hock) come together to perform two main functions: Enable movement and transfer load from one bone to another.
How many joints in horses hock?
4 joints
The horse’s hock is made up of 10 bones and 4 joints supported by several ligaments. The largest joint is the tarso crural joint (TCJ), which forms the upper part of the hock and has a ball and socket mechanism. The TCJ has the greatest range of movement and is known as a high motion joint.
Is the hock a high motion joint?
Anatomy of the hock
The largest joint (the tarsocrural joint) forms the upper part of the hock and is known as a ‘high motion’ joint providing most of the hocks movement. The 3 lower joints (proximal intertarsal, distal intertarsal and tarsometatarsal) are ‘low motion’ joints and act as shock absorbers.
What are horse joints called?
Synovial Joints: Synovial joints are the most common in the horse’s body. They help with movement and come in different shapes, such as the ball and socket of the hip joint or the hinge joint of the elbow.
What joints are hinge?
Hinge joints, such as in the fingers, knees, elbows, and toes, allow only bending and straightening movements.
Which joint is hinge joint?
[3][4] The hinge joints of the body include the elbow, knee, interphalangeal (IP) joints of the hand and foot and the tibiotalar joint of the ankle.
What type of joint is a hinge?
Hinge joints are classified into the category of synovial joints. A synovial joint is a kind of joint which is found between two bones that move against each other, like joints of limbs. For example, shoulder, hip, elbow and knee.
What are the synovial joint parts?
Synovial joints share important structural components: subchondral bone, hyaline cartilage, a joint cavity, synovial lining, articular capsule, and supporting ligaments. Synovial joints serve a variety of functions and differ in configuration, permitting specific movements while restricting others.
What 3 joints in the hock are commonly injected?
Hocks
- Tarsocrural: main hock joint where most movement occurs.
- Proximal intertarsal (talocalcaneal– centroquartal): communicates with tarsocrural joint.
- Distal intertarsal (centrodistal): communicates with tarsometatarsal in a minority of horse (8% to 39%)
Are all joints synovial?
Synovial joints contain the following structures: Synovial cavity: all diarthroses have the characteristic space between the bones that is filled with synovial fluid.
Types.
| Name | Example | Description |
|---|---|---|
| Ball and socket joints “universal Joint” | shoulder (glenohumeral) and hip joints | These allow for all movements except gliding |
What does the hock joint do?
The hock is a joint in your horse’s hind leg. There are different types of joints throughout the body, and they all have varying degrees of movement and complexity. The hock is a major shock absorber, but also extends and flexes the hind leg. Its function is similar to the ankle joint in a human.
Is the hock a knee?
What is a Hock on a Dog? The canine hock joint, located on a dog’s back leg below the stifle (knee), corresponds to the ankle joint of a human.

Hock is the shortened form for the now obsolete word Hochheimer, after the German town of Hochheim that pioneered the use of the tall, slender bottle. The town’s name and its successful wines provided the inspiration for the name of the bottle shape.
What are the 3 types of joint movement?
The different types of movement that are permitted at each joint are described below.
- Flexion – bending a joint.
- Extension – straightening a joint.
- Abduction – movement away from the midline of the body.
What are the 4 joint movements?
The movement of synovial joints can be classified as one of four different types: gliding, angular, rotational, or special movement. Gliding movements occur as relatively flat bone surfaces move past each other. Angular movements are produced when the angle between the bones of a joint changes.
What does hock mean in horses?

What type of joint is the fetlock?
The fetlock is a hinge joint (ginglymus), allowing flexion and extension, but only allowing minimal rotation, adduction, or abduction.
