Where is the stifle joint located?
The stifle joint (often simply stifle) is a complex joint in the hind limbs of quadruped mammals such as the sheep, horse or dog. It is the equivalent of the human knee and is often the largest synovial joint in the animal’s body. The stifle joint joins three bones: the femur, patella, and tibia.
How many joints does a stifle have?
The equine stifle consists of two joints: (1) the femoropatellar and (2) femorotibial.
What is a stifle joint on a cow?
When we talk about a stifled cow or bull, we refer to injury to ligaments surrounding the knee joint (the stifle joint) which is the first joint below the hips on the hind leg. An injury to this joint is common in dogs and in humans.
Which joint has the greatest range of motion?
Ball and Socket Joints
Ball and Socket Joints: These joints allow for the greatest range of motion.
What is the function of stifle?
The function of the stifle joint is to flex and extend the pelvic limb during ambulation, recumbency, and standing. The extensor muscles of the stifle attach to the patella and join in the fascial planes, merging with the patellar tendon and attaching to the tibial crest.
Is the stifle a hinge joint?
Since the stifle has primary motion in two planes, flexion and extension in the transverse plane, and internal and external rotation in the sagittal plane, the stifle is a complex hinge joint.
What type of joint is the stifle joint?
The stifle is a complex, condylar, synovial joint that allows motion in three planes. The complexity of the normal motion is directly related to the structure and functions of the anatomical components that form the joint.
What is string halt in cattle?
Stringhalt is a gait abnormality characterized by exaggerated upward flexion of the hindlimb that occurs at every stride at walk. The gait abnormality usually lessens at trot and is not evident at canter.
Which joint has the least range of motion?
Fibrous joints – the bones of fibrous joints are joined by fibrous tissue, such as the sutures in the skull or the pelvis. Fibrous joints allow no movement at all.
What is the weakest joint in the body?
Of the two areas where there are ball and socket joints, the shoulder is the weakest.
What movements can the stifle joint perform?
What is the difference between stringhalt and shivers?
Unlike Shivers, signs of stringhalt are often apparent when walking forward, with most or every stride appearing abnormal. Facial twitching and tail head elevation are absent. Signs of stringhalt are also observable at the trot, while Shivers horses trot normally.
What is Peg leg in cattle?
Peg-leg is a disease of cattle in North Queensland characterized by under- development, relative infertility, lameness, and various skeletal deformities. It is most common in pregnant and lactating females during the long dry winter.
Which joints have the most limited range of motion?
1. Fibrous joints – the bones of fibrous joints are joined by fibrous tissue, such as the sutures in the skull or the pelvis. Fibrous joints allow no movement at all.
What joint has the greatest range of motion?
What is horse EMND?
Equine motor neuron disease (EMND) typically occurs in older horses that have been vitamin E deficient for >18 months. EMND affects lower motor neurons, interfering with neurological input into muscles. Affected horses display muscle atrophy, weakness, and weight loss.
How do you tell if a heifer is a Freemartin?
Your veterinarian can examine the heifer at 3 to 6 months of age to see if the female tract is developing (some use a test tube to conduct the test). Vaginal length for normal heifers are usally 14 centimeters (5.5 inches) or greater. Freemartin vaginal length are typically 7 to 11 cm (2.8 to 4.3 inches).
The stifle joint is classified as a complex condylar synovial joint owing to the separation of its articular surfaces by intra-articular fibrocartilages—the menisci. Flexion-extension and rotation are the primary types of motion about the stifle. Bones of the Stifle Joint 118
What is the main articulation of the stifle?
The main articulation of the stifle is the femorotibial joint, which comprises the articulation between the thick, roller-like condyles of the femur and the flattened condyles of the tibia; this joint is the primary weight-bearing articulation.
What is the best book on stifle lameness in cattle?

How is a medial approach to the stifle joint performed?
A medial approach to the stifle joint is performed. The fracture fragment is reduced anatomically, and is temporarily stabilized to the condyle with pointed bone reduction forceps. A 2.0- or 2.7-mm lag screw is then inserted from the medial epicondyle across the fracture line into the lateral condyle.
