Where is the bursa located on a horse?
Usually, capped hock and capped elbow occur in acquired bursae, but some horses have naturally occurring subcutaneous calcaneal bursae. The bursae are located over the olecranon process and tuber calcaneus for the elbow and hock, respectively.
What is the calcaneus in horses?
The calcaneal (intertendinous bursa) lies between the tendons of the gastrocnemius and superficial digital flexor muscles proximal to the hock and extends on the plantar aspect of the calcaneus to the level of the distal tarsus.
What is navicular bursa in horses?
The navicular bursa is a synovial “sac” between the navicular bone and DDF tendon and serves to lubricate the tendon as it slides over the back of the navicular bone.
Where is the navicular bursa located?
The navicular bursa is a small synovial structure situated between the navicular bone and deep digital flexor tendon (DDFT) within the foot. It measures about two centimetres from top to bottom, and if not filled with excess fluid, is only a couple of millimetres thick.
Do horses have calcaneus?
The common calcaneal tendon in the horse is composed of the five fascicles coming from the two heads of the gastrocnemius muscle, the soleus muscle and from two calcaneal stripes derived from the muscles of the thigh (SZARO et al. 2011) .
What is bursa in horses?
A bursa is a small fluid-filled sac. The body contains lots of bursae – they minimise friction between tissues and help the gliding action of skin, muscle or tendons over bony surfaces. Direct trauma to these structures will result in painful swelling (bursitis).
How do you inject navicular bursa?
To inject the bursa, a 3.5-inch 18- to 20-gauge spinal needle is inserted midway between the bulbs of the heel, immediately proximal to the coronary band, aiming to the mark already placed on the lateral aspect of the hoof wall (Figure 3).
What are signs of navicular in horses?
Clinical signs of navicular disease include a short, choppy stride with lameness that worsens when the horse is worked in a circle, as when longeing. Frequent stumbling may occur at all gaits, even the walk, or when horses are asked to step over short obstacles such as ground poles.
Does calcaneus articulate with navicular?
The navicular bone is a keystone of the foot: it is part of the coxa pedis and articulates with the talus, first, second and third cuneiform, cuboid and calcaneus.
How do you inject navicular bursa on a horse?
What is the calcaneal tuber?
The calcaneal tuberclet is a bony eminence, often double, on the inferior surface of the calcaneus at the anterior end of the area for attachment of the long plantar ligament.
What is calcaneus anatomy?
The calcaneus is one of the 7 articulating bones that make up the tarsus. The calcaneus is located in the hindfoot with the talus and is the largest bone of the foot. It is commonly referred to as the heel.
Where is the calcaneal located?
foot
Located within the foot, the calcaneus is also known as the heel bone. It is situated in the back of the foot, just below the talus, tibia, and fibula bones of the lower leg.
How long do navicular bursa injections last?
Results: Following navicular bursa injection, 76 of 101 (75%) horses returned to their intended use for a mean of 9.66 months, and 35 (35%) were sound at follow-up.
Can a farrier cause navicular?
Farriery Causes The failure to achieve correct medial-lateral hoof balance may lead to coronary band shunting and undue strain on medial or lateral aspects of the navicular joint and navicular suspensory ligaments.
Can you still ride a horse with navicular?
Can a horse with navicular be ridden? Depending on the severity of the disease, it is possible to ride a horse with navicular, as long as your vet okays it. Pharmaceutical agents which can help alleviate pain and control inflammation such as Previcox and Tildren can be administered.
What attaches to the calcaneus?
The calcaneus is the largest bone in the foot. It projects posterior to the tibia and fibula and acts as a short lever for the calf muscles (gastrocnemius and soleus) which insert onto its posterior surface via the Achilles tendon.
