Nerve blocks are performed in a step-wise fashion, beginning at the most distal (lower) part of the limb and moving upward. This is due to the fact that blocking a nerve higher up will desensitize everything it innervates distal to the blocking location.
Horses are at risk of re-injury of the fracture site, especially when trying to rise after lying down, or when recovering from anesthesia following fracture repair. Forced recumbency is not an option for horses, making healing more difficult. Weight bearing on a single front or hind limb increases the likelihood of support limb laminitis.
Curb as a visible blemish is an easy diagnosis, as swelling in the distal lateral hock region is, by definition, curb. However, ultrasound is an essential tool in the diagnosis and in establishing a treatment plan. Diagnostic anesthesia (local or nerve blocks) can be helpful, but is not perfectly specific in this area.
A flexion test is a preliminary veterinary procedure performed on a horse, generally during a prepurchase or a lameness exam. The purpose is to accentuate any pain that may be associated with a joint or soft-tissue structure, allowing the practitioner to localize a lameness to a specific area, or to alert a practitioner to the presence of sub-clinical disease that may be present during a pre ...
Radiograph of a horse hoof showing rotation of the coffin bone and evidence of sinking, a condition often associated with laminitis. The annotation P2 stands for the middle phalanx, or pastern bone, and P3 denotes the distal phalanx, or coffin bone. The yellow lines mark the distance between the top and bottom part of the coffin bone relative ...
The cauda equina (from Latin tail of horse) is a bundle of spinal nerves and spinal nerve rootlets, consisting of the second through fifth lumbar nerve pairs, the first through fifth sacral nerve pairs, and the coccygeal nerve, all of which arise from the lumbar enlargement and the conus medullaris of the spinal cord.
Back pain in a horse may be related to movement in an unnatural and stressed position, not unlike those that cause back pain in humans. Back pain in a horse may be caused for a variety of reasons. Saddle fit, poor riding technique, lack of conditioning, overwork, accidents, or lameness can all contribute to back pain. A saddle that is not ...
This allows great mobility in the front limb, and is partially responsible for the horse's ability to fold his legs up when jumping. Although the hindlimb supports only about 40% of the weight of the animal, it creates most of the forward movement of the horse, and is stabilized through attachments to the spine.
