Case of the week: A 15-year-old gelded miniature pony presented with an inability to bear weight on its right hind leg grade 5/5 lameness on the AAEP Lameness scale).

Examination revealed a laterally displaced right hind fetlock that was painful on palpation. Radiographs were taken to help guide a diagnosis of fetlock luxation and to rule out fracture.

After diagnosis was made, the limb was stabilized. First, the fetlock was replaced with gentle traction; then, a makeshift splint was applied on site.

Pain was managed with phenylbutazone over night until the pony could be transported to the clinic for cast placement. Casting is a critical step in immobilizing the joint space, allowing for tendons and ligaments to return to normal tension. The Cast will be in place for at least one month.
Slow return to physical activity is recommended to reduce the chance for re-injury once cast is removed.

Case of the week: Exuberant Granulation Tissue: “Proud Flesh”

A 7-year-old Tennessee Walking horse broodmare presented after having her leg caught in a fence. The 10cm x 4cm laceration filled in very quickly with exuberant granulation tissue, or more commonly termed, ‘proud flesh.’

The production of granulation tissue is a vital part of the healing process, as it fills defects overlying deep and superficial structures within the body. However, horses are prone to having an uncontrolled production of this tissue. This is termed Exuberant Granulation Tissue (EGT), or “proud flesh”. This is a problem, as EGT will not allow normal epithelization (skin healing) to occur, and will leave the horse and owner fighting with a fleshy, vascular, red and bumpy eyesore. Treatment is dependent on the amount EGT, but typically requires the tissue be debrided (cut off) just beneath the surface of the skin. This gives normal epithelial cells the ability to grow from the perimeter of the defect inwards. It can take multiple series of debridement and the aid of anti-granulation tissue products to have satisfactory results.
