HealthWatch: Shock Wave Therapy Speeds Wound
Shock Wave Therapy Speeds Wound Healing
In their study, McClure and colleagues created a 4-cm and a 3-cm full-thickness wound on both front and rear cannon bones, respectively, of six healthy horses. The researchers treated one wound on each limb with ESWT, while the other limb was left as an untreated control. Researchers performed the ESWT weekly until they considered the wounds healed.
“While bacterial culture, area of epithelialization (skin growth), percent of wound contraction, and staining for growth factors were not different between the treated and untreated wounds, treated wounds had significantly shorter time for healing compared to the untreated wounds,” McClure said.
Specifically, wounds treated with ESWT took an average of 76 days to heal. Untreated wounds took an average of 90 days to heal.
While this study supports the use of ESWT for speeding wound healing, McClure suggested investigating the use of ESWT on dirtier wounds and on chronic wounds, as well as “the best times to perform ESWT, the best protocol to use, and whether ESWT should be combined with other therapies such as platelet-rich plasma or skin grafting.”

Shoes can be glued on directly or indirectly, Fraley explained. Glue is used just between the bottom of the foot and the shoe when gluing directly, while indirect gluing involves applying adhesive on tabs or cuffs around the outside of the hoof wall. Direct glue requires less shoe inventory, as you can use typical aluminum keg shoes, and the application is simple and atraumatic to the foot. However, he cautioned that applying glue to the bottom of the foot increases the risk of sealing in bacteria that can cause abscesses if care is not taken in foot preparation.
Cataracts in Foals
Congenital cataracts in newborn foals can be surgically removed, and the owner or manager should seek veterinary attention as soon as possible if he or she notices cataracts in a foal.
The surgical procedure is called phacoemulsification, which involves the same technology and equipment that’s used in human cataract surgery. Most foals spend about five to seven days in the hospital after surgery.
The most common postoperative problem is glaucoma. Cataract surgery will usually result in the horse’s being far-sighted (not able to see things up close as well as he sees things far away), but many horses go on to live productive lives after the procedure.
