Study: Lasers Help Heal Equine Tendon And Ligament Injuries

High-intensity laser therapy (HILT) can be used to reduce inflammation in horses that have tendon and ligament injuries, a study from Poland has found.

Drs. Paulina Zielińska, Jakub Nicpoń, Zdzisław Kiełbowicz, Maria Soroko, Krzysztof Dudek and Daniel Zaborski used 26 Warmbloods with tendon and ligament injuries to see if laser therapy could provide anti-inflammatory relief. All horses were between 5 and 24 years old and were patients at the Faculty of Veterinary Medicine at the Wroclaw University of Environmental and Life Sciences.

All horses were assigned to a group that received 15 HILT treatments or a group that received no laser treatments. All horses had the same 40-day rehabilitation program, which included one 20-minute walk on hard ground each day, followed by cold water application on affected tendons or ligaments. The injuries were assessed before and after treatment, and ultrasound images were taken.

The team concluded that HILT provided swelling and pain relief; the ultrasound images showed a reduction in lesion size in the horses treated with laser therapy, as well. The researchers say that HILT can be used as a supportive treatment for horses that have tendon and ligament injuries, reducing swelling and lameness, and improving pain. They note, however, that there is no protocol for the number of HILT sessions, duration, energy dose or frequency of treatment for horses that have tendon and ligament injuries.

Does Suture Material Affect Surgery Speed?

Gelding operations are among the most-performed surgical procedures in the equine veterinary world. Though this surgery has been performed for many years, there is always room for potential improvement.

Drs. Ditte Marie Top Adler, Stine Østergaard, Elin Jørgensen and Stine Jacobsen, of the University of Copenhagen, wanted to compare a new, barbed suture martial to traditional suture material that requires the surgeon to make multiple knots to keep the stitches in place. The barbed suture material has tiny barbs on the surface that lock the material in place, eliminating the need for knots. Manufacturers claim the barbs make the material more secure and increase the speed at which the castration can be performed.

The research team used 45 horses that were brought to The Large Animal Teaching Hospital at the University of Copenhagen for inguinal castrations; 24 of the horses were sutured with smooth material and 21 were sutured with the barbed material. The scientists then evaluated any complications while the horse was in and out of the hospital. They also compared how long it took the veterinarian to close the surgical wounds.

There were minor short-term complications; swelling was noted in 29 percent of the stallions that had the barbed suture material and in 33 percent of the horses that had the smooth suture material. Three horses required follow-up care for castration complications. One had scrotal swelling (barbed suture material had been used); one had a weeping wound (smooth suture material had been used); and one had the wound reopen (smooth suture material had been used).

Veterinarians using the barbed suture material were able to close the wound six minutes faster than using smooth suture material.

Though the cost of barbed suture material is higher, it reduced surgery time by 40 percent and it did not result in increased post-op complications.
