Surgery May Improve Thoroughbred Yearling’s Racing Career

A new study found that carpal osteochondral fragments (COF) may impair the performance and purse of a Thoroughbred yearling. However, arthroscopic COF removal may improve a Thoroughbred’s yearling sales and racing performance.

In a retrospective observational study, the researchers reviewed clinical records from 2015 to 2018 of 26 Thoroughbred yearlings that had surgery for COF and 20 who were conservatively treated. Another group of 138 sire- and year-matched siblings without radiographic evidence of COF served as controls.

They found that radiographic evidence of COF was associated with significantly lower sales prices and total winnings, regardless of how the horses were treated. However, the horses in the surgical group were more likely to achieve a racing career than those treated conservatively (OR: 6.2, P=0.03, 95% CI: 0.987-69.690).

“When compared with control horses, conservative management of COF was overall associated with significantly poorer sales and racing performances,” the researchers wrote.

The data indicated “that COF can impair a Thoroughbred’s racing and especially sales performance,” they concluded.

The study had several limitations, including a small sample size. More investigation into outcomes for COF are warranted, they said. MeV
