Plain-English summary

This study looked at four horses with a condition called fibrotic myopathy, which affects the semitendinosus muscle and causes problems with their movement. Two of these horses had been experiencing this issue since they were born. The researchers compared a surgical procedure called semitendinosus tenotomy with a more traditional surgery called partial myotenectomy, which also treats this condition. The results showed that both surgeries helped the horses regain their ability to perform athletic activities, but the tenotomy procedure had a better cosmetic outcome. Overall, the treatment appeared to work well for these horses.

Abstract

The medical records and follow-up data for 4 horses with fibrotic myopathy of the semitendinosus muscle treated by semitendinosus tenotomy were reviewed. The gait deficit for each of the 4 horses was typical of fibrotic myopathy. Two of the horses had the gait deficit since birth. The efficacy of semitendinosus tenotomy was compared with the traditional treatment of partial myotenectomy of the affected muscle. The functional results in the 4 horses appeared to be equal to partial myotenectomy in returning the horses to athletic function and, compared with what has been reported, was cosmetically superior.
