Retrospective analysis of horses with ultrasound evaluation of the sacroiliac region and response to local corticosteroid injection: 42 cases.

The research article is a retrospective analysis study of horses with sacroiliac (SI) region pain and/or dysfunction that underwent local corticosteroid injections and ultrasound evaluations. The main focus of the study is if ultrasound findings, injection technique, or medications used in the injections can predict the recovery capacity of these horses.

Research Objectives and Methodology

• The primary objective of the research was to establish if ultrasound findings, injection techniques, or medications used in injections can predict a horse’s return to its previous function after experiencing pain or dysfunction in the sacroiliac region.
• Medical records of horses that underwent ultrasound examination and steroid injections were reviewed rigorously.
• A survey was conducted among clients to understand the performance level of the horses post-treatment.
• A logistic regression analysis technique was employed to ascertain if certain variables could predict the return of the horses to their levels of performance after undergoing treatment for sacroiliac region pain or dysfunction.

Key Findings

• Post-treatment, successful performance return to the same or advanced work level was recorded in 26 of the 42 horses, which represents 62% of the cases. A considerably lower proportion, 10% (4 out of 42), of the horses returned to work but at lower levels, while 28% (12 out of 42) of the horses failed to return to work at any level.
• The study observed that horses injected with methylprednisolone had a 4.2 times higher likelihood of returning to performance relative to those treated with triamcinolone.
• Notably, the study found out that factors assessed on ultrasound of the SI region were not inherent indicators of whether a horse would regain its performance after the sacroiliac region injection.

Implications and Conclusions

• The study casts crucial insights into the effectiveness of different corticosteroids in the treatment of sacroiliac region pain or dysfunction of horses. Specifically, it brings to light the superior potential of methylprednisolone relative to triamcinolone in inducing positive treatment outcomes.
• However, it also critically indicates that ultrasound diagnosis may not always be the best predictor of a positive treatment outcome for horses suffering from sacroiliac region pain and/or dysfunction.
