Results of bone scintigraphy in horses used for show jumping, hunting, or eventing: 141 cases (1988-1994).

The research article explores the effect of sports such as show jumping, hunting, and eventing on the bones of horses. The study identified specific anatomical patterns and clinical implications of increased radiopharmaceutical uptake in horses’ bones, revealing that such activities create unique stresses on the animals’ skeletal system.

Methodology

• The study was conducted retrospectively on 141 horses that were examined due to lameness issues.
• Researchers obtained information from a review of medical records, results of physical examinations, radiography, and bone scintigraphy.
• Bone scintigraphy was used to identify areas of the horses’ bones where there was increased uptake of radiopharmaceuticals.

Results

• In total, the researchers identified 834 areas of increased radiopharmaceutical uptake across the horses.
• In a subset of 78 horses in which the vertebral column was examined, 50 showed increased radiopharmaceutical uptake in the spinous processes.
• Scintigraphy performed on the proximal phalanges of forelimbs and hind limbs in 88 and 99 horses respectively revealed increased radiopharmaceutical uptake in the bone areas.
• Of 198 tarsal joints examined across 99 horses, 85 showed increased radiopharmaceutical uptake. A total of 155 scintigrams, out of the 374 available for review, showed increased radiopharmaceutical uptake as well.

Conclusions

• The study concluded that there is a strong correlation between the stress of jumping and distinctive patterns of increased radiopharmaceutical uptake seen in the horses. This suggests that horses used for sports like show jumping may be predisposed to developing specific orthopedic diseases, different from those seen in racehorses.
• Overall, out of 834 areas of increased radiopharmaceutical uptake, 214 were definitively associated with lameness. Therefore, the study provides evidence that certain sports activities significantly impact the skeletal health of horses, particularly those activities involving jumping.
