Scintigraphic, radiographic, and thermographic appearance of the metacarpal and metatarsal regions of adult healthy horses treated with nonfocused extracorporeal shock wave therapy–a pilot study.

This research article explores the potential impacts of nonfocused extracorporeal shock wave therapy (ESWT) on horse bone health. After applying the treatment to six adult horses, no noticeable effects were discovered using thermal, scintigraphic, or radiographic examination techniques.

Introduction

• The article presents a study on nonfocused extracorporeal shock wave therapy (ESWT), an often-used treatment protocol in veterinary practice, and its impact on adult horse bone health.
• ESWT is known for its use in treating musculoskeletal issues in horses. This non-invasive method utilizes pressure waves to stimulate healing.

Methodology

• The study involved six untrained adult horses, which were given a series of four nonfocused ESWT treatments at two-week intervals.
• The regions targeted by the treatment were in the metacarpal and metatarsal, and researchers examined the impacts using various methods.

Techniques Used to Monitor Effects

• The techniques used to monitor the effects of the ESWT include scintigraphy, radiography, and thermography.
• Scintigraphy, a diagnostic technique, was performed at two-week intervals to measure the bone’s radiopharmaceutical uptake – this can help detect any bone remodeling or abnormalities.
• Radiography was conducted before and after the study, allowing a comparison of the bone’s structure before and after treatment.
• Thermography was performed daily to detect any changes in heat production in the treated regions. An increase in heat can indicate inflammation or changes in blood flow.

Results

• The investigation found no measureable changes on the horses’ bones across all three examinations.
• There was no significant bone remodeling detected, implying that the ESWT treatment on healthy horses did not cause a notable impact on the metacarpal and metatarsal bone health.

Conclusion

• The study concludes that nonfocused ESWT, when applied to the metacarpal and metatarsal bones of healthy, untrained adult horses, does not result in dominant evidence of bone remodeling detectable by conventional clinical assessment techniques.
• This finding can help guide veterinary treatment choice, reassuring practitioners that such treatment can be applied without causing detectable negative alterations to the underlying bone health.
