Retrospective study of 24 cases of septic calcaneal bursitis in the horse.

This study explores the clinical features, diagnostic findings, and outcomes of horses suffering from septic calcaneal bursitis, a condition arising from traumatic wounds affecting the calcaneal bursa. The research seeks to identify clinical signs and test results that can reliably indicate prognosis, and offers an analysis of the survival outcomes based on which anatomical structures are involved.

Research Methods

• The study was a retrospective examination of the medical records of 24 horses having traumatic wounds in the calcaneal bursae area.
• The researchers classified these horses into three categories based on the specific bursa involved and whether or not the tuber calcanei was affected.
• An in-depth documentation was made of the clinical observations, imaging diagnostic results, and surgical findings associated with each of these cases.
• To understand the difference between groups and outcomes, the researchers utilized Chi-squared, Fisher’s exact or Kruskal-Wallis tests as applicable.

Key Findings

• Specifically, it was found that wounds affecting only the subcutaneous bursa had an excellent survival outlook.
• Of those horses with wounds affecting the intertendinous calcaneal bursa, 75% survived.
• However, the survival prognosis was only fair to guarded with tuber calcanei involvement, noted as only 44% of horses with such cases surviving.
• Interestingly, unlike the findings of other studies dealing with septic synovial structures, the time lapse between the initial injury and medical referral didn’t influence the outcome in these cases.

Significance

• The research underscores the necessity of accurately identifying the involvement of calcaneal bursa(e) and/or tuber calcanei through the diagnosis of wounds on the tarsus plantar. This detection enables a more precise prognosis.
• Generally, the study found that cases involving damage to the tuber calcanei present a poorer prognosis compared to the cases that impact only the soft tissues in that body part.
• The research highlights the importance of precise anatomical identification of structures involved in wounds on the calcaneal bursa’s region.
• Methods such as radiography, ultrasonography, and synoviocentesis are crucial in diagnosing and treating wounds effectively and offering an accurate prognosis to the horse’s caretaker.
