Treatment of supraspinous bursitis by use of debridement in standing horses: 10 cases (1968-1999).

This research studies the effectiveness of a surgical procedure called debridement for treating supraspinous bursitis, a condition causing pain and swelling in horses, evaluating both the immediate surgical outcome and longer-term results.

Objectives and Methodology

• The aim of the study was to assess the effectiveness of debridement, a surgical process of removing damaged or infected tissue, for treating supraspinous bursitis (an inflammatory condition affecting a specific bursa in the horse’s back) in horses.
• The researchers carried out a retrospective study, examining existing records and data to gather information.
• The study involved medical records of 10 horses exhibiting clinical signs of supraspinous bursitis. These records were studied for various data like anamnesis (medical history), physical examination results, radiographic examination results, results of microbial culture of the supraspinous bursa tissue or exudate, and the type of antimicrobial and anti-inflammatory therapies used. The surgical technique used, any complications arising from the surgery, and the results of the histologic examination of the nuchal ligament and the bursal tissue which were excised were alsorecorded.
• Additional information was obtained through telephone follow-ups with the horse owners, their trainers, or referring veterinarians.

Results

• The study results showed that the surgical technique of debridement was effective in stopping the drainage from the supraspinous bursal region in 5 out of 6 horses that were available for long-term follow-up after surgery.
• A common complication witnessed after the surgery was the formation of purulent wound drainage, whereby pus was seen draining from the wound.
• Two horses needed multiple surgeries to completely get rid of the clinical signs of supraspinous bursitis.
• In terms of microbiological findings, the most frequently isolated organism from the supraspinous bursa was beta-hemolytic Streptococcus species, a type of bacteria.
• After their treatment at the hospital, all horses were discharged. Long-term follow-up was available for 6 horses, and it was noted that all of these could resume their regular activities.

Conclusion

• As per the study, the debridement technique in standing horses is an effective way to treat the clinical signs of supraspinous bursitis. This surgical process improves the condition and enables the horses to get back to their normal routine.
