Podotrochlear bursa endoscopy in the horse: a cadaver study.

Area of Science:

• Veterinary Medicine
• Diagnostic Imaging
• Equine Surgery

Background:

• Podotrochleosis, commonly known as navicular disease, is a significant cause of lameness in horses.
• Accurate diagnosis is crucial for effective treatment and management of equine foot conditions.
• Endoscopy offers a minimally invasive approach to visualize internal structures, but its utility in the podotrochlear bursa requires evaluation.

Purpose of the Study:

• To assess the diagnostic capability of podotrochlear bursa endoscopy in horses.
• To correlate endoscopic findings with radiographic and pathological results.
• To determine the feasibility and potential clinical relevance of this technique for diagnosing podotrochleosis.

Main Methods:

• A descriptive study was conducted on seventeen equine cadaver forelimbs.
• Standard radiographic views of the navicular region and bursography were performed.
• Endoscopic examination of the podotrochlear bursa was conducted using a 4-mm arthroscope, followed by dissection for verification.

Main Results:

• Radiographic scores for the navicular bone varied, with abnormalities noted in limbs scoring 1 and 3.
• Endoscopic examination identified abnormalities such as tendon fibrillation and fibrocartilage defects in three limbs.
• Correlation between endoscopic findings and gross pathology was variable, with challenges in evaluating bursae ipsilateral to the arthroscope portal.

Conclusions:

• Podotrochlear bursa endoscopy is a feasible technique for equine diagnostics.
• The procedure shows potential for identifying early abnormalities associated with podotrochleosis.
• Endoscopic examination may enhance the identification of pathological changes within the navicular bursa in horses.
