Area of Science:

  • Veterinary Medicine
  • Biomineralization
  • Equine Orthopedics

Background:

  • Articular cartilage in horses is susceptible to pathological changes.
  • Crystal deposition diseases are known in human and animal joints.
  • Understanding equine joint pathology is crucial for animal welfare.

Purpose of the Study:

  • To identify and characterize crystal deposits in equine articular cartilage.
  • To investigate the prevalence of calcification in equine fetlock joints.
  • To explore the potential role of these crystals in equine arthritis.

Main Methods:

  • Scanning electron microscopy (SEM) for morphological analysis.
  • X-ray diffraction (XRD) for crystal structure identification.
  • Gross examination of 89 equine fetlock joints.

Main Results:

  • Crystal deposits identified as octacalcium phosphate and calcium pyrophosphate dihydrate.
  • Visible calcification found in 10 out of 89 examined equine fetlock joints.
  • SEM and XRD confirmed the presence and composition of the crystals.

Conclusions:

  • Crystal deposition is present in equine articular cartilage.
  • These findings suggest crystals may mediate or directly cause arthritis in horses.
  • Further research is warranted to elucidate the pathogenic mechanisms.
