Chronic osteoarthritis in a captive mountain lion (Felis concolor)

Chronic osteoarthritis in a captive mountain lion (Felis concolor)

A 23-year-old male Mountain Lion (Felis concolor) died after developing chronic lameness in the Zoological Park “El Pinar”, Caracas-Venezuela. Were practice euthanasia. Grossly, the radio-ulnar- humeral joint had severe bilateral lesions on the surface of the articular cartilage, with erosion of the cartilage and exposure of subcondral bone. There was approximately 1 ml of synovial fluid that was yellowish, and had a decreased viscosity. Histopathology revealed severe erosion and ulceration of the articular cartilage, with variable degrees of exposure of the subcondral bone. Bone tissue had defective osteoid matrix formation, and mineralization failure, resulting in loss of bone lamellae. Radiographic changes included decreased cortical density, trabecular growth pattern, fractures and microfractures. Failure in the formation of bone callus, and presence of osteophytes. These reports support the osteoarthritis and degenerative disease joint under conditions of captivity in a mountain lion.

Un león de montaña (Felis concolor), macho de 23 años de edad Montaña desarrollo una claudicación crónica en el parque zoológico “El Pinar”, Caracas-Venezuela. Se le practico eutanasia. Macroscópicamente, la articulación humero-radio-cubital, presento severas lesiones bilaterales en la superficie del cartílago articular, con erosión del cartílago y exposición del hueso subcondral. Aproximadamente 1 ml de líquido sinovial presento de color era amarillento y una viscosidad disminuida. La histopatología reveló una severa erosión y ulceración del cartílago articular, con grados variables de exposición del hueso subcondral. El tejido óseo presento defectuosa formación de la matriz osteoide, con fallas en la mineralización, lo que resulta en la pérdida de laminillas óseas. Los cambios radiográficos incluyen disminución densidad cortical, el patrón de crecimiento trabecular, las fracturas y microfracturas. Fallas en la formación de callo óseo, y la presencia de osteofitos. Estos resultados son consistentes con artrosis y enfermedad degenerativa que son comunes en condiciones de cautiverio en el león de montaña.
