PROTEINOGRAMA DE LÍQUIDO SINOVIAL E ANÁLISE HISTOPATOLÓGICA DAS ARTICULAÇÕES METACARPO- FALANGEANAS DE MUAR COM OSTEOARTRITE DESENCADEADA POR DEFORMIDADE FLEXURAL (Proteinogram of liquid synovial and histopathological analysis of metacarpophalangeal joints of the hinny with osteoarthritis triggered by flexor deformity)

摘要: The flexural deformities are characterized by permanent hyperflexion of one or more joint areas, consequently, the bad shaping overload structures that form joints triggering arthritis osteoarthritis. This aims to report a case bilateral tendon contracture metacarpophalangeal in mule who did not respond conservative treatment. radiographic exam visualized signs consistent with osteoarthritis, being intense left. After tenotomy deep digital flexor it was found correction, but there no regression local inflammatory process, deciding euthanasia. In histopathological examination tissues were observed loss cartilage architecture and large areas fibrosis both joints, while also left cell hypertrophy hyperplasia synovial membrane slight infiltration neutrophils. Samples fluid showed adequate viscosity, reddish coloration turbidity; protein concentrations liquid high α1-acid glycoprotein, ceruloplasmin IgA IgG on sides, total proteins, albumin haptoglobin increased only hip. We can conclude 15 day intervals for animal care associated constant repetitive friction during locomotion, due deformity, caused an process place led osteoarthritis right joint.
