For the majority of joints in most small to large dogs, 40 mm/1.5” length is ideal 25 mm is sufficient for the carpus and hock joints, while for the shoulder and hip joint in giant breeds >40 mm/1.5” may be necessary.
#SYNOVIAL FLUID ANALYSIS CHART SKIN#
Length depends on the distance of the joint cavity from the skin surface and the size of the animal. The single most useful test in distinguishing between OA and inflammatory joint disease is synovial fluid analysis.Īrthrocentesis for synovial fluid analysis is a relatively simple procedure to perform, though it remains a surprisingly under-utilised tool in veterinary medicine. Since the treatment of OA is very different from that used for inflammatory joint disease, an accurate diagnosis is important. Infectious and immune-mediated inflammatory arthropathies.Inflammatory and non-inflammatory arthropathies.Synovial fluid analysis can be used to differentiate between: Inflammatory joint disease, infection and immune-mediated diseases are an infrequent but significant cause of joint pain and lameness. Osteoarthritis (OA) is by far the most common type of joint disease in dogs. Disease processes of the synovial membrane or articular cartilage can alter the characteristics of synovial fluid.
Polysulfated glycosaminoglycans (PGAGs) contribute to the viscosity of the synovial fluid. Synovial fluid is a dialysate of plasma that contains glycoproteins from the synovial membrane type B cells.
