Management The first step in treating the joint sepsis is to begin systemic antibiotics. In foals, Amikacin and Potassium penicillin are appropriate. Long term treatment is required to ensure that the MIC levels are achieved in the synovial fluids. The next step is to perform a joint lavage. We will use a pH-adjusted fluid. This will aid in flushing out the bacteria, inflammation products, and purulent material in order to improve the efficiency of the antibiotics. Antiinflammatory drugs can be used short-term with caution that gastric ulcers are not formed. Foals are more susceptible to ulceration with NSAID use. Because this is a low-grade infection, we will refrain from using any antiinflammatories unless the condition worsens and they would be more appropriate. Rest and immobilization of the limb is required for healing to occur. We will repeat the radiographs in one week to check for advancement of the disease into the bone. Prognosis The prognosis for a foal with a single infected joint is guarded. There is a better prognosis in foals than in adults. The absence of bony lesions improves the prognosis.
