Corticosteroid injection is a valuable adjunct for treating sports-rel
ated inflammation. Unfortunately these agents are not without toxiciti
es and side effects. It's important, therefore, to choose a corticoste
roid appropriate to the patient, the condition, and the size of the af
fected joint: For example, less soluble agents are generally better fo
r longer-term injuries. Avoiding pitfalls may simply mean heeding the
well-known contraindication of injecting into a tendon. Or it may mean
monitoring blood glucose in a patient who has diabetes, immobilizing
an extremity after injection, or avoiding subcutaneous injection befor
e the target area is reached.
