Does injection of steroid into the bursa prevent recurrence of olecranon bursitis?

Three Part Question

In [adults with olecranon bursitis which has been drained by needle aspiration] is [injection with a steroid better than conservative management alone] at [preventing recurrence]?

Clinical Scenario

A 56 year-old male patient attends review clinic with recurrent olecranon bursitis. The bursitis was aspirated one week previously, and the resulting culture is negative. You wonder whether re-aspiration and bursal steroid injection will prevent recurrence.

Unwanted effectsWithin the steroid group, 3 patients developed septic olcranon bursitis and 5 developed skin atrophy (none in conservatively treated group)

Comment(s)

Both studies show decrease in size of bursal swelling following steroid injection. However, the retrospective cohort study suggests a significant risk of septic olecranon bursitis and skin atrophy following this intervention. This increased risk is not shown in the only randomised controlled trial performed in this area. This is a well conducted trial, but with small numbers and no power calculation.

Clinical Bottom Line

Insufficient evidence exists at present to prove that the benifits of steroid injection outway the risk of unwanted effects. A larger ransomised controlled trial would be welcome.
