corticosteroids are effective for rotator cuff disorders
The authors report that the evidence for corticosteroids in shoulder
disorders is weak. This is perhaps because they only examined the Cochrane
reviews which did not report numbers needed to treat. I was part of a
review "Arroll B, Goodyear-smith F. Corticosteroid injections for painful
shoulder a meta-analysis. Br J Gen Pract 2005;55:224-8." where the the
relative risk (RR) for improvement for subacromial corticosteroid
injection for rotator cuff tendonitis was 3.1 (95%CI 1.9-4.9). This
translated to a numbers needed to treat of 3.3 to get an improvement which
is better than almost any thing we do in clinical medicine. The experience
of myself and some of my colleagues that this NNT translates in to
everyday clinical practice. There is an absence of data on harm but plenty
on effectiveness. Thus if we are cautious we can improve the situation for
our patients.
