Rapid Response:

Time for a re-think on the role of corticosteroid injections?

Although Cohen et al[1] did not study the efficacy of corticosteroid
injections against a comparator treatment, their report and the rapid
responses prompted thereafter do focus the spotlight on the role of
corticosteroid injections for like musculoskeletal soft tissue problems
(i.e., lacking in inflammatory markers, chronic (long term) pain states[2-
7]). They rightly concluded that a single study like theirs is not enough
to change practice, yet a broad snapshot of the related evidence base
reveals that there is mounting evidence that raises concern regarding the
mid- to long-term effects of corticosteroid injections and brings into
question their role in the management of musculoskeletal pain states.

A number of studies, which are often cited in support of
corticosteroid injections, have substantiated the frequently made clinical
observation of a rapid and substantial improvement in a range of soft
tissue injuries following these injections (e.g., [7-14]). However, like
the paper of Cohen et al, many of these studies also report poor mid to
long-term outcomes – indicative of delayed recovery, which is also
frequently observed in clinical practice. The report of success rates in
the order of 40-60% at 3 and 6 months, which are often inferior to control
(e.g., adoption of a wait and see policy), across a number of studies[8
,10 ,11 ,14], countries[9 ,12 ,13] and for a range of musculoskeletal pain
sites [7 ,11 ,13] should now be considered as sufficient evidence to
caution against the use of corticosteroid injections for these conditions.
Paralleling this delay in recovery are very high recurrence rates (~72% of
patients reporting success at 6 weeks reported otherwise at 3-12 months),
which out strip recurrence rates (<_10 in="in" control="control" and="and" physical="physical" therapies="therapies" e.g.="e.g." exercise="exercise" manual="manual" therapy="therapy" electrophysical="electrophysical" agents8.="agents8." corroborating="corroborating" the="the" delay="delay" recovery="recovery" higher="higher" recurrence="recurrence" rates="rates" is="is" use="use" of="of" other="other" treatments="treatments" co-interventions="co-interventions" by="by" those="those" receiving="receiving" corticosteroid="corticosteroid" injections="injections" when="when" compared="compared" to="to" physiotherapy="physiotherapy" control8="control8" _11.="_11." individual="individual" papers="papers" like="like" that="that" cohen="cohen" et="et" al="al" may="may" not="not" themselves="themselves" be="be" sufficient="sufficient" evidence="evidence" change="change" practice="practice" but="but" taken="taken" context="context" findings="findings" reported="reported" these="these" cognate="cognate" _15="_15" should="should" raise="raise" concerns="concerns" regarding="regarding" injections.="injections." it="it" now="now" timely="timely" caution="caution" against="against" for="for" chronic="chronic" soft="soft" tissue="tissue" injuries="injuries" are="are" likely="likely" inflammatory="inflammatory" nature.="nature." along="along" with="with" short-term="short-term" gains="gains" patients="patients" informed="informed" real="real" prospect="prospect" long-term="long-term" problems="problems" such="such" as="as" delayed="delayed" rates.="rates." p="p"/> 1.
