Injection of NSAID better than corticosteroid in patients with shoulder impingement syndrome

While previous research has indicated that nonsteroidal anti-inflammatory drug (NSAID) injection is useful in the treatment of impingement syndrome at the shoulder, but until recently corticosteroid injection is common treatment for this disorder, despite it is associated with adverse effects of tendon rupture, depression of the skin because loss of tissue, and changes to articular cartilage.

Due to the risk of corticosteroid injection and positive results of previous NSAIDs’ research, the researchers initiated the study to compare the effectiveness between those treatments.

Presented at 2011 annual meeting of the American Orthopaedic Society for Sport Medicine (AOSSM), held on July 10, 2011, the lead of study authors who presented the findings, Kyong Su Min, MD, from the Madigaan Healthcare System in Tacoma, said that both of those treatments have a good response. However, he says, “only the NSAID group had a sustained response.”

Another clinical advantage, he said, the NSAID injection group had no report of damage to cartilage or tissue atrophy, and the injection is not limited by frequency of use.

The study involved 48 patients who were randomly received either a single injection of 6 cc of 1% lidocaine with epinephrine and 40 mg triamcinolone, or 6 cc of 1% lidocaine with epinephrine and 60 mg ketorolac.
All of participants diagnosed with isolated external shoulder impingement syndrome.

However, other experts cautioned that although NSAID injection of ketorolac may not have adverse effect such as above mentions than with corticosteroid injections, but NSAIDs are not completely without side effects as it can cause bleeding, dangerous effect when taking oral NSAIDs along with injections, having gastric ulcer, and dose-dependent effects.
Even so, because the study seem valid, they see interesting solution for the treatment, especially when corticosteroid injection failed.
