Comparing Corticosteroid Preparation and Dose in the Improvement of Shoulder Function and Pain: A Randomized, Single-Blind Pilot Study.

Introduction: Shoulder pain may arise from inflammation of the bursa separating the supraspinatus tendon from the coracoacromial ligament and acromion. The optimal treatment dose and preparation of intrabursal corticosteroid injection are unknown.

Methods: This single-blinded equivalence study recruited 62 subjects randomizing them to one of following four arms: methylprednisolone 20 mg, methylprednisolone 40 mg, triamcinolone acetonide 20 mg, or triamcinolone acetonide 40 mg.

Rilonacept in the treatment of subacromial bursitis: A randomized, non-inferiority, unblinded study versus triamcinolone acetonide.

Introduction: Subacromial bursitis is caused by inflammation of the bursa that separates the superior surface of the supraspinatus tendon from the overlying coraco-acromial ligament and acromion. While multiple cytokines are implicated, interleukin-1 beta appears to play a prominent role. Rilonacept, an interleukin-1 trap, may be an alternative to corticosteroid injection for the management of this condition.
