Importance of immobilization after intraarticular glucocorticoid treatment for elbow synovitis: a randomized controlled study.

OBJECTIVE

To investigate whether better treatment results might be achieved with postinjection rest following intraarticular glucocorticoid treatment for elbow synovitis.

METHODS

Ninety patients with rheumatoid arthritis and elbow synovitis were treated with 20 mg of intraarticular triamcinolone hexacetonide and randomized to either a 48-hour immobilization in a triangular sling (n = 46) or to normal activity without restrictions (n = 44). The primary end point was relapse of synovitis. In addition, pain, function according to a self-assessment questionnaire (the Patient Rated Elbow Evaluation), and range of movement were followed for 6 months.

RESULTS

Thirteen relapses occurred in the rest group and 8 in the active group (results not significant). The secondary measures showed no statistically significant differences between the groups.

CONCLUSION

Immobilization procedures do not improve the outcome of intraarticular glucocorticoid therapy for elbow synovitis. In future guidelines for such treatment of the upper extremity, normal activity after the injection should be recommended.
