Rotator cuff impingement: correlation between findings on MRI and outcome after fluoroscopically guided subacromial bursography and steroid injection.

OBJECTIVE. The purpose of this study was to describe the use of fluoroscopically guided subacromial bursography in the management of rotator cuff impingement and to correlate clinical outcome with preprocedural MRI findings.MATERIALS AND METHODS. Sixty-nine patients with clinically and MRI proven subacromial impingement referred for fluoroscopic subacromial bursography and steroid injection between January 2004 and January 2006 were included in the study. After contrast-enhanced bursography, each patient received an injection of 80 mg of methylprednisolone and 1–2 mL of 0.25% bupivacaine into the bursa. Outcome was determined retrospectively and classified as complete resolution of symptoms, partial resolution of symptoms, or no change. MRI findings of impingement were graded according to severity. Outcome was evaluated as complete resolution and as complete or partial resolution in relation to MRI findings, duration of symptoms, age, and sex.RESULTS. Complete resolution of symptoms was recorded in 40 (58...
