Combined Corticosteroid With Low Volume Compared to High Volume in Impingement Syndrome

Study Overview
=================
Brief Summary
-----------------
This study aims to assess and compare the effectiveness of two different volumes of local anesthetic combined with 40mg of triamcinolone for subacromial injections in treating patients with rotator cuff impingement syndrome

Detailed Description
-----------------
Patients with rotator cuff impingement syndrome were randomized to undergo subacromial injection with 10mL total volume of 1% lidocaine plus 40mg triamcinolone acetonide (n = 22), or a 4mL total volume of 1% lidocaine plus 40-mg triamcinolone acetonide (n = 23). Evaluations using a visual analog scale (VAS) for pain during motion, and the Western Ontario Rotator Cuff Index (WORC) were completed before treatment and 30 minutes, 2 weeks, and 8 weeks after injection.
