Subacromial impingement syndrome is one of the most common shoulder diseases, and it can lead to significant limitations in activities and lifestyle modificationsHowever, there is a lot of variability in the corticosteroid injection technique, and one explanation of variability could be the method by which corticosteroid injections are administered, such as being given aim various doses (low or high), volume (low or high), and the injection techniqueThe patient still found the main complication of lidocaine combined with corticosteroids to be more neurotoxicity after subacromial injection with the standard SCI mixed solution with anesthetic solution (lidocaine) and corticosteroid solution. The main complication of the patient was where lidocaine was combined with corticosteroids resulting in more neurotoxicity after subacromial injection. Slurred speech, tinnitus, circumoral paresthesia, feeling faint (vasovagal syncope), seizures or loss of consciousness, cardiac arrhythmias, respiratory arrest, and cardiac arrest, all seem to be signs and symptoms of lidocaine toxicityGenerally, when compared to low-volume CI, HVCI of lidocaine is associated with a higher risk of consequences, in particular, soft tissue irritation. And furthermore, when corticosteroids are at lower concentrations, the steroid effects decrease, which should only be acceptable if being using for therapeutic purposedWe hypothesized that VLVCI was not of significance to the functional score and VAS compared to in the HVCI. This study difference from the others studies due to aims to use VLVCI to increase the most potentially beneficial steroid concentration effect while avoiding the complications associated with lidocaine and compare the efficacy of corticosteroid injections in the SIS using HVCI and VLVCI (pure corticosteroid injection without analgesic solution combination).
