Abstract

Performing a shoulder joint block under X-ray fluoroscopy has the benefit of confirming the spread of the drug solution by using a contrast agent. The drug solution can reach the target site by changing the position and direction of the needle. The physician can diagnose a rotator cuff injury by identifying leakage of the contrast agent but cannot localize the leakage site.

1 Shoulder and Upper Extremity

The ultrasound-guided method is becoming a widely adopted technique to inject drug solutions into the joints of the shoulders, upper extremities, and other parts. In addition, pre-scanning provides images of the intraarticular anatomy of the shoulder and upper extremity joints and facilitates diagnosis. Direct injection of drug solutions into the injured sites identified through pre-scanning immediately results in analgesia, which leads to an improved range of motion.
