title: A modified technique for needle localization in arthrography of the shoulder.
abstract: The authors describe a simple technique for establishing satisfactory position of the needle in the shoulder joint for arthrography. Local anesthetic is placed in the hub of the spinal needle and is often drawn into the joint when the needle enters, causing a sudden drop in the fluid level.
