Injection Treatment for Flexor Tenosynovitis of the Finger

A 47-year-old man with rheumatoid arthritis had considerably restricted flexion of the middle finger, and occasionally the finger could not be extended after flexing (trigger finger). The skin is cleansed. A thin needle is slowly inserted perpendicular to the tendon, and the patient is asked to flex the finger until the tip of the needle touches the surface of the tendon, making the syringe tilt forward during finger flexion (in the video this occurs at the second flexion). At this point, the needle is retracted about 1 mm, and the finger is flexed again to ascertain that the tip of the needle is not in the tendon any more. 1 ml of methyl prednisolone and bupivacaine combination is injected into the tendon sheath. The puncture site is covered with self-adhesive sterile dressing and is kept dry until the next day. In severe tenosynovitis, and especially in the case of a trigger finger, it is advisable to administer another injection into the same tendon sheath from the volar side about 1 cm proximal from the skin groove at the base of the finger Corticosteroid Injection for Trigger Finger in Adults.
