A 42-year-old woman had a two-month history of trigger finger. A snap is audible and a jerking movement of the finger is observed when the patient flexes and extends her finger. The movement of the swollen part of the tendon that is trapped in a narrow part of the tendon sheath in the palm is felt by palpation. A thin needle is inserted perpendicular towards the tendon and the patient is asked to flex her finger until the tip of the needle touches the surface of the tendon, making the syringe tilt forward during finger 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 methylprednisolone and bupivacaine is injected into the tendon sheath «Corticosteroid and lidocaine injections in combination may be more effective than lidocaine alone for the treatment of trigger finger.»C.
