Answer

Corticosteroid injection in the area of tendon sheath thickening is considered to be the first-line treatment of choice for TF. [49, 50, 51, 52, 10] Research in 2009 concluded that the most successful and cost-effective management strategy for TF is the algorithm of two steroid injections prior to surgical intervention, if needed. [53]

A variety of preparations have been used—most commonly prednisolone, dexamethasone, and triamcinolone—in the steroid injection treatment of TF, and most are uniformly successful in relieving symptoms. [54, 49, 55, 56]

A highly satisfactory rate of success can be predicted in female patients and in patients with single digit involvement, short duration of symptoms (ie, < 4 months), no associated conditions (eg, RA, diabetes mellitus [DM]), or a discrete, palpable nodule. (Patients with RA or DM seem to be more resistant to injection treatment.) [26, 27, 57]
