Randomized Controlled Trial Comparative Study
Intra-tendon sheath injection for trigger finger: the randomized controlled trial.
The most common technique used for non-surgical treatment of trigger fingers is the direct injection of steroids into the flexor tendon sheath over the metacarpal head. However, this method causes more pian to the patient and can result in tendon rupture due to insertion of needle into the tendon. Carlson and Curtis described the mid-axial injection technique which is simple and relatively painless. ⋯ There were no complications from the injections in both methods. However, the recurrent rate seems to be higher in the conventional technique (p = 0.23). We concluded that the MAI injection technique provided less pain result than the CI technique and there were no complications from this injection technique.
