[Subcutaneous atrophy following steroid injection in the treatment of trigger finger].

Trigger finger (TF), also known as stenosing tenosynovitis, is a rather common condition that causes entrapment of the flexor tendon at the site of the annular pulley. The accepted first-line treatment for TF is injection of long-acting corticosteroid in the involved flexor tendon sheath. This treatment is characterized by a high success rate and a low level of reported adverse effects in the literature. We report a case of subcutaneous atrophy after steroid injection in the treatment of TF.
