We aimed to determine prognostic factors for a successful long\u2010term outcome. <jats:italic>Methods<\/jats:italic>: We prospectively followed 113 patients who received an injection for CTS. Clinical, electrophysiological, and ultrasonographic tests were done at baseline, and clinical outcome was evaluated after 1, 3, 6, and 12 months. The primary outcome measure for success was no need for additional treatment (e.g., surgery) within 1 year. <jats:italic>Results<\/jats:italic>: After 1 month, most patients improved, but after 12 months 67.4% had surgery. Patients with a successful outcome had a lower median nerve ultrasonographic cross\u2010sectional area (CSA) at the pisiform bone, a lower swelling ratio, and a lower symptom severity score. <jats:italic>Conclusions<\/jats:italic>: Less pronounced median nerve swelling measured by ultrasonography may indicate a less severe stage of CTS, which is more likely to respond to treatment with a corticosteroid injection.
