Complications after ultrasound-guided carpal tunnel release: a case series.

In a retrospective analysis, data from patients who underwent open revision after ultrasound-guided release between February 2021 and December 2023 were reviewed. These patients experienced persistent, worsened or new symptoms. Clinical symptoms, complications and surgical techniques were assessed. Of 14 patients undergoing revision, nine had an incomplete release of the flexor retinaculum. Five patients had major complications like nerve or vessel lesions. Our findings indicate that although ultrasound-guided release is effective, it should only be done by physicians experienced in nerve sonography and hand surgery.Level of evidence: IV.
