Sonographic Changes After Ultrasound-Guided Release of the Transverse Carpal Ligament: A Case Report

PM R. 2018 Oct;10(10):1125-1129. doi: 10.1016/j.pmrj.2018.02.018. Epub 2018 Mar 6.


Carpal tunnel syndrome is the most common entrapment neuropathy, resulting in 500,000 carpal tunnel release (CTR) surgeries and a total cost of more than 2 billion dollars annually in the United States. Although initially performed via a large (3-5 cm) palmar incision, CTR techniques have continually evolved to reduce incision size, recovery times, postoperative pain, and improve cosmesis and clinical outcomes. More recently, multiple authors have reported excellent results after ultrasound-guided carpal tunnel release (USCTR) using a variety of techniques, and one prospective randomized trial reported faster recovery after USCTR compared with traditional mini-open CTR. However, there is a paucity of data with respect to changes in the median nerve after USCTR. This case report presents the functional outcomes and pre- and postprocedure ultrasound images of a patient after USCTR with 3-month follow-up. LEVEL OF EVIDENCE: V.
