Effectiveness of ultrasound-guided local steroid injection to the wrist for the treatment of carpal tunnel syndrome: Is it worth it?

Abstract

BackgroundCarpal tunnel syndrome (CTS) is caused by compression of the median nerve at the wrist level and the most frequent entrapment neuropathy in the upper limb. It can be treated with surgical or non-surgical methods. When nonsurgical treatment is indicated, a local corticosteroid injection into the carpal tunnel can be used to reduce pain and tingling sensation. To assess the clinical outcomes and effectiveness of patient satisfaction following ultrasound-guided steroid injection for the treatment of carpal tunnel syndrome.ResultsThe study comprises 44 female (73%) and 16 (27%) male patients, with a mean age of 57 (27–84) years. Thirty-one patients were left-handed and 29 right-handed. Twenty-six (43%) injections were performed on the right side, 8 (13%) on the left, and 26 were bilateral. Fifty-six hands of thirty-seven (70%) patients reported significant improvement symptoms, five (8%) had temporary improvement with recurrence, seventeen patients (28%) failed to improve, and one patient’s symptoms have resolved before intervention. Among temporary responders and nonresponders, two were referred to the neurologist for further evaluation. Out of twenty patients, fourteen patients (23%) had surgical decompression of carpal tunnel with complete resolution of symptoms, four patients had opted for repeat injections, and two patients refused any further intervention.ConclusionsThe use of ultrasound-guided injection for the treatment of mild to moderate carpal tunnel syndrome is a practical procedure before offering surgical treatment. It is also appropriate for the patient with significant medical problems or not willing to undergo surgical intervention. Its ultrasound guide reduces injection-related complications, improves patient satisfaction, is cost-effective, and improves patient compliance.
