Long-Term Clinical Outcomes and Patient Satisfaction Following Ultrasound-Guided Hydrodissection for Carpal Tunnel Syndrome: A Comprehensive Reviews

Long-Term Outcomes and Satisfaction After Ultrasound-Guided Hydrodissection for CTS

Abstract

Carpal Tunnel Syndrome (CTS) is a prevalent condition caused by compression of the median nerve, leading to symptoms such as pain, numbness, and weakness in the hand. Traditional treatments, including splinting, corticosteroid injections, and surgery, offer varying degrees of symptom relief but are often associated with limitations such as short-term efficacy or long recovery times. Ultrasound-Guided Hydrodissection (USGH) has emerged as a minimally invasive alternative for treating CTS, utilizing real-time ultrasound imaging to guide fluid injection around the median nerve, reducing nerve compression and enhancing nerve gliding. This procedure has gained attention due to its precision, reduced complication rates, and faster recovery compared to surgical interventions. This review explores the long-term clinical outcomes and patient satisfaction associated with USGH for CTS. The analysis reveals that USGH provides sustained symptom relief, with patients experiencing reductions in pain, improved functional outcomes, and enhanced nerve conduction for up to a year or more. Patients report high satisfaction levels, largely attributed to the minimally invasive nature of USGH, shorter recovery times, and minimal postoperative discomfort. While most patients benefit from long-term symptom relief, some experience recurrence of symptoms after several months, though re-treatment remains a viable option. Complications associated with USGH are rare and typically minor, including temporary pain, swelling, or bruising at the injection site. Serious complications, such as nerve damage or infection, are infrequent due to the precision afforded by ultrasound guidance. Future research should focus on randomized controlled trials and the integration of regenerative medicine to improve long-term outcomes.
