Hydrodissection as a Treatment for Carpal Tunnel Syndrome
- Conditions
- Carpal Tunnel Syndrome
- Interventions
- Procedure: Regular InjectionProcedure: Hydrodissection
- Registration Number
- NCT03427983
- Lead Sponsor
- Mayo Clinic
- Brief Summary
This is a pilot study designed to acquire data on the added value of hydrodissection when using a corticosteroid injection as a treatment for patients with carpal tunnel syndrome. Hydrodissection is part of a standard clinical care injection under ultrasound guidance in which the fluid is used to separate the nerve from surrounding structures.

- Target Recruitment
- 20
- Clinical CTS diagnosis with indication for steroid injection as determined by attending physician (if both hands are involved, only the side with the most severe CTS as indicated by electromyography (EMG) will be included) AND
- adult men and women between age 21 and 80 AND
- no more than moderate severity as indicated by EMG AND
- symptoms of numbness or tingling for at least 4 weeks in the median nerve distribution area AND
- classic or probable carpal tunnel syndrome on Katz-Stirrat hand diagram AND
- ability to complete English-language questionnaires and clinical evaluations AND
- is reachable by phone for the follow up contact
Exclusion criteria are largely based on the premises of only including patients with idiopathic carpal tunnel syndrome without expected interferences of the acquisition of the ultrasound images or corticosteroid treatment.
- Previous Carpal Tunnel Release (CTR) or other volar wrist surgery on the study hand OR known tumor/mass OR deformity of the study hand/wrist OR
- previous history of steroid injection into carpal tunnel OR
- currently taking a steroid medication either regularly or on an as needed basis OR
- any of the following clinical diagnoses or conditions: Cervical radiculopathy; rheumatoid or other inflammatory arthritis, including gout; osteoarthritis in the wrist; renal failure; sarcoidosis; peripheral nerve disease; diabetes, thyroid disease or other metabolic disorder; pregnancy; amyloidosis; or major trauma (fractures or complete ligamentous tears) to the ipsilateral arm OR
- prisoners, institutionalized individuals, or others who may be considered vulnerable populations, such as individuals with dementia

Group Intervention Description US-guided regular injection Regular Injection US in-plane injection with corticosteroid and 1cc of lidocaine. Total of 2cc. US-guided hydrodissection Hydrodissection US in-plane injection with corticosteroid and 1cc of lidocaine, and 3cc of saline. Total of 5cc.
- Primary Outcome Measures
Name Time Method Tolerance 6 months Acquire data on the added value of hydrodissection when using injection as a treatment for patients with Carpal Tunnel Syndrome (CTS). Questionnaires will be used to assess level of tolerance using a 10 point Likert Scale.
- Secondary Outcome Measures
Name Time Method Overall Pain 6 months The visual analog scale will be used to assess overall pain. This is a 1-10 Likert scale.
Additional Treatment 6 months After 6 months patients will be asked whether they have had additional treatment for their Carpal Tunnel Syndrome after the ultrasound guided injection. The date, location, and time frame of the additional treatment will be recorded.
Clinical Severity of Carpal Tunnel Syndrome 6 months The Boston Carpal Tunnel Assessment questionnaire will be used to assess both symptom severity and functional status using a 19 item questionnaire with scores between values 1-5.
