Clinical Trial Summary

Multicenter prospective single-arm trial of subjects with symptomatic Carpal Tunnel Syndrome treated with Ultrasound Guided Carpal Tunnel Release (CTR-US) in an office-based setting.


Description:

Multicenter prospective single-arm trial of subjects with symptomatic Carpal Tunnel Syndrome treated with Ultrasound Guided Carpal Tunnel Release (CTR-US) in an office-based setting reporting the safety and effectiveness of office-based carpal tunnel release with ultrasound guidance (CTR-US) in patients with symptomatic carpal tunnel syndrome (CTS).

Subject has a valid smart phone number and/or email address to receive and answer follow-up questionnaires Exclusion Criteria: 1. Prior surgery on the target wrist or hand with the exception of (a) trigger finger release or similar minor finger procedure (e.g., digital ganglion cyst removal, foreign body removal) that has clinically recovered, or release for DeQuervain's syndrome (1st dorsal compartment) that has clinically recovered* 2. History of prior surgical CTR in the target hand* 3. History of infection in the target hand* 4.

Planned surgical or interventional procedure on the contralateral hand within 3 months of the target hand procedure date* 6. Corticosteroid injection in the target hand within 6 weeks of study procedure date* 7. Presence of additional process in the target hand requiring additional intervention beyond carpal tunnel release (e.g. neurolysis, mass removal, tenosynovectomy)* 8. Clinically significant degenerative arthritis of the upper limb (shoulder to hand) on the target side* 9. Clinically significant inflammatory disease (including tenosynovitis) of the upper limb (shoulder to hand) on the target side* 10. Clinically significant trauma or deformity of the upper limb (shoulder to hand) on the target side* 11. Clinically significant vascular disease (including Raynaud's phenomenon) of the upper limb (shoulder to hand) on the target side* 12. Clinically significant neurological disorder (including complex regional pain syndrome) of the upper limb (shoulder to hand) on the target side* 13. Systemic inflammatory disease (e.g., rheumatoid arthritis, lupus) 14. Amyloidosis 15. Chronic renal insufficiency requiring dialysis 16. Diabetes not controlled by a stable dose of medication 17. Uncontrolled thyroid disease 18. Pregnant or planning pregnancy in the next 24 months 19. Workers' compensation subjects 20. Inability to provide a legally acceptable Informed Consent Form and/or comply with all follow-up requirements 21. Subject has other medical, social, or psychological conditions that, in the opinion of the investigator, preclude them from receiving the pre-treatment, required treatment, and post-treatment procedures and evaluations Note: An asterisk (*) denotes that this criterion must be applied to the target hand for unilateral CTR-US procedures, or to both hands for simultaneous bilateral CTR-US procedures. Clinically significant is defined as likely to interfere with the performance of the procedure in a safe and/or effective manner.

Intervention

Device:
Ultrasound Guided Carpal Tunnel Release (CTR-US)
The UltraGuideCTR is a commercially available medical device specifically developed to facilitate CTR-US. The device is a single-use, hand-held device that is inserted into the carpal tunnel through a small (typically < 5 mm) wrist incision using continuous US guidance. The working tip of the UltraGuideCTR consists of two inflatable balloons that border a centrally located, retractable retrograde cutting knife. When inflated with sterile saline, the balloons increase the diameter of the tip from 4 mm to 8 mm. After the tip is positioned within the transverse safe zone of the carpal tunnel, the balloons are inflated to create space in the carpal tunnel, the blade is activated, and the TCL is transected in a retrograde manner. Following TCL transection, the blade is recessed, the balloons deflated, and the device is removed. The TCL is probed to ensure a complete release. The entire procedure is performed using US guidance.

Outcome

Type Measure Description Time frame Safety issue
Primary Boston Carpal Tunnel Questionnaire - Symptom Severity Scale (BCTQ-SSS) Scoring for the BCTQ- SSS ranges from 1 to 5, with higher scores indicating more severe symptoms, and is calculated as the mean of each response. The change in BCTQ-SSS score at the 3-month follow-up relative to baseline. 3 Months
Secondary Time to Return To Normal Daily Activities (RTA) Time to return to normal daily activities will be defined as the number of days between treatment and the time the subject reports returning to normal daily activities, irrespective of work status. 3 Months
Secondary Time to Return To Work Among Employed Subjects (RTW) Time to return to work will be defined as the number of days between treatment and the time the subject reports returning to work in any capacity. 3 Months
Secondary Boston Carpal Tunnel Questionnaire - Functional Status Scale (BCTQ-FSS) Scoring for the BCTQ-FSS ranges from 1 to 5, with higher scores indicating more functional limitation, and is calculated as the mean of each response. The change in BCTQ-FSS score at the 3-month follow-up relative to baseline. 3 Months
Secondary Michigan Hand Questionnaire (MHQ) Michigan Hand Questionnaire (MHQ) is a validated, hand-specific questionnaire consisting of 37 questions in 6 domains:
Overall hand function
Activities of daily living
Work performance
Pain
Aesthetics
Satisfaction
Change in the total MHQ score as well as each of its 6 domains score at the 3-month follow-up relative to baseline.
3 Months
Secondary Numeric Pain Scale Subjects will be asked to rate their wrist pain severity on a scale of 0 to 10, where 0 represents "no pain" and 10 represents "worst possible pain". The change in Numeric Pain Scale score at the 3-month follow-up relative to baseline. 3 Months
Secondary EuroQoL 5-Dimension 5-Level (EQ-5D-5L) The EQ-5D-5L measures quality of life across 5 domains: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension is scored on a 5-level severity ranking consisting of: no problems, slight problems, moderate problems, severe problems, unable to/extreme problems. The change in EQ-5D-5L score at the 3-month follow-up relative to baseline. 3 Months
Secondary Device and/or Procedure Related Adverse Events Incidence of device- or procedure-related AEs within 90 days of treatment. 3 Months
Secondary Global Satisfaction Subjects will be asked to rate their satisfaction with the carpal tunnel release procedure and how likely they are to recommend their carpal tunnel release procedure to a friend or colleague. 3 Months
