Clinical Outcomes of USCTR vs. mOCTR
Clinical Outcomes of Carpal Tunnel Release With and Without Ultrasound Guidance
Carpal tunnel syndrome (CTS) is the most common peripheral entrapment neuropathy and affects 3-6% of adults in the United States. In patients with severe or refractory symptoms, carpal tunnel release (CTR) represents the definitive management option, and over 550,000 CTRs are performed annually in the United States with over 90% of patients reporting clinical improvement. Currently available CTR techniques include mini-open CTR via a single, 1-3 cm palmar incision (mOCTR), endoscopic CTR via one (wrist) or two (wrist and palm) 1-2 cm incisions (ECTR), and ultrasound guided CTR via a single < 1 cm wrist or palmar incision (USCTR). The primary objective is to assess the impact of USCTR vs mOCTR in a military population. This study is a multi-site prospective randomized comparative trial.
Participants with CTS will be randomized to a study arm and receive treatment with ultrasound guided carpal tunnel release (USCTR) vs. traditional mini-open carpal tunnel release (mOCTR). All patients will be followed for a period of 24 months with respect to standard clinical data, military relevant data, and validated patient related outcome measures (PROMs). Data will be collected at 1 week, 2 weeks, 3 weeks, 1 month, 6 weeks, 3 months, 6 months, and 12 months, and 24 months post-CTR procedure.
Investigators hypothesize that USCTR using the SX-One MicroKnife® will safely and more-effectively improve symptoms of carpal tunnel syndrome compared to traditional mOCTR, with less loss of military duty days.

Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Measure the effect of USCTR vs mOCTR on the longitudinal change in QuickDASH.
Time Frame: Change from baseline to 1 week, 2 weeks, 3 weeks, 1 month, 6 weeks, 3 months, 6 months, 12 months, and 24 months post CTR procedure
|
QuickDash is a region-specific PROM consisting of 11 items measuring the difficulty in performing physical activities relevant to shoulder, arm or hand function.
Each item is scored on a scale of 1-5 and a final score of 0 to 100 is calculated, with higher scores representing greater degrees of upper extremity disability (0 points indicate no disability and 100 points indicates maximum disability).
|
Change from baseline to 1 week, 2 weeks, 3 weeks, 1 month, 6 weeks, 3 months, 6 months, 12 months, and 24 months post CTR procedure
|
Measure the effect of USCTR vs mOCTR on the longitudinal change in BCTQ-S.
Time Frame: Change from baseline to 1 week, 2 weeks, 3 weeks, 1 month, 6 weeks, 3 months, 6 months, 12 months, and 24 months post CTR procedure
|
The BCTQ is a PROM for CTS and is the most commonly used outcome measure for CTS.
Each item on the 11-item symptom severity scale (BCTQ-S) is graded from 1 (mildest) to 5 (most severe).
Outcomes are typically recorded as a mean score.

Time Frame: Captured at 1 week, 2 weeks, 3 weeks, 1 month, 6 weeks, 3 months, 6 months, 12 months, and 24 months post CTR procedure
|
Participants will rate satisfaction with the following: completely dissatisfied, mostly dissatisfied, somewhat satisfied, neither satisfied or dissatisfied, somewhat satisfied, mostly satisfied, or completely satisfied. Completely dissatisfied with represent the lowest score, and completely satisfied will represent the highest score. |

|
The 11-item NRS scale is a unidimensional measure of pain intensity.
It is a segmented numeric version of the visual analog scale in which participants will select a whole number (0-10 integers) that best reflects the intensity of their pain.
The scale ranges from '0' representing one pain extreme (e.g.
no pain) to '10' representing the other pain extreme (e.g.
worst possible pain).

Participant self-reported pain medication usage.
Participant will respond with responses ranging from "less than once a week', "once a week", "several times a week", "daily", "multiple times per day", "or did not use".
"Did not use" will represent the minimum value, and "multiple times per day" will represent the maximum value.

Using the 11-item Pain Numeric Rating Scale (NRS), compare the distributions of participant self-reported pain at both pre- and immediately -post CTR procedure between the USCTR and mOCTR groups. The 11-item NRS scale is a unidimensional measure of pain intensity. It is a segmented numeric version of the visual analog scale in which participants will select a whole number (0-10 integers) that best reflects the intensity of their pain. The scale ranges from '0' representing one pain extreme (e.g. no pain) to '10' representing the other pain extreme (e.g. worst possible pain). |

The 4-item Carpal Tunnel Syndrome Palmer and Incision Pain questionnaire inquiries about severity of pain.
Each item has five-six possible response options which range from 1 (no pain) to 5/6 (very severe).
The symptom score is the mean of all answered items; higher scores indicate worse symptoms
