Conditions

Carpal Tunnel Syndrome Bilateral

Brief summary

To compare the incisionless thread carpal tunnel release with the standard mini-open carpal tunnel release (standard of care) in patients with bilateral carpal tunnel syndrome. Patients with bilateral CTS will have one side released with incisionless thread carpal tunnel release and the contralateral side released with the mini-open carpal tunnel release. The investigators hypothesize that the incisionless thread carpal tunnel release (TCTR) will be no different than the standard mini-open release (MOR) with regard to symptom improvement and safety and will be less painful, result in quicker return to work and will be less costly.

Interventions

PROCEDURECarpal Tunnel Procedure (open)

Patients with bilateral CTS will have one side released with incisionless thread carpal tunnel release and the contralateral side released with the mini-open carpal tunnel release.

Inclusion criteria

* A diagnosis of bilateral CTS with symptoms including pain, paresthesia's, and weakness of the hand in the median nerve distribution for minimum of 3 months * Willingness to undergo bilateral carpal tunnel surgical treatment with one side having the TCTR and the other a mini open carpal tunnel release * Age 18-65 years of age * Clinical examination findings (compression test, Tinels, Phalens, etc) consistent with carpal tunnel syndrome. * Persistence of symptoms after 6 weeks of conservative treatment such as splinting, activity modification, and/or injection therapy. * Electromyographic evidence of mild, moderate, moderately severe, or severe median nerve neuropathy at the wrist * Able and willing to complete all follow-up appointments

Exclusion criteria

* Previous CTS surgical release on any of their hands * Diabetes mellitus * Hypothyroidism * Significant Hand arthritis (rheumatologic or osteoarthritis) * Pregnancy * Electromyographic evidence of any condition other than CTS affecting the hand * Workman's compensation

Design outcomes

Primary

MeasureTime frameDescription
Change in Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) functional scoreChange from Baseline to 12 monthsMeasured on a symptom severity scale from 1 to 5, where 1 is normal and 5 is very serious/continued/difficult
Visual analog pain scaleChange from Baseline to 12 monthsPain that participant is currently experiencing the in the hand or risk(0-100)
Strength testing of grip and pinchChange from Baseline to 12 monthsUse dynameters and pinch meters
Disability of the Arm Shoulder Hand DASHChange from Baseline to 12 monthshe disabilities of the arm, shoulder and hand (DASH) questionnaire is a self-administered region-specific outcome instrument developed as a measure of self-rated upper-extremity disability and symptoms. The DASH consists mainly of a 30-item disability/symptom scale, scored 0 (no disability) to 100. The main purpose of this study was to assess the longitudinal construct validity of the DASH among patients undergoing surgery. The second purpose was to quantify self-rated treatment effectiveness after surgery.
