NCT01972165

Brief Summary

A few studies have shown that the mini-incision release technique decreases the pathologic swelling of the median nerve at the inlet of the carpal tunnel and increases the flattening ratio of the median nerve in the carpal tunnel. However, it is unknown whether the endoscopic release technique similarly reverses these pathological changes in the median nerve along the carpal tunnel in patients with CTS compared with the mini-incision release. Investigators therefore conducted the current study to compare the subjective outcomes and US-measured morphological changes in the median nerve in patients with CTS who received either mini-incision or endoscopic release. Investigators hypothesized that (1) subjective outcomes, as assessed by both the Boston Carpal Tunnel Questionnaire (BCTQ) symptom/function scores and the DASH scores, would be similar 24 weeks after either mini-incision or endoscopic carpal tunnel release; (2) changes in the morphology of the median nerve at each level of the carpal tunnel, as measured under high-resolution US, would be similar 24 weeks after either mini-incision or endoscopic carpal tunnel release; and (3) morphological changes would be correlated with improvements in subjective outcomes 24 weeks after mini-incision or endoscopic carpal tunnel release.

Outcome Measures

Primary Outcomes (1)

  • Change of the Boston Carpal Tunnel Questionnaire (BCTQ)

    The BCTQ is a disease-specific status scale that incorporates both a symptom severity scale and a functional scale. The symptom severity scale (BCTQ-S) is comprised of eleven items that address the severity, frequency, and duration of symptoms, whereas the functional status scale (BCTQ-F) is comprised of eight questions that assess the difficulty of performing eight daily tasks. Each question offers five possible responses of increasing severity, which are scored from 1 (none) to 5 (most severe); the mean values of all the items in the BCTQ were calculated.

    preoperatively and 24 weeks post-operation

Secondary Outcomes (1)

  • Change of the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire

    preoperatively and 24 weeks post-operation

Other Outcomes (1)

  • Change of Ultrasonographic median nerve morphology
