Directly Visualized Carpal Tunnel Release via a Proximal Mini-Transverse Incision: Surgical Technique and Clinical Outcomes

<b>Background/Objectives</b>: Several complications and drawbacks have been described for the endoscopic release of carpal tunnel syndrome as well as for other traditional open and mini-open release techniques. The purpose of this study was to introduce our newly developed minimally invasive technique and report our surgical outcomes. <b>Methods</b>: Seventy-five eligible patients with carpal tunnel syndrome who underwent directly visualized carpal tunnel release via proximal mini-transverse incisions were enrolled. Turkish versions of the Quick-DASH, BCTSQ, and VAS were used to quantify the functional quality and pain intensity before surgery, at the third month, and at the final follow-up. In addition, the maximum preoperative and postoperative grip strength were evaluated. <b>Results</b>: At the three-month follow-up, there was a significant improvement in the mean VAS score and Quick-DASH score from 5.2 ± 1.4 and 27.46 ± 7 to 1.4 ± 1.1 and 10.2 ± 3.8, respectively. Additionally, significant improvements were observed in both BCTSQ components, the SSS and FSS, with mean preoperative scores of 3.6 ± 1.2 and 3.8 ± 0.9 and postoperative scores of 1.75 ± 0.6 and 2 ± 1, respectively. The Quick-DASH, BCTSQ scores, and VAS scores were further improved at the final follow-up. The mean grip strength gradually increased from 24.2 ± 8.9 kg to 28.2 ± 2.6 kg at the final follow-up. No complications occurred during or after the operation. <b>Conclusions</b>: Directly visualized carpal tunnel release via a proximal mini-transverse incision is a viable option for patients with moderate to severe CTS, as it has shown high levels of satisfaction, improved grip strength, and minimal complications.
