Effectiveness of Surgical Treatment in Carpal Tunnel SyndromeMini-Incision Using MIS-CTS Kits: A Cadaveric Study

Carpal tunnel syndrome (CTS) is caused by the compression of the median nerves in the wrist. Patients have painand numbness in the hands. According to the records of Songklanagarind Hospital from 2015 to 2018, of 800 patients, 196 or24.5% were treated with surgery. )e novel tool of minimally invasive surgery for carpal tunnel syndrome (MIS-CTS) wasdeveloped to improve effectiveness and safety.Purpose. )is study was performed to the effectiveness of visualization duringsurgery and the complete release of the transverse carpal ligament (TCL) and also the safety of using the MIS-CTS kits.Methods.Twenty fresh cadaveric forearms had surgery. Surgical techniques were (1) incision 15–18 mm at palmar hand; (2) the scissors andthe navigator were inserted to create working space underneath the palmar aponeurosis; (3) the visual enhancer was inserted. )evisual enhancer improves the visual field by shielding the soft tissue around the operative field; (4) the TCL was cut at the distalTCL by surgery scalpel, and then a flexible freer was used to detach the fibrous tissue from the median nerve and the TCL; and (5)the TCL cutting blade was pushed straight to cut the TCL completely from distal to proximal. TCL length was observed until thecomplete release. )e median nerve and the recurrent branch of the median nerve were observed.Results. All TCL were cutcompletely. All median nerves, recurrent branches of the median nerve, and superficial palmar arches could be observed duringthe operation, and none were injured. )is technique showed effectiveness and safety for minimally invasive carpal tunnel surgery.Conclusions. )e study found that the new device, MIS-CTS kits, along with this technique is effective for CTS release in terms ofminimally invasive open carpal tunnel surgery
