Abstract
ObjectivesTo evaluate the feasibility and 6 months clinical result of sectioning of the transverse carpal ligament (TCL) and median nerve decompression after ultra-minimally invasive, ultrasound-guided percutaneous carpal tunnel release (PCTR) surgery.MethodsConsecutive patients with carpal tunnel syndrome were enrolled in this descriptive, open-label study. The procedure was performed in the interventional radiology room. Magnetic resonance imaging was performed at baseline and 1 month. The Boston Carpal Tunnel Questionnaire was administered at baseline, 1, and 6 months.Results129 patients were enrolled. Significant decreases in mean symptom severity scores (3.3 ± 0.7 at baseline, 1.7 ± 0.4 at Month 1, 1.3 ± 0.3 at Month 6) and mean functional status scores (2.6 ± 1.1 at baseline, 1.6 ± 0.4 at Month 1, 1.3 ± 0.5 at Month 6) were noted. Magnetic resonance imaging showed a complete section of all TCL and nerve decompression in 100% of patients. No complications were identified.ConclusionsUltrasound-guided PCTR was used successfully to section the TCL, decompress the median nerve, and reduce self-reported symptoms.
Highlights
Carpal tunnel syndrome, which is a common neuropathy, is caused by the transverse carpal ligament (TCL) compressing the median nerve at the base of the palm
Consecutive patients with carpal tunnel syndrome were enrolled in this descriptive, open-label study
Meta-analyses have underscored the impact of low visibility by showing that risk of transient nerve damage is higher with ECTR than with Open carpal tunnel releases (OCTR) [3, 4]
Summary
Carpal tunnel syndrome, which is a common neuropathy, is caused by the transverse carpal ligament (TCL) compressing the median nerve at the base of the palm. Most often, when nonsurgical methods, such as rest, splinting, physical therapy, and corticosteroid injections, do not alleviate symptoms sufficiently, a surgical release of the median nerve is achieved by sectioning the TCL. Open carpal tunnel releases (OCTR) have been performed successfully for many years [1]. These procedures are, associated with 60–80 mm scars, lengthy recovery periods (25 days), and a complication rate of *1% [2]. Meta-analyses have underscored the impact of low visibility by showing that risk of transient nerve damage is higher with ECTR than with OCTR [3, 4].
