Minimally invasive ultrasound-guided carpal tunnel release: preliminary clinical results. J Ultrasound Med 2018; 37: 2699-706.


To determine the intermediate-term (3-month) safety and efficacy of CTR using the SX-One MicroKnife and ultrasound guidance, including transition to a procedural room setting.


Clinical experience at the University of Michigan reporting on 18 wrists in 14 patients, including several patients with disabilities who were able to immediately use their crutches and wheelchairs. Multiple cases were performed in the office setting using only local anesthesia. The authors reported no neurovascular complications and excellent clinical outcomes.


CTR using the SX-One MicroKnife and ultrasound guidance is safe and effective and can be performed in the procedure room setting using local anesthesia (WALANT). The ability to immediately use the hands may significantly reduce post-operative disability compared to traditional CTR techniques.
