ABSTRACT:
A method of implementing an endoscopic surgical procedure on a patient, and more particularly, a novel and unique technique of performing a uniportal palmar subligmentous endoscopic carpal tunnel release. Moreover, also disclosed is a unique endoscopic surgical instrument adapted to be employed in the implementation of the foregoing method of endoscopically effecting the carpal tunnel release. This surgical procedure only requires the formation of a single and relatively small entry portal or incision in the palm proximate the distal side of the flexor retinaculum, thereby reducing any postoperative symptoms of the patient with only a cosmetically appealing scar formed on the palm, while eliminating the need for a second portal or incision proximate the wrist of the patient. Moreover, the endoscopic instrument employed in implementing the inventive method utilizes a unique cutting device which is mounted on a scope insertable through a cannula which has been initially inserted to extend beneath the flexor retinaculum from the distal side of the flexor retinaculum.
