Abstract: This disclosure details a surgical system and method, which is permits percutaneous insertion of anchors, and is useful in orthopedic surgical procedures involving fixation of soft tissue to bone. Because the anchors may be inserted percutaneously, the anchors can be inserted into bone without requiring a skin incision and without requiring a pre-drilled bone hole. As such, use of the disclosed system and method leads to a reduction in the number of steps in a surgical procedure, which reduces surgery time, while also reducing the size of openings formed in the skin relative to other known techniques, which reduces recovery times and results in smaller and less noticeable scarring.
