ROD CONTOURING APPARATUS AND METHOD FOR PERCUTANEOUS PEDICLE SCREW EXTENSION

摘要

The invention provides a system for configuring or selecting one or more implants and for implanting the implants proximate a bone in the body of a patient. The system comprises a first cannula having a distal end configured to be positioned within the body of the patient proximate a first anatomic point through which the one or more implants are to pass, such that a proximal portion of the first cannula protrudes above the skin of the patient. The system also comprises a second cannula having a distal end configured to be positioned within the body of the patient proximate a second anatomic point through which the one or more implants are to pass, such that a proximal portion of the second cannula protrudes above the skin of the patient. The system further comprises a first simulation member attachable to the proximal portion of the first cannula so as to provide a first projected point outside the body, and a second simulation member attachable to the proximal portion of the second cannula so as to provide a second projected point outside the body. The first and second simulation members are configured to receive the one or more implants to facilitate configuration or selection of the one or more implants based on locations of the first and second projected points. The present invention also provides a method for configuring or selecting one or more implants and percutaneously implanting the implants in a body of a patient.
