The present invention provides a method for stabilizing a fractured bone. The method includes positioning an elongate rod in the medullary canal of the fractured bone and forming a passageway through the cortex of the bone. The passageway extends from the exterior surface of the bone to the medullary canal of the bone. The method also includes creating a bonding region on the elongate rod. The bonding region is generally aligned with the passageway of the cortex. Furthermore, the method includes positioning a fastener in the passageway of the cortex and on the bonding region of the elongate rod and thermally bonding the fastener to the bonding region of the elongate rod while the fastener is positioned in the passageway of the cortex.
1. A tissue repair system comprising: a polymeric intramedullary rod having an inner core and an outer surface, wherein the outer surface of the intramedullary rod includes a bonding region free of through holes, wherein the inner core is fabricated from a first material and the outer surface is fab
1. A tissue repair system comprising: a polymeric intramedullary rod having an inner core and an outer surface, wherein the outer surface of the intramedullary rod includes a bonding region free of through holes, wherein the inner core is fabricated from a first material and the outer surface is fabricated from a first portion of PEEK;a fastener having a leading portion and a trailing end opposite the leading portion, the leading portion including a second portion of PEEK, wherein at least a portion of the second portion of PEEK at the leading portion is configured to be ultrasonically bonded to the first portion of PEEK on the bonding region on the outer surface of the intramedullary rod upon application of ultrasonic energy to the trailing end of the fastener; andan end effector configured to apply the ultrasonic energy to the trailing end of the fastener. 2. The system of claim 1 wherein the bonding region includes a roughened surface on the polymeric intramedullary rod. 3. The system of claim 1 wherein the bonding region includes an indentation in the polymeric intramedullary rod. 4. The system of claim 1 wherein the bonding region of the intramedullary rod includes an indentation that extends only partially into the polymeric intramedullary rod. 5. The system of claim 1 wherein at least one of the fastener and the first material of the polymeric intramedullary rod is metallic. 6. The system of claim 1 wherein the fastener is free of a trailing head or cap. 7. The system of claim 1 wherein the leading portion of the fastener includes a shape that is at least one of a prong, Morse taper, wedge, and angled taper. 8. The system of claim 1 wherein a sensor is associated with the end effector, the sensor operative to indicate a pressure applied to the fastener by the end effector during the application of ultrasonic energy. 9. The system of claim 1 wherein a sensor is positioned proximate the leading portion of the fastener, the sensor operative to indicate a pressure applied to the leading portion of the fastener by the end effector during the application of ultrasonic energy. 10. The system of claim 1 wherein a sensor is associated with the end effector, the sensor operative to indicate a change in shape of the fastener during the application of ultrasonic energy, whereby the application of ultrasonic energy is changed based on a change in shape of the fastener indicated by the sensor. 11. The system of claim 1 wherein a sensor is associated with the end effector, the sensor operative to communicate feedback to vary, start, and stop application of ultrasonic energy. 12. The system of claim 1 wherein one of the end effector and the trailing end of the fastener is provided with a recess, and the other end of the end effector and the trailing end of the fastener is provided with an extension shaped to mate with said recess. 13. A tissue repair system comprising: a polymeric implant having an inner core and an outer surface, wherein the outer surface of the implant includes a bonding region including a first portion of PEEK;a fastener having a leading portion and a trailing end opposite the leading portion, the leading portion including a second portion of PEEK, wherein at least a portion of the second portion of PEEK at the leading portion is configured to radially expand and be ultrasonically bonded to the first portion of PEEK of the bonding region of the outer surface of the polymeric implant upon application of ultrasonic energy to the trailing end of the fastener without the fastener being positioned through the outer surface of the implant; andan end effector configured to apply the ultrasonic energy to the trailing end of the fastener. 14. The system of claim 13 wherein the polymeric implant is an intramedullary rod. 15. The system of claim 13 wherein at least one of the fastener or the inner core of the polymeric implant is metallic.
