System and method for spine stabilization using resilient inserts

A method of assembling a spinal stabilization system, comprising:

• engaging a bone fastener of a bone fastener assembly to a bone, wherein the bone fastener assembly includes the bone fastener, a housing, a first resilient insert insertable into the housing, and a second resilient insert insertable into the housing;
• advancing the first resilient insert within the housing toward a second end of the housing with the head of the bone fastener positioned in a channel of the first resilient insert to secure the housing to the bone fastener;
• and
• advancing the second resilient insert within the housing toward a first end of the housing with a rod positioned in a channel of the second resilient insert to secure the housing to the rod.

A method for coupling a rod to a portion of a spine, comprising:

• advancing a bone fastener into a vertebral body, wherein the bone fastener includes a head and a threaded shank extending from the head;
• positioning a first resilient insert onto the head of the bone fastener;
• positioning the first resilient insert into a first end of a housing;
• positioning a second resilient insert onto a rod;
• positioning the second resilient insert into a second end of the housing;
• advancing the first resilient insert within the housing toward the second end of the housing to secure the housing to the bone fastener;
• and
• advancing the second resilient insert within the housing toward the first end of the housing to secure the housing to the rod.
