A fixation device and method stabilizers at least one bone of a patient. The device includes a connector with one end defining a screw fixator configured to receive an anchoring screw and a securing cap configured to maintain the screw in the screw fixator.

Claims (21)

1. A method for stabilizing at least one bone of a patient, comprising:

securing a bone anchor in a first bone portion of a patient, the bone anchor comprising a head portion having an aperture;

inserting an anchoring screw into a fixation device, the fixation device comprising:

a connector comprising a first end and a second end, the first end defining a screw fixator, wherein the screw fixator defines an opening configured to receive an anchoring screw, the anchoring screw comprising:

a head adapted to fit at least partially within the screw fixator; and

a securing cap;

inserting the second end of the connector through the aperture in the bone anchor;

threading the anchoring screw into a bone of the patient;

advancing the anchoring screw so that the head is recessed within the screw fixator;

securing the securing cap to the screw fixator to secure the anchoring screw; and

permitting the connector to move relative to the bone anchor while maintaining a portion of the connector inside that aperture.

2. The method of claim 1 , further comprising:

providing a secondary screw;

securing the secondary screw to at least one bone of a patient; and

securing the second end of the connector to the secondary screw.

3. The method of claim 2 , wherein the anchoring screw is secured to a sacral bone and the secondary screw is secured to a lumbar vertebra.

4. The method of claim 3 , further comprising a step of securing the connector to the bone of a patient using more than one secondary screw.

5. The method of claim 1 , wherein the one bone is a vertebra.
