View Patent ↗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.
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.
6. The method of claim 1 , wherein the bone is a skeletal bone.
7. The method of claim 1 , further comprising:
aligning the connector along the at least one bone, after the step of securing the anchoring screw to the bone.
