OCCIPITAL FIXATION ASSEMBLY, SYSTEM AND METHOD FOR ATTACHING THE SAME

摘要

An occipital fixation assembly is provided. The occipital fixation assembly includes a first mounting plate configured for placement within a sinus cavity adjacent a rear portion of a skull of a patient. A threaded post extends from the first mounting plate. A coupling member includes an aperture configured to receive the threaded post therethrough. The coupling member includes an offset extension configured to support a surgical rod thereon. A fixation nut configured to threadably engage the threaded post of the first mounting plate is rotatable about the threaded post and translatable therealong. The fixation nut is rotatable with respect to the first mounting plate and the coupling member such that rotation of the fixation nut in a predetermined direction brings the first mounting plate and the coupling member toward one another and into secured engagement with the skull of a patient.

主权项

1. A method for attaching an occipital fixation assembly for subsequent attachment of a surgical rod thereon, comprising:
creating an aperture within a sinus cavity adjacent a rear portion of a skull of a patient; positioning a first mounting plate of an occipital fixation assembly through the aperture created within the sinus cavity; attaching a coupling member of the occipital fixation assembly to a threaded post of the first mounting plate; positioning a fixation nut about the threaded post and, subsequently, rotating the fixation nut in a predetermined direction thereabout such that the first mounting plate and the coupling member move toward one another and into secured engagement with the skull of the patient; and coupling a surgical rod to the coupling member.
