Occipital condyle fractures are important because they may be associated with instability of the occipitoatlantoaxial joint complex. The integrity of this complex articulation is dependent on a number of supporting ligaments, of which the tectorial membrane and bilateral alar ligaments are the most important. The tectorial membrane is a broad continuation of the posterior longitudinal ligament and is attached between the posterior body of C2 and the basiocciput *. Its main role is to limit extension at the occipitoatlantal joints. The bilateral alar ligaments are inelastic fan-shaped structures that extend from the posterolateral odontoid process to the inferomedial occipital condyles and lateral masses of C1 *. Bilateral alar ligaments limit lateral tilt and rotation in tandem. Fractures at the insertions of these ligaments are equivalent to intrinsic disruptions; occipital condyle fractures may therefore lead to instability of the craniocervical junction.
