Cervical Spine Injuries, Fractures and Whiplash - Occipital Condyle Fracture

Occipital condyle fracture
Occipital condyle fracture. The fragment was avulsed by the (intact) alar ligament. On the plain radiograms this fracture was barely visible and was only detected at second–look evaluation. The avulsed fragment is displaced posteriorly and medially, embedding medium fills the wide fracture gap. Note the tom posterior joint capsule and muscle ruptures under the posterior arch of the atlas. The vertebral artery and the underlying C1 nerve are surrounded by wide venous sinuses. In the atlanto–axial joint the posterior meniscoid and the joint capsule are tom, pulling the C2 nerve into the joint space.
