Anterior Cervical Discectomy and Fusion in the Ovine Model

Occipitocervical fusion
1Lake Norman Orthopedic Spine Center, Mooresville, NC, USA.
Abstract:
The evolution of occipitocervical fixation and new rigid universal screw-rod construct technology has allowed secure anchorage at each level of the occipitocervical junction with the elimination of rigid external orthoses. Rigid occipitocervical instrumentation constructs have achieved higher fusion rates and less postoperative immobilization-associated complications. Outcomes have improved compared with former nonrigid instrumentation techniques; however, with advances of rigid occipitocervical stabilization capability have come new challenges, risks, and operative techniques. A thorough understanding of the relevant cervical bony and soft tissue anatomy is essential for safe implantation and a successful outcome.

Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
Muscles that Move the Head
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...
Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...
