Surgical stabilization of cervical spinal fractures using methyl methacrylate. Technical considerations and long-term results in 52 patients

Occipitocervical Fusion

Occipitocervical fusion is a surgical technique in continuous evolution due to the innovation of devices, operative and instrumentation techniques. The aetiologies responsible for occipitocervical instability are trauma, neoplastic disease, metabolic disease or congenital disease. A variety of stabilization techniques are currently available depending on the type of patient and surgeon's experience. Each of these techniques requires thorough knowledge of the anatomy of the craniovertebral junction.

Evolution of posterior cervical and occipitocervical fusion and instrumentation

The past several decades have been the setting for a remarkable evolution of spinal instrumentation technology. The advancements that have been made have allowed previously complex disorders of the cervical spine, the atlantoaxial articulation, and the occipitocervical junction to be managed more effectively with direct methods of internal fixation and arthrodesis. This has resulted in improvements in patient outcomes and fusion success rates. The improved strength of instrumentation constructs allows minimal, if any, external bracing, obviating the need for a halo orthosis in many cases. In this paper the authors review key events that have occurred in neuroimaging, biomechanical testing, and the development of fusion and instrumentation constructs.

Spinal fracture or luxation

Spinal trauma is a common cause of spinal cord dysfunction in dogs and cats. When the spine is injured by exogenous injury, the impact often results in vertebral fracture or luxation. As each injury is unique, treatment guidelines have to be individualized to the animal. This article reviews the clinical management including surgical and nonsurgical treatments for animals with vertebral fracture/luxation.
