Denis Classification
The Denis Classification (pronounced: den-ee clas-si-fi-ca-tion) is a system used in the field of medicine to categorize fractures of the spine. It was developed by Francis Denis, a renowned orthopedic surgeon.
Etymology
The Denis Classification is named after its creator, Francis Denis. The term "classification" comes from the Latin word "classis", which means "class" or "group", and the suffix "-fication" from the Latin "facere", meaning "to make" or "to do".
Description
The Denis Classification divides the spine into three columns: the anterior column, the middle column, and the posterior column. Each column is associated with specific anatomical structures and fracture patterns. This classification system is used to determine the stability of spinal fractures and guide treatment decisions.
Anterior Column
The anterior column of the Denis Classification includes the anterior longitudinal ligament and the anterior half of the vertebral body and intervertebral disc.
Middle Column
The middle column consists of the posterior half of the vertebral body, the posterior longitudinal ligament, and the intervertebral disc.
Posterior Column
The posterior column includes the facet joints, lamina, spinous process, and the ligamentum flavum.
