This study maps canine extruded disc herniation (EDH) using a geographical information system (GIS). GIS effectively visualizes EDH locations within the vertebral canal, aiding spatial analysis of this common canine pathology.
Area of Science:
- Veterinary Medicine
- Comparative Pathology
- Geospatial Analysis
Background:
- Disc herniation is a frequent vertebral column pathology in dogs.
- Understanding the spatial distribution of extruded disc herniation (EDH) is crucial for diagnosis and treatment.
Purpose of the Study:
- To develop a geographical information system (GIS)-based vertebral canal (VC) map.
- To enable spatial evaluation of extruded disc herniation (EDH) in dogs.
Main Methods:
- Utilized ArcGIS® to create 2D and 3D VC maps.
- Analyzed 142 canine computed tomographies (2005-2013) for EDH location and direction.
- Generated choropleth maps to illustrate EDH frequency and spatial patterns.
Main Results:
- Most EDHs occurred in cervical and transitional (thoraco-lumbar, lumbo-sacral) regions.
- EDHs were predominantly located in ventro-cranial and ventro-central VC polygons.
- GIS mapping effectively highlighted EDH distribution and directional patterns.
Conclusions:
- GIS is a valuable tool for analyzing canine EDH.
- Further research into biomechanical aspects of EDH patterns is warranted.
