The Pathria grading system is used to classify osteoarthritis in lumbar facet joint degeneration.
Usage
This grading system is based on CT findings 1,2.
Classification
grade 1: normal CT scan with no degenerative findings
grade 2: mild joint space narrowing noted, small osteophytes
grade 3: narrowing of joint space, sclerosis and moderate-size osteophytes
grade 4: severe osteoarthritic changes, large osteophytes, narrowing of joint space, sclerosis and subchondral cysts 3
History and etymology
This classification was developed by the American radiologist Mini Pathria in 1987 4.
