Objective To explore the correlation between the lumb ar intervertebral disc protrusion and the changes of the physical characteristic of the related auricular point surface.Methods Fifty patients with lumbar interverte bral disc protrusion were attributed to an observation group

while a control gr oup with 42 patients without lumbosacral pain in it was set up for comparison.T he subjects of both groups were observed on the intensity of tenderness and morp hological changes of vessels and skin of the area of auricular point Lumbosacral Vertebrae

and the chromatic difference of the auricular point was calculated.Results The chromatic difference of the auricular point in the observat ion gro up was（90.06±11.64） NBS

and that of the control group was（33.67±4.00） NBS

there was statistical significance between them（P<0.01）.There existed sta tisti cal differences between the two groups in the intensity of tenderness and morpho logical changes of vessels and skin of the area of Lumbosacral Vertebrae（P< 0.01）.Conclusion The characteristic changes of the appeara nce of the auricular po int

Lumbosacral Vertebrae

do have correlation with the lumbar intervertebral d isc protrusion.
