Five cases of groin pain that refused deliniation and had NO back pains. They all turned out to be L4/5 or L5/S1 disc pain found on discogram/discoblock. They all got relief with anterior intrabody fusion.

- started wtih 212 cases of obscure groin pains
- zeroed in on cases with ONE level disc degeneration
- 10 cases were selected; there was no back or radicular pains
- Hip injection did not give any temporary relief so eliminated as cause. Prior xrays/mri were normal
- 5/10 had aggravation with discogram and relief with discoblock. – These had surgery
- L4/5 was the level in three; L5/S1 in two.
- Fusion relieved pain in all cases
- There conclusion – It is important to consider discogenic groin pain [even] if the patients do not show low back pain.Conclusion – without access to discogram/discoblock unlikely to make a decent diagnosis… Wonder if pamidronate or antibiotics would help…
