UnlabelledThe seven Criteria of Cochin (CC), clinical descriptive criteria of low back pain (LBP), have been shown to be able to select patients whose LBP would respond well to facet joint anesthesia.AimTo determine if these seven criteria set are able to select patients with significant relief of LBP after corticosteroid facet joint injections (CFJI).MethodsNinety-one patients with chronic LBP were included in a positive group (PG) or a negative group (NG) according to the number of the positive CC. Patients placed in the PG had five or more of the positive CC and those in the NG had less than five of the positive CC. All of them received CFJI on day 0 (D0). The severity of LBP and leg pain, disability and CFJI effect were evaluated on a self-questionnaire on D0, D2, D8 and D30.ResultsTwo hundred and seventeen CFJI were performed (mean 2.1 per patient). Compared to the initial values we observed a significant reduction of the LBP at D2, D8 and D30 in both the groups (P < 0.05), a significant augmentation of the leg pain at D30 in the GN (P < 0.05) and a significant improvement of the Quebec back pain disability scale (QBDS) at D8 and D30 in the PG (P <0.05). Compared to the NG values, the PG had a significant higher global estimation of the efficacy of the treatment (P < 0.05) and a significant lesser intensive LBP (P <0.05) on D2, D8 and D30, a significant lesser intensive leg pain (P < 0.05) on D30, and a tendency to a more important reduction of the QBDS on D8 and D30 (P > 0.05).ConclusionCC seems to be an effective test to select patients whose LBP would respond well to CFJI.
