The aim of this study was to conduct a randomized, blinded,
prospective outcome study on the short-term benefits of the Kambin triangle vs.
the supraneural approach for the treatment of lumbar radicular pain. DESIGN:
Subjects with lumbar radicular pain (n = 100) were randomly assigned to undergo
transforaminal epidural steroid injection using either the Kambin triangle
approach or the supraneural approach. Primary outcomes were measured with a
verbal numeric pain scale and the Oswestry Disability Index, and the results at 2
and 12 wks after the procedure were compared between the groups. Secondary
outcomes included patient satisfaction and the incidence of complications during
the transforaminal epidural steroid injection procedure. RESULTS: For both
groups, the verbal numeric pain scale and Oswestry Disability Index scores
improved 2 wks after the injections, and this improvement was maintained through
the 12-wk follow-up. The verbal numeric pain scale, Oswestry Disability Index,
and effectiveness scores were not significantly different between groups. Neural
contact occurred in nine cases with the supraneural approach; no patients
experienced neural contact with the Kambin triangle approach. CONCLUSIONS: The
Kambin triangle approach can be used instead of the supraneural approach in cases
where it is difficult to place the needle at the anterior epidural space.
