title: Epidural steroid injection for sciatica: An analysis of 526 consecutive cases with measurements and the whistle test.
abstract: The effects of epidural injections of triamcinolone acetonide and bupivacaine in the treatment of sciatica were analyzed in a retrospective series of 526 consecutive cases with measurements. A new test (the whistle test) is described. There is a paucity of measureable parameters in reports on the subject in the literature, and many are not specific or symptom-oriented to sciatica. The procedure was performed by the same operator and reviewed one week post-operatively with measurements. 491 patients (93.35%) achieved excellent to good pain relief, backed by appropriate increases of straight-leg-raise measurements. But 17 patients (3.46%) of this group required surgery later. It is concluded that epidural steroid injection is a simple, cost-effective and minimally invasive treatment for sciatica, especially in the acute. It also serves as a method for crisis intervention and as a prognosticator.
