-Lumbosciatica is a common condition which is associated with significant pain and disability. The aim of the present study was to examine the efficacy of interlaminar epidural corticosteroid infiltration in the treatment of lumbosciatic pain. We evaluated retrospectively sixty patients with lumbosciatic pain that a sequential interlaminar epidural administration of 40 mg methylprednisolone in 7 mL bupivacaine 0.25% was administered. Each patient was interviewed and asked about the pain according to visual analogue scale (VAS) and the level of disability according to World Health Organization previously of the epidural corticosteroid infiltration and, 1 and, 6 months after starting therapy. Independently of the initial VAS value, all patients decreased their pain score after one and six months of follow-up (p<0.05). However, only the patients with a low grade of disability showed an improvement after the treatment (p<0.05). No side effects were reported after epidural corticosteroid injections. In conclusion, interlaminar epidural corticosteroid injection in association with local anesthetic may be useful, at least for six months, as additional therapy of the conservative management of lumbosciatic pain.KEY WORDS: epidural corticosteroid, herniated disc, pain, visual analogue scale. Injeção epidural interlaminar de corticóide no tratamento da dor da lombociatalgia: análise retrospectivaRESUMO -A lombociatalgia é condição clínica associada à dor intensa e alterações funcionais. O objetivo do presente estudo foi examinar a eficácia da infiltração de corticóide pela via epidural interlaminar no tratamento da dor da lombociatalgia. Foram avaliados, retrospectivamente, sessenta pacientes com lombociatalgia que foram submetidos à administração epidural interlaminar, em sequência, de 40 mg de metilprednisolona e 7 mL de bupivacaína a 0,25%. Os pacientes foram avaliados em relação à dor de acordo com a escala visual analógica (EVA) e o grau de comprometimento funcional de acordo com a Organização Mundial de Saúde antes e, uma e, seis meses após o início do tratamento. Independentemente do valor inicial da EVA, todos os pacientes diminuíram o escore de dor após um e, seis meses de acompanhamento (p<0.05). Entretanto, apenas os pacientes com baixo grau de comprometimento funcional apresentaram melhora após o tratamento (p<0.05). Não foram observados efeitos colaterais após as injeções de corticói-de epidural. Concluindo, a injeção epidural interlaminar de corticóide em associação com anestésico local pode ser benéfico, por pelo menos seis meses, como terapia coadjuvante no tratamento conservador da dor da lombociatalgia. PALAVRAS-CHAVE: corticóide epidural, hérnia de disco, dor, escala visual analógica.
