Nerve root blocks in the treatment of lumbar radicular pain. A minimum five-year follow-up.

この研究はハイインパクトの可能性があります。 OEのAI駆動型ハイインパクト指標は、論文が掲載されたジャーナルと論文自体の科学的内容の両方からのシグナルを統合することで、論文が持つ可能性の高い影響力を推定します。 最先端の自然言語処理を用いて開発されたOEハイインパクトモデルは、ジャーナルのインパクトファクターのみよりも、研究の将来の引用実績をより正確に予測します。 これにより、臨床的に意義のある研究をより早く認識することが可能になり、読者は将来の診療を形成する可能性が最も高い論文に集中することができます。

21 patients with lumbar radiculopathy due to a herniated nucleus pulposus or spinal stenosis were included in a study investigating the effects of selective nerve root blocks in the lumbar spine on preventing the need for operative treatment. Patients had been randomized in a prior study, that included 55 patients, to receive bupivacaine alone or bupivacaine and betamethasone. 29 of these patient avoided surgey and 21 on were available to be followed up at 5 years. After 5 years, there was no difference between the two groups for the proportion of patients who did not require surgery. 17 of 21 patients receiving a nerve root injection who did not require surgery at 1 year continued to 5 years without needing operative intervention. All patients who did not receive surgery at 5 years demonstrated significant improvement in neurological symptoms and back pain.
