Three hundred four consecutive patients with low-back pain were given epidural anesthetic and steroid injections. A prospective study demonstrated that selected patients had 87% short-term success and 34% relief of pain for as long as 6 months. No patient was cured by these injections. Needle placement during epidural injections was incorrect 25% of the time in experienced hands.
连续304例腰痛患者接受了硬膜外麻醉和类固醇注射。一项前瞻性研究表明，部分患者短期成功率为87%，疼痛缓解长达6个月的比例为34%。这些注射未能治愈任何患者。在经验丰富的医生操作下，硬膜外注射时的进针位置仍有25%的情况不正确。
