Previous workers have advocated hip nerve block, with local anaesthetic, in the treatment of intractable pain from osteoarthritis of the hip. In a pilot study we obtained some degree of pain relief in only six of 13 patients. A further double-blind, controlled, randomized trial was undertaken in 31 patients, comparing 0.5% Marcain and normal saline. There was no significant improvement in pain or hip movements in either group over a six-week period.
先前的研究人员主张采用局部麻醉进行髋神经阻滞，以治疗髋关节骨关节炎引起的顽固性疼痛。在一项初步研究中，我们在13名患者中只有6名获得了一定程度的疼痛缓解。我们对31名患者进行了进一步的双盲、对照、随机试验，比较了0.5%的布比卡因和生理盐水。在六周的时间里，两组患者的疼痛或髋关节活动均无明显改善。
