To describe a new technique for performing fluoroscopically guided lumbar facet joint injections using an interlaminar approach and loss-of-resistance technique and to report the initial success rate of this technique in a small series of patients.
The institutional radiology database was retrospectively reviewed to identify patients who underwent fluoroscopically guided lumbar facet joint injections. Between 1 May 2014 and 31 October 2015, one radiologist attempted fluoroscopically guided lumbar facet joint injections using an interlaminar approach and loss-of-resistance technique in ten severely osteoarthritic facet joints (4 patients). Patient demographics, facet joint side and level, and whether or not an intra-articular facet joint injection was achieved were recorded.
Intra-articular injection was achieved using the interlaminar approach and loss-of-resistance technique in five facet joints.
Fluoroscopically guided lumbar facet joint injection using an interlaminar approach and loss-of-resistance technique is an alternative approach to a direct posterior facet joint injection and may be particularly useful for severely osteoarthritic facet joints, where bulky osteophytes and/or extreme curvature of the joints in the transverse plane threaten to preclude direct posterior access to the joints.
描述一种使用椎板间入路和阻力消失技术进行透视引导下腰椎小关节注射的新技术，并报告该技术在一小系列患者中的初始成功率。
回顾性分析机构放射学数据库，以确定接受透视引导下腰椎小关节注射的患者。在2014年5月1日至2015年10月31日期间，一名放射科医生尝试使用椎板间入路和阻力消失技术对10个严重骨关节炎性小关节（4例患者）进行透视引导下腰椎小关节注射。记录患者人口统计学资料、小关节的侧别和节段，以及是否成功进行关节内小关节注射。
使用椎板间入路和阻力消失技术在5个小关节中成功进行了关节内注射。
使用椎板间入路和阻力消失技术进行透视引导下腰椎小关节注射是直接后方小关节注射的一种替代方法，对于严重骨关节炎性小关节可能特别有用，在这些关节中，大量骨赘和/或关节在横断面上的极度弯曲可能会妨碍直接从后方进入关节。
