Mechanical low back pain secondary to degenerative facet joint changes is a common reason for referral to pain clinics. When these changes cause encroachment into the intervertebral foramen, radicular pain may result. While pulsed radiofrequency of the dorsal root ganglion can be used in this setting, the anatomic deformity may make the transforaminal approach difficult. We report a case where a trans-facet approach was used successfully and describe the technique.
继发于小关节退变的机械性下腰痛是转诊至疼痛门诊的常见原因。当这些改变导致椎间孔受压时，可能会引起根性疼痛。虽然在这种情况下可使用背根神经节脉冲射频，但解剖结构畸形可能会使经椎间孔入路变得困难。我们报告了一例成功采用经小关节入路的病例并描述了该技术。
