Background: Cervical facet joint needling and stimulation is useful for the management of cervical facet arthropathy, but a direct needling of the joint may injure the capsule and cause post-needling pain.We developed a new approaching technique for cervical facet joint needling and stimulation.
Methods: We retrospectively reviewed medical records of 24 patients with cervical facet arthropathy who underwent facet joint needling and stimulation through oblique posterior approach.Under ultrasonographic guidance, a specially designed dry needle (Ahn’s needle) was inserted at midline of posterior neck and advanced obliquely to posterior and lateral side of facet joint.The procedure was completed when a marked reduction in resistance was felt at the tip of the needle.Follow-ups using the numeric rating pain scale (NRS) and the rate of self-rated improvement were conducted at three weeks and about three months after last treatment by telephone interview.
Results: Among them, 23 patients were enrolled.The average of NRS decreased from 6.8 ± 3.0 to 2.7 ± 3.0 at 3 weeks and to 2.9 ± 2.0 at 3 months after the last treatment (P ＜ 0.05).The average rate of self-rated improvement was 63.7 ± 7.2 and 61.6 ± 3.0% at 3 weeks and 3 months after the last treatment respectively.
Conclusions:Our result suggested that this technique for dry needling around cervical facet joint under ultrasound guidance is one of the successful options to treat neck pain derived from facet joint.(
