Tratamiento con acupuntura y moxibustión del síndrome poslaminectomía. Caso clínico

Failed back surgery syndrome is a common post-surgical complication which leads to chronic low back pain with great clinical and financial repercussions. The treatment possibilities include a great variety of techniques and drugs, despite this being one of the main causes of a very difficult to treat lumbar pain. There is increasing solid evidence that acupuncture may be a useful complement to conventional treatment for treating low back pain. A case is presented of a 37 year-old patient surgically intervened 2 years ago for L4-L5 arthrodesis, with subsequent intervention 1 year ago to remove the osteosynthesis material. There was a persistent uncontrolled post-laminectomy syndrome with a dysesthetic scar despite treatment with weak opiates and anticonvulsants, which was treated adequately with sessions of acupuncture and moxibustion. A magnetic resonance imaging scan was performed as a complementary test, in which post-surgical changes could also be seen in the posterior lumbar region, disc dehydration in L5-S1, and degenerative arthrosis of the small interapophyseal lumbar joints. An electro-neurophysiological study showed a change in the somesthetic evoked potentials performed in the left lateral femoral-cutaneous nerve, compatible with an axonal neuropathy of that nerve. Treatment was given in 10 sessions over 5 weeks, in with a biphasic treatment of 40 min being performed in each of them. The scar area was treated first and then the low back pain, moxibustion was performed on both with Artemis smoke and a pecking technique. The pain was controlled, going from a initial VAS score of 8 to 0 at the end of treatment. At the follow-up review at 6 months it was still 0 on the VAS scale.
