Lumbar Facet

Posterior branches of the lumbar spinal nerves are the anatomic substrate of pain in the lower back, sacrum and the gluteal area. Such pain may be associated with various pathologies which cause pain in the posterior branches of the lumbar spinal nerves due to entrapment, mechanical irritation or inflammatory reaction and/or degeneration. The posterior branches are of significant functional importance, which is related to the function of the structures they supply, including facet joints, which are the basic biomechanical units of the spine. Low back pain caused by facet joint pathology may be triggered e.g. by simple activities, such as body rotations, unnatural positions, lifting heavy weights or excessive bending as well as chronic overloading with spinal hyperextension. Pain usually presents at the level of the lumbosacral junction (L 5 -S 1 ) and in the lower lumbar spine (L 4-5 , L 3-4 ). In the absence of specific diagnostic criteria, it is only possible to conclude that patients display tenderness at the level of the affected facet joint and that the pain is triggered by extension. Differential diagnosis for low back pain is difficult, since the pain may originate from various structures. The most reliable method of identifying Lumbar Facet Syndrome has been found to be a positive response to an analgesic procedure in the form of a block of the medial branch or intraarticular injection. There appear to be good grounds for conducting further studies and developing unequivocal diagnostic tests.

This communication is the fifth in a series of six publications describing acupuncture points by anatomic nomenclature. This article describes acunpuncture points in the lumbar region of the posterior body wall, the inguinal and pelvic regins of the lower abdomen, and the medial surface of the thigh and leg. Acunpuncture points in these regions are generally established by anatomic features of the lumbar spinal nerves. Nerve branches of the posterior primary rami of the lumbar spinal nerves and the lumbar plexus provide the anatomic basis for acunpuncture points in these regions and are used to name the points accordingly.

Cyst Development

Object Although many cases of primary intraspinal facet cysts in the lumbar spine have been reported, there have only been a few reports of postoperative intraspinal facet cysts in the lumbar spine. The purpose of this study was to investigate the prevalence and clinical features of postoperative intraspinal facet cysts in the lumbar spine. Methods Data from 81 patients undergoing microendoscopic posterior decompression to treat lumbar spinal stenosis were reviewed. The development of a postoperative intraspinal facet cyst was observed using MR imaging during 1 year after surgery. If the patient demonstrated a postoperative intraspinal facet cyst, additional MR imaging was performed to evaluate the natural course of the cyst. Furthermore, the authors conducted a comparative evaluation to identify the factors associated with the causes of cyst development. Results A postoperative intraspinal facet cyst developed in 7 patients (8.6%) during 1 year after surgery. Spondylotic spinal stenosis, degenerative spondylolisthesis, and degenerative scoliosis were revealed before surgery in 2, 4, and 1 patient, respectively. In 5 patients, the cysts developed within 3 months after surgery. Although 3 patients exhibited symptoms caused by cyst development, all symptoms were relieved by conservative treatment. On radiographic evaluations, postoperative segmental spinal instability, including a progression of spondylolisthesis and disc degeneration, was revealed in 6 (86%) of the 7 patients. Spontaneous regression of the cysts was observed in 5 (71%) of these 7 patients. On comparative evaluation of patients with and without postoperative intraspinal facet cysts, the presence of segmental spinal instability before surgery (including degenerative spondylolisthesis) and the appearance of postoperative segmental spinal instability were related to the development of the cysts. Conclusions The prevalence of postoperative intraspinal facet cysts, including asymptomatic cysts, was 8.6% during 1 year after decompression surgery for lumbar spinal stenosis. The development of postoperative intraspinal facet cysts was related to the presence of segmental spinal instability before surgery (including degenerative spondylolisthesis) and postoperative segmental spinal instability, including a progression of spondylolisthesis and disc degeneration after surgery. A postoperative intraspinal facet cyst, which can be expected to regress spontaneously with a probability > 50%, should be recognized as one of the postoperative complications of decompression surgery for lumbar spinal stenosis.
