Abstract Background: To analyze the relational factors influencing the formation of cauda equina redundant nerve roots (RNRs) of the lumbar spinal stenosis.Methods: A retrospective study of 116 patients with lumbar spinal stenosis were treated in our department from January 2016 to June 2019. Magnetic resonance imaging (MRI) was performed to observe the shape and morphology of the redundant nerve roots of the cauda equina.We divided patient into (RNRs) group and non-RNRs( NRNRs) group based on the presence or absence of RNRs on sagittal T2-weighted MR. We analyzed the demographic characteristics, preoperative back pain visual analogue scale (VAS) scores ,preoperative leg pain VAS scores, and preoperative Oswestry disability index(ODI) scores, and also analyzed the rate of spondylolisthesis and ligamentum flavum hypertrophy. Simultaneously,the inter-vertebral height, intervertebral foramen height, inter-vertebral height +vertebral height, median sagittal diameter at the inter-vertebral space level(DIW-MSD),median sagittal diameter at the pedicel level(DV-MSD),ROM of the stenotic segment, were statistically analyzed for clinical and radiological significance.Results : Of a total 116 total patients,there were no statistically significant differences in either gender [RNRs group (n = 42, 18/24 female) and NRNR group (n = 74, 38/36 female)], age, BMI index, preoperative back pain VAS score , preoperative leg pain VAS score and preoperative ODI score(p> 0.05);however, there were statistically significant differences regard to the duration of symptoms and the rate of spondylolisthesis and ligamentum flavum hypertrophy (p<0.05);the inter-vertebral height,Intervertebral foramen height, inter-vertebral height+vertebral height, DIW-MSD ,ROM of the stenotic segment were also significantly different between the group (p<0.05).Conclusions:The inter-vertebral height, inter-vertebral foramen height, inter-vertebral height + vertebral height, DIW-MSD and ROM of the stenotic segment were the crucial factors related to RNRs in lumbar spinal stenosis.

Abstract Objective The aim of this study was to describe the anatomy of the nerves supplying the cervical articular process joint and to identify relevant anatomical landmarks that could aid in the ultrasound-guided location and injection of these nerves for diagnostic and therapeutic purposes. Study Design Twelve cadaveric equine necks were used. Five necks were dissected to study the anatomy of the medial branch of the dorsal ramus of the cervical spinal nerves 3 to 7. Relevant anatomical findings detected during dissections were combined with ultrasonographic images obtained in one other neck. Six additional necks were used to assess the accuracy of ultrasound-guided injections of the medial branch with blue dye. Results Each examined cervical articular process joint, except for C2 to C3, presented a dual nerve supply. The articular process joints were found to be in close anatomical relationship with the medial branch of the dorsal ramus of the cervical spinal nerve exiting from the intervertebral foramen at the same level, and with the medial branch of the dorsal ramus of the cervical spinal nerve exiting from the intervertebral foramen one level cranial to the articular process joint of interest. A total of 55 nerves were injected under ultrasonographic guidance, 51 of which were successfully stained. Conclusion The current study provided new detailed information regarding the innervation of the cervical articular process joint. The medial branches of the dorsal rami of the cervical spinal nerves were injected with an accuracy that would be of clinical value. Our study offers the foundations to develop new diagnostic and therapeutic techniques for pain management in cervical articular process joint arthropathy in horses.

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.

The Relationship

✓ The relationship of the meninges internally to the nerve roots, posterior root ganglion, and spinal nerve, and externally to the wall of the intervertebral foramen, has been investigated. The neural structures and their coverings are not attached to the foramen. Only the fourth, fifth, and sixth cervical spinal nerves have a strong attachment to the vertebral column, and this is to the gutter of the vertebral transverse process. The observations have relevance to any local lesion that may fix, deform, or otherwise affect the nerve and nerve roots to the point of interfering with their function. They may also be important to traction injuries of nerve roots.
