OBJECTIVE: To explore the relationship between the distributions of posterior ramus of spinal nerve (PRSN) and locations of acupoint in low back through anatomical observation. METHODS: The regional anatomy was performed at five corpses to observe the distribution of erector spinae muscle and PRSN in areas of Jiaji points and back-shu points in low back. RESULTS: The T12, L1, L2, L3 and L4 PRSN distributed on both sides of the spine; the medial branches of PRSN travelled between spinalis thoracis muscle and longissimus thoracis muscle, while the lateral branches of PRSN travelled between longissimus thoracis muscle and iliocostalis lumborum muscle...

BACKGROUND: Pain of lumbar facet-joint origin is a common cause of low back pain in adults and may lead to chronic pain and disability, with associated health and socioeconomic implications. The socioeconomic burden includes an inability to return to work resulting in loss of productivity in addition to direct and indirect health-care utilisation costs. Lumbar facet-joints are paired synovial joints between the superior and inferior articular processes of consecutive lumbar vertebrae and between the fifth lumbar vertebra and the sacrum...

A 78-year-old male experienced right lower eyelid ectropion following right facial trauma from a fall 5 years ago, for which he underwent autogenous palmaris longus tendon graft surgery at another clinic. Recurrence was noted 3 years after surgery. On first examination, there was outward turning of the lateral half of the right lower eyelid margin. We performed a lateral tarsal strip procedure with removal of the graft. Intraoperatively, the lateral part of the graft was located along the inferior tarsal border, whereas the medial part was located on the tarsal surface...

In 2011, national diagnostic reference levels (DRLs) were proposed for pain management fluoroscopic procedures in Belgium. The primary goal of this work is to compare the dose area product values (DAP) recorded at the Saint-Luc University Hospital to these DRLs. From 2012 to 2015, 7664 interventional pain management procedures (4740 epidural, 2097 medial branch and 807 transforaminal infiltrations) were performed. Uni/multivariable analyses were done regarding the influence of different factors. The fluoroscopy duration and the DAP are lower to the DRLs (p < 0...

The origin of the posterior scrotal nerve is considered to be the bilateral pudendal nerves but the course to the midline is still obscure. Using 5 late-stage human male fetuses, we identified the single nerve through the intramuscular midline septum of the bulbospongiosus and the bilateral nerves along the left and right sides of the septum. Thus, the posterior scrotal nerve showed a variation: a single midline trunk or bilateral nerves. Branches of the bilateral pudendal nerves ran medially between the muscle and Cowper's gland and, at the midline area, they joined or associated closely...

Introduction: The Vastus Medialis (VM) muscle divides into two parts, proximal Vastus Medialis Longus (VML) and distal Vastus Medialis Obliquus (VMO). The VMO originates from the tendon of adductor magnus and insert into the medial border of patella and these fibers are nearly horizontal. It exerts medial force vector to counter the lateral force vector of Vastus Lateralis (VL) hence the VM presents a biomechanical advantage over the VL. The functional importance of VML and VMO is well explained but the anatomical evidence of separate identity of VMO is lacking...

This research is a study about the arterial vascularization of pelvic cavity and pelvic limb in pampas deer. For this study, 25 dead animals were used. The vascularization of the organs was investigated using a latex injection technique. Two animals were injected in the common carotid artery with contrast to cardiac angiography, and then, radiographs were taken. The aorta showed the two external iliac arteries, and after a short course, the aorta ended in two internal iliac arteries. The median sacral artery was originated from the dorsal surface cranially to the emergence of the internal iliac arteries...

OBJECTIVES: High-resolution ultrasonography (US) can play an important role in studying nerves, as it has several advantages. Entrapments of distal tibial nerve branches can be mapped out or diagnosed with selective anesthetic blocks, and US can guide therapeutic procedures, such as radiofrequency ablation and selective infiltrations of specific nerve branches. The aim of this study was to verify that US is an effective method for accurately locating the posterior tibial nerve and its terminal branches, such as the medial calcaneal branch, the first calcaneal branch, and the medial and lateral plantar nerves...

BACKGROUND: The causes of chronic discogenic back pain have not yet been clearly identified. Neural ingrowth around the annulus is widely considered to be one of the possible cause. However, neuropathy around the annulus has yet to be observed visually. We report a case of a hotspot that was observed in an epiduroscopic view, but not in imaging findings. CASE DESCRIPTION: A 46-year-old woman was admitted with pain in the back, left buttock, and posterior thigh for 2 years...

Background: Controlled diagnostic studies have established the prevalence of cervical facet joint pain to range from 36% to 67% based on the criterion standard of ≥ 80% pain relief. Treatment of cervical facet joint pain has been described with Level II evidence of effectiveness for therapeutic facet joint nerve blocks and radiofrequency neurotomy and with no significant evidence for intraarticular injections. However, there have not been any cost effectiveness or cost utility analysis studies performed in managing chronic neck pain with or without headaches with cervical facet joint interventions...

The tibial nerve is the larger terminal branch of the sciatic nerve and it terminates in the tarsal tunnel by giving lateral and medial plantar nerves. We present a rare case of trifurcation of the tibial nerve within the tarsal tunnel. The variant nerve curves laterally after branching from the tibial nerve and courses deep to quadratus plantae muscle. Interestingly, posterior tibial artery was also terminating by giving three branches. These branches were accompanying the terminal branches of the tibial nerve...

INTRODUCTION: Gluteal insufficiency is of concern with lateral approaches to total hip arthroplasty. Damage to the branches of the superior gluteal nerve may cause degeneration of the innervated muscles. The direct anterior approach exploits the intermuscular and internerval interval between tensor fasciae latae laterally and sartorius and rectus femoris muscle medially. In this study, the distance of the superior gluteal nerve in relation to anatomical landmarks was determined. MATERIALS AND METHODS: Two experienced surgeons implanted trial components in 15 alcohol glycerol fixed cadavers with 30 hips...

BACKGROUND: Lumbar facet arthropathy is a common cause of low back pain. Literature supports treatment with radiofrequency ablation (RFA) of associated nerves that innervate lumbar facets when alternative conservative therapies have failed. Diagnostic local anesthetic blocks precede therapeutic ablation, but have a false positive rate of 27-63%, and some have questioned their utility in predicting therapeutic response to RFA. The authors believe that injectate volume may be a contributing factor to false positivity...

High-resolution ultrasound (US) enables prompt depiction of muscles, tendons, ligaments, and peripheral nerves. It seems to be the best imaging modality for guiding perineural injections. The most complicated neurovascular network of the musculoskeletal system surrounds the cervical spine; so injection to that region is never an easy task. This article elaborates the regional anatomy and the use of US scanning and guidance for cervical interventions; for example, cervical root, superficial cervical plexus, stellate ganglion, cervical medial branch, greater occipital nerve, and third occipital nerve...

The orbicularis oculi muscle, an important mimetic muscle, was investigated to ascertain its anatomical relation to facial aging-especially its orbital part (Oo). Previous studies of the distinct muscle bundles frequently found inferior to the Oo have provided various definitions, including that of the malaris muscle. This study aimed to examine these muscle bundles and clarify their function in facial aging. Twelve heads of Japanese cadavers (average age: 82.5 years old) were dissected to observe the muscles, focusing in particular on those in the periorbital region...

BACKGROUND: The knowledge of sinonasal vasculature is inevitable in transnasal neurosurgery. We performed an anatomical study on the sphenopalatine artery from the perspective of skull base procedures. METHODOLOGY: To analyse the anatomical landmarks of the sphenopalatine artery, arterial skull corrosion casts (26 head halves) underwent endoscopic transnasal phantom surgery. Furthermore, we performed microsurgical dissection on formaldehyde-fixated cadavers with arterial perfusion (14 head halves) as well as studied Cone Beam CT-scans of anonymised patients and cadavers (115 head sides)...

BACKGROUND: The anterior iliac crest (AIC) is one of the most common sites for harvesting autologous bone, but the associated postoperative pain can result in significant morbidity. Recently, the transmuscular quadratus lumborum block (TQL) has been described to anesthetize the thoraco-lumbar nerves. This study utilizes a combination of cadaveric models and clinical case studies to evaluate the dermatomal coverage and analgesic utility of TQL for AIC bone graft donor site analgesia. METHODS: Ten ultrasound-guided TQL injections were performed in five cadaver specimens using a lateral-to-medial transmuscular approach...
