Xin Rong, Ziyang Liu, Beiyu Wang, Xuelin Pan, Hao Liu
BACKGROUND: Facet tropism is the angular asymmetry between the left and right facet joint orientation. Although debatable, facet tropism was suggested to be associated with disc degeneration, facet degeneration and degenerative spondylolisthesis in the lumbar spine. The purpose of this study was to explore the relationship between facet tropism and facet degeneration in the sub-axial cervical spine. METHODS: A total of 200 patients with cervical spondylosis were retrospectively analyzed...

BACKGROUND: X-linked hypophosphatemia (XLH) is the most common inherited form of renal phosphate wasting and inherited rickets. Patients have hyperplasia of fibrochondrocytes in tendons and ligaments, causing the structures to thicken and calcify. Thickening of the lamina, hypertrophy of facet joints, and calcification of spinal ligaments are sequelae of this condition and can result in central or foraminal stenosis that compresses nerve roots or the spinal cord. We present a case of XLH with calcification of the ligamentum flavum in which the patient was operated on using minimally invasive posterior decompression...

INTRODUCTION: Degenerative spondylolisthesis (DS) is usually seen at L4-L5 level and less frequently at L5-S1 level. This is a rare case report of spondylolisthesis of S1 over S2 with lumbarization of S1. Lumbarization of S1 is seen in just 1-2% of the population and to have spondylolisthesis in this segment is even rarer. The purpose is to report a rare case of DS at S1-S2 level. CASE REPORT: This is a single case report of a 66-year-old gentleman who presented with complains of lower backache for 2 years and acute retention of urine to the emergency department...

UNLABELLED: Lumbar spinal stenosis is one of most common pathologic conditions affecting the lumbar spine. Pain and/or disability in the low back and lower extremities with or without neurogenic claudication may occur as a result of compression of dural sac contents or nerve roots in the narrowed space. Bulging and protrusion, facet joint hypertrophy, and disc herniation combined with osteophytes and arthritic changes of facet joints can be the cause of lumbar spinal stenosis. Medical/interventional treatment may be considered as an initial treatment for patients with mild symptoms of lumbar spinal stenosis...

INTRODUCTION: Gluteal insufficiency is a common and challenging complaint. New concepts in pathobiomechanics and improved clinical understanding of chronic gluteal dysfunction have unmasked gluteus medius (GMed) tears as an underlying cause of enhanced trochanteric pain syndrome (GTPS). These tears are often missed or misdiagnosed as bursitis, but lead to prolonged chronic peritrochanteric pain. Clinic: The clinical signs are often dull pain on the lateral hip aspect, reduced hip abduction strength with positive Trendelenburg testing and a tendency for the leg to external rotation, as the internal rotation strength is reduced...

OBJECTIVE: Degenerative changes in posterior elements of the spine such as thickening or hypertrophy of the ligamentum flavum (LF) may result in spinal stenosis. In the present study, we aimed to investigate the potential factors including age, intervertebral disc degeneration (IDD), facet joint degeneration (FJD), end plate degeneration (EPD), which may affect LF thickening and to reveal the relationship among those factors at each level of lumbar spine by evaluating the magnetic resonance images (MRI)...

Overstimulation of the orthosympathetic system leads to cardiovascular cell and tissue damage through prolonged activation of β-1-2 adrenergic receptors (BARs). The more recent identification of the third isotype of BAR (B3AR) in cardiac myocytes and endothelial cells with a distinctive coupling and effect on cardiac function and remodelling introduced a new facet to this paradigm. In particular, B3AR is up-regulated in cardiac disease and less prone to homologous desensitization, which may reinforce its influence on the diseased myocardium...

Ankle impingement syndromes are common disorders that can be attributed to many factors. To the best of our knowledge, posteromedial ankle impingement syndromes caused by talocalcaneal coalition have never been previously reported. The present report describes 5 patients with posteromedial ankle pain and inversion limitation. The physical examination, radiographic, and magnetic resonance imaging findings suggested posteromedial ankle impingement syndrome and talocalcaneal coalition. The 5 patients underwent surgery after conservative treatment had failed...

BACKGROUND: Congenital anomalies are commonly encountered in the craniovertebral junction because of its unique embryologic development. The craniovertebral junction usually comprises the occiput, atlas, and axis. However, malrotation of the atlas (C1) in between the occiput (C0) and axis (C2) with Chiari I malformation as well as unilateral hypertrophy of the atlanto-occipital joint and a lateral mass manifesting features of high cervical myelopathy is a rarely reported anomaly. CASE DESCRIPTION: A 22-year-old woman presented to us with high cervical compressive myelopathy...

STUDY DESIGN: A study of lumbar ligamentum flavum (LF). OBJECTIVE: The aim of this study was to identify LF hypertrophy related microRNAs (miRNAs) expression profile and to investigate the role of miRNAs in the development of LF hypertrophy in lumbar spinal stenosis (LSS). SUMMARY OF BACKGROUND DATA: Although histologic and biologic literature on LF hypertrophy is available, the pathomechanism is still unknown. Accumulating evidence suggests that microRNAs (miRNAs) participate in many physiologic processes, including cell proliferation, differentiation, and fibrosis, but the role of specific miRNAs involved in LF hypertrophy remains elusive...

Herein we discuss a case of a 55 year old male presenting with history suggestive of sciatica on the left leg. Straight leg raising (SLR) test was positive at 45 degrees on the left side. His ankle reflex was absent and the power of extensor hallusus longus (EHL) was 4/5 on the same side. MRI lumbosacral spine revealed left paramedian disc prolapsed on L4/L5 level with spinal canal diameter of 9mm.However since his bilateral extensor digitorm brevis (EDB) were wasted, we suspected associated lumbar canal stenosis and thereby opted for laminectomy and discectomy in this case...
