The ongoing chronic inflammation and subsequent fibrosis play an important role in ligamentum flavum(LF) fibrosis and hypertrophy in patients with lumbar spinal canal stenosis (LSCS). Leptin is a chronic inflammatory mediator and involved in the fibrotic process in multiple organ systems. The present study aimed to investigate the role of leptin in LFfibrosis and its related regulatory mechanisms. The LF specimens were obtained during the surgery from 12 patients with LSCS(LSCS group) and 12 control patients with lumbar disc herniation (LDH group)...

PURPOSE: A low cost, reproducible radiographic method of diagnosing congenital lumbar spinal stenosis (CLSS) is lacking. We hypothesized that the Cobb angle for lumbar lordosis would be smaller in patients with CLSS, based on observations in our spine clinic patient population. Here, we compared lumbar lordosis Cobb angles with the radiographic ratio method in patients with normal spine imaging, degenerative spinal stenosis, and with CLSS. MATERIALS AND METHODS: Orthopedic surgeons categorized patients with low back pain as "Normal," "Degenerative spinal stenosis," and "CLSS" based on clinical presentation and findings on lumbar magnetic resonance imaging...

Along with the population aging in China, patients with lumbar spinal stenosis(LSS) caused by recessive change incessantly increase. At present, there is no adequate evidence to recommend any specific nonoperative treatment for LSS, and surgery is still an effective method. The cilincal symptoms of the patients without conservative treatment got improvement after surgery, which is the strongest evidence base. Spinal instability after simple decompression promotes the development of fusion technique, and the accelerated adjacent segment degeneration and no relief in symptoms after fusion lead to dynamic fixation technology emerge as the times require...

METHODS: The clinical data of 86 patients with single segmental lumbar vertebra diseases treated from June 2011 to June 2013 was retrospectively analyzed. There were 33 males and 53 females, aged from 28 to 76 years old with an average of 53.0 years. Among them, there were 39 cases of lumbar disc degeneration, 22 cases of lumbar disc herniation complicated with spinal canal stenosis, 9 cases of huge lumbar disc herniation and 16 cases of lumbar degenerative spondylolisthesis (Meyerding degree I )...

Spinal Epidural lipomatosis (SEL) is an uncommon condition, usually presents in young and middle aged patients, with male preponderance. Idiopathic SEL is rare, particularly in 8th decade of life. SEL should also be considered as a differential diagnosis in approach of elderly patient presenting with lumbar canal stenosis. Such a case of 77 year old man is presented here.

Patients with low back pain (LBP) frequently undergo various imaging studies in the pursuit of a more precise diagnosis. Ultrasound (US) has the advantage of being a widely available, multiplanar, fast and radiation-free diagnostic tool. Moreover, compared to most of the other imaging modalities, it is particularly efficient in the visualization and assessment of soft tissues. Consequently, the question about the possible diagnostic application of US in such a common pathology as LBP is very relevant to the clinical practice...

The aim of the present study was to examine the curative effect of dynamic fixation Coflex treatment for patients with degenerative lumbar spinal stenosis. In the present study, 78 patients with degenerative lumbar spinal stenosis were recruited and divided equally into the control and observation groups. The control group was treated with traditional decompression fusion and the observation group received dynamic fixation Coflex system. Surgery and hospitalization were shorter in the observation group than in the control group...

BACKGROUND: Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a potentially disabling disorder. Little is known about the contributors to severe forms of the illness. We describe three consecutive patients with severe ME/CFS whose symptoms improved after recognition and surgical management of their cervical spinal stenosis. METHODS: All patients satisfied clinical criteria for ME/CFS and orthostatic intolerance, and were later found to have cervical spinal stenosis...

BACKGROUND: Pseudomeningoceles most commonly occur due to prior trauma or surgery and are often located in the posterior paraspinous tissues. Here, we report a case of an intraosseous pseudomeningocele that mimicked an intra-osseous T2 hyperintense lesion in the L1 vertebral body. CASE DESCRIPTION: A 64-year-old male presented with back, left lateral thigh and left knee pain lasting several months. He had no prior history of trauma or surgery. Radiographs of the lumbar spine showed mild levoscoliotic curvature of the lumbar spine, Baastrup's changes between the spinous processes, multilevel degenerative disc disease and facet arthropathy...

BACKGROUND: Thoracic spinal stenosis is a common vertebral degenerative disease, and treatment remains challenging. In recent years, transforaminal endoscopic decompression has been widely used for treating lumbar degenerative diseases. However, the efficacy of this procedure for thoracic spinal stenosis has yet to be established. Herein, we report a case of thoracic spinal stenosis treated with transforaminal endoscopic decompression under local anesthesia. CASE REPORT: An 88-year-old man presented with a 1-month history of progressive paralysis and dysesthesia in the bilateral lower extremities...

OBJECTIVE: To discuss the causes of unsatisfied cervical posterior decompression surgery and describe the overhauling strategies and precaution. METHODS: The clinical data of 14 patients required revision surgery were retrospectively analyzed, and these patients with unsatisfied effects were due to cervical posterior decompression surgery from January 2012 to December 2014. Overhauling reasons were analyzed and then different revision procedures were performed. The functions of cervical cord and ambulation were evaluated respectively by modified Japanese Orthopedic Association(mJOA) score and Nurick grade according to the course order:preoperative for the first time, pre-revision and at final follow-up...

BACKGROUND AND STUDY AIMS:  The diagnosis of a lumbar spinal stenosis demands advanced diagnostic radiologic techniques. In recent decades magnetic resonance imaging (MRI) has replaced myelography, now considered an old-fashioned technique. It was our hypothesis that functional myelography still plays an important role in selected cases. We investigated how our surgical strategy was influenced by the results of MRI, functional myelography, and postmyelography computed tomography (CT) in patients with a lumbar spinal stenosis...
