The polypeptide hormone calcitonin is well known clinically for its ability to relieve osteoporotic back pain and neuropathic pain such as spinal canal stenosis, diabetic neuropathy, chemotherapy-induced neuropathy, and complex regional pain syndrome. Because the analgesic effects of calcitonin have a broad range, the underlying mechanisms of pain relief by calcitonin are largely unknown. However, recent studies using several types of chronic pain models combined with various methods have been gradually clarifying the mechanism...

Compressive cervical myelopathy secondary to degenerative changes in the cervical spine is a common cause of neurologic morbidity in the elderly. Identification of canal stenosis and addressing it surgically in addition to the obvious compressive lesions is essential to obtain satisfactory results. We attempt to define the saggital and transverse diameters in a normal adult population presenting at our centre with head injuries. We found that the values were lower than those reported in comparable studies for a western population, and also that the dimensions in women are significantly lower than in men...

Human lumbar spine usually consists of five vertebrae; however, some individuals have vertebral anomalies with four or six lumbar vertebrae because of sacralized fifth lumbar vertebra (L5 sacralization) or lumbarized first sacral vertebra (S1 lumbarization), respectively. These vertebral anomalies are called lumbosacral transitional vertebra (LSTV). Although LSTV is an asymptomatic anomaly, it is known to cause misconception in spinal counts and in spinal level at lumbar spinal surgery. The purpose of this study is to evaluate how LSTV affects the diagnosis and surgeries in lumbar spine disorders...

Thoracic disc herniation is a rare pathology for which surgical treatment is difficult. The discovery of asymptomatic or only slightly symptomatic lesions can be problematic, especially in cases of marked canal stenosis. The possibility of spontaneous resorption has been documented by a few case reports but there is no study on this subject. Our objective was to compare the clinical and radiological data for two groups of patients with significant thoracic herniation (occupying more than 20% of the spinal canal): one showing spontaneous resorption (group 1) and the other persistence of the lesion during follow up (group 2)...

Diffusion imaging is a promising technique as it can provide microstructural tissue information and thus potentially show viable changes in spinal cord. However, the traditional single-shot imaging method is limited as a result of various image artifacts. In order to improve measurement accuracy, we used a newly developed, multi-shot, high-resolution, diffusion tensor imaging (DTI) method to investigate diffusion metric changes and compare them with T2 -weighted (T2W) images before and after decompressive surgery for cervical spondylotic myelopathy (CSM)...

PURPOSE: Weight bearing does alter the dimension of lumbar spinal canal, but no study has analyzed its clinical correlation. This study aims to evaluate whether the changes in dural sac cross-sectional area (DSCA) and sagittal anteroposterior (AP) diameter on standing magnetic resonance imaging (MRI) correlate better with clinical symptoms of lumbar spinal stenosis. METHODS: Seventy consecutive patients with neurogenic claudication were prospectively recruited to undergo a 0...

The molecular mechanism underlying the fibrosis of ligamentum flavum(LF) in patients with lumbar spinal canal stenosis(LSCS) remains unknown. MicroRNAs are reported to play important roles in regulating fibrosis in different organs. The present study aimed to identify fibrosis related miR-21 expression profile and investigate the pathological process of miR-21 in the fibrosis of LF hypertrophy and associated regulatory mechanisms. 15 patients with LSCS underwent surgical treatment were enrolled in this study...

INTRODUCTION: A large proportion of adults suffer from neck pain at some points of their life and show altered ranges of spinal canal morphometry in various studies. The differences in values are also seen due to genetic, hormonal and other factors too. Torg's ratio is a widely accepted measurement to eliminate such discrepancies. The measurement of Space Available for Cord (SAC) is also gaining importance as spinal stenosis is a contributor to neck pain. AIM: (1) To examine the cervical spinal canal and spinal cord morphometric determinants in symptomatic sub-Himalayan North Bengal population and to compare the obtained data with other populations; (2) To determine whether Torg's ratio vary with gender or not; (3) To determine SAC values in symptomatic individuals...

INTRODUCTION: The laminoplasty has been the most widely used surgical method for OPLL. In recent years, increasing attention has been drawn to the anterior operative approaches for surgical treatment of cervical OPLL. However, which method is the optimum selection for therapy of cervical OPLL is still obscure. Therefore, we performed this prospective nonrandomized clinical studyin patients with multilevelcervical myelopathydue to OPLL and compare thetherapeutic efficiencyof laminoplastyand anterior approach (cervical discectomy and/or cervicalcorpectomy) in the management of multi-level cervical OPLL...

OBJECTIVE The flexed posture of the proximal (L1-3) or distal (L4-S1) lumbar spine increases the diameter of the spinal canal and neuroforamina and can relieve symptoms of neurogenic claudication. Distal lumbar flexion can result in pelvic retroversion; therefore, in cases of flexible sagittal imbalance, pelvic retroversion may be compensatory for lumbar stenosis and not solely compensatory for the sagittal imbalance as previously thought. The authors investigate underlying causes for pelvic retroversion in patients with flexible sagittal imbalance...
