The aim of the study is to identify possible differences in the prevalence of biological stress markers (cribra orbitalia, linear enammel hypoplasia), dental caries, activity markers (Schmorl's nodes) and markers of violence (traumatic lesions) in populations from a typical graveyard around the first church (9(th)-10(th) century AD) in the stronghold and from settlement burials in the southern bailey (second half of the 9(th) - beginning of the 10(th) century AD) of Slavs from Pohansko (Czech Republic). Cribra orbitalia and enamel hypoplasia did not markedly differ in either population...

BACKGROUND: Degenerative lumbar spinal stenosis (DLSS) is a common health problem in the elderly and usually associated with three-joint complex degeneration. Schmorl's nodes (SNs) are described as vertical herniation of the disc into the vertebral body through a weakened part of the end plate that can lead to disc degeneration. Since SNs can harm the spine unit stability, the association between DLSS and SNs is expected. The aim of this study is to shed light on the relationship between degenerative lumbar spinal stenosis and SNs...

BACKGROUND: WNT signaling plays a major role in bone and cartilage metabolism. Impaired WNT/β-catenin signaling leads to early-onset osteoporosis, but specific features in bone and other tissues remain inadequately characterized. We have identified two large Finnish families with early-onset osteoporosis due to a heterozygous WNT1 mutation c.652T>G, p.C218G. This study evaluated the impact of impaired WNT/β-catenin signaling on spinal structures. METHODS: Altogether 18 WNT1 mutation-positive (age range 11-76years, median 49years) and 14 mutation-negative subjects (10-77years, median 43years) underwent magnetic resonance imaging (MRI) of the spine...

PURPOSE: Evidence-based facts regarding spine abnormalities and back pain are needed in order to develop rehabilitation programs and prevent spine injuries in young skiers. The aim therefore is to identify MRI changes in the thoraco-lumbar spine and the lifetime prevalence of back pain, as well as the association between them, in young skiers compared to non-athletes. METHODS: Seventy-five young elite alpine and mogul skiers, age range 16-20 years, were compared with 27 non-athletic controls...

The authors of the present work evaluate the trauma observed on the skeletal remains of an individual from medieval Gloucester and reconstruct the events that led to his death. The almost complete skeleton was recovered from the cemetery of St Owen and dates to the late medieval period. Several methods were used to determine the sex and age of the individual. The anthropological examination showed that the remains belonged to a young male, between the ages of 17 and 19 years. The young man also had antemortem pathologies that were related to his diet and lifestyle, as he appears to have had iron-deficiency anemia and Schmorl nodes...

Minimally invasive percutaneous imaging-guided techniques have been shown to be safe and effective for the treatment of benign tumors of the spine. Techniques available include a variety of tumor ablation technologies, including radiofrequency ablation, cryoablation, microwave ablation, alcohol ablation, and laser photocoagulation. Vertebral augmentation may be performed after ablation as part of the same procedure for fracture stabilization or prevention. Typically, the treatment goal in benign spine lesions is definitive cure...

BACKGROUND CONTEXT: Bony vertebral end plates must be porous to allow metabolite transport into the disc, and yet strong to resist high intradiscal pressure (IDP). End plate defects may therefore have nutritional and mechanical consequences for the disc, depending on their size and type. We hypothesize that broad, diffuse defects are more closely associated with disc decompression and degeneration than are focal Schmorl's node-type defects. PURPOSE: This study aimed to determine how the size and type of end plate defects are related to decompression and degeneration in the adjacent intervertebral disc...

BACKGROUND: Lumbar disc disease has a disabling impact on global people with heavy burden on society, mainly consisting of lumbar disc degeneration (LDD) and lumbar disc herniation (LDH). The recently released lumbar disc nomenclature version 2.0 deepens our understandings on the diseases. Consequently, there is an urgent need to clarify the occurrence and distribution features of LDD and LDH in a large-scale sample in terms of the novel version. QUESTION/PURPOSES: We asked: (1) Is there a difference in the occurrence and distribution hallmarks of LDD and LDH in a population-based large-scale sample? (2) Does the novel nomenclature version bring novel vision on lumbar disc disease? METHODS: Five thousand two hundred eighty-eight consecutive cases (26,440 lumbar discs) undergoing lumbar spine MRI were retrospectively included from Jan 2008 to Dec 2010 in a territory university hospital...

BACKGROUND: Differentiation of vertebral metastases from Schmorl's nodes, especially with fluorine-18-fluorodeoxyglucose ((18)F-FDG) uptake, is very important for the appropriate management of these patients in case they have malignancy. We aimed to evaluate the value of (18)F-FDG positron emission tomography/computed tomography (PET/CT) in differentiating vertebral metastases from Schmorl's nodes with (18)F-FDG uptake. SUBJECTS AND METHODS: Fourteen patients with malignancy underwent (18)F-FDG PET/CT, which showed abnormal (18)F-FDG uptake in 19 Schmorl's nodes...

PURPOSE: To determine whether fat-signal-fraction (FF) map using a modified Dixon sequence could help differentiate benign from malignant bone lesions. MATERIALS AND METHODS: Spine magnetic resonance images (MRIs) of 120 consecutive patients were studied by using a 3T MRI with standard T1 -weighted image (T1 WI) and modified-Dixon sequence for FF measurement. There were three groups: a control group (n = 51) with normal vertebrae; a benign group (n = 40) with focal red marrow deposition, Schmorl's nodes, benign compression fracture, or Modic type 1 endplate degeneration; a malignant group (n = 29) with spinal malignancies...

A 10-year-old girl with a 2-week history of atraumatic back pain presented to the emergency department with difficulty ambulating and a history of 2 episodes of urinary incontinence in the past week. Her examination was significant for pain with movement, tenderness to palpation in the lower thoracic spine, and no neurological deficits. In this case, the child was found to have a Schmorl node at T8 in the superior aspect of the vertebral body. Schmorl nodes are protrusions of the cartilage of the intervertebral disc through the vertebral body endplate and into the adjacent that is more commonly reported in the adult population...

INTRODUCTION: Schmorl's Nodes (SN), which appear as defects in superior and inferior endplates of vertebrae, are commonly seen around the thoracolumbar junction. They may be asymptomatic or symptomatic. Their prevalence varies with respect to age, gender, regions involved and other associated disc or vertebral findings. AIM: SN is quite a common finding on the Magnetic Resonance Imaging (MRI) of the spine. The purpose of the study was to evaluate the prevalence of SN in the patients who underwent MRI whole spine in the radiology department, ascertain its clinical relevance and to compare the prevalence of SN in the study population with the prevalence in rest of the Indian and global population described already in the literature...

Beyond the familiar disk herniations with typical clinical features, intervertebral disk pathologic conditions can have a wide spectrum of imaging and clinical manifestations. The goal of this review is to illustrate and discuss unusual manifestations of intervertebral disk pathologic conditions that radiologists may encounter, including disk herniations in unusual locations, those with atypical imaging features, and those with uncommon pathophysiologic findings. Examples of atypical disk herniations presented include dorsal epidural, intradural, symptomatic thoracic (including giant calcified), extreme lateral (retroperitoneal), fluorine 18 fluorodeoxyglucose-avid, acute intravertebral (Schmorl node), and massive lumbar disk herniations...
