We describe a method to automatically detect and label the vertebrae in human lumbar spine MRI scans. Our contribution is to show that marrying two strong algorithms (the Deformable Part Model (DPM) object detector of Felzenszwalb et al. [9], and inference using dynamic programming on chains) together with appropriate modelling, results in a simple, computationally cheap procedure, that achieve...

This paper presents a method based on articulated models for the registration of spine data extracted from multimodal medical images of patients with scoliosis. With the ultimate aim being the development of a complete geometrical model of the torso of a scoliotic patient, this work presents a method for the registration of vertebral column data using 3D magnetic resonance images (MRI) acquired...

This paper proposes an automatic method for vertebra localization, labeling, and segmentation in multi-slice Magnetic Resonance (MR) images. Prior work in this area on MR images mostly requires user interaction while our method is fully automatic. Cubic intensity-based features are extracted from image voxels. A deep learning approach is used for simultaneous localization and identification of ...

INTRODUCTION: In many elderly people, one or more vertebrae lose height, especially anteriorly. Such anterior “wedge” deformities lead to senile kyphosis a condition that can cause pain, disability and loss of self-esteem. Metabolic processes weaken elderly bone, and altered load-sharing in the elderly spine causes mechanical damage to be concentrated in the anterior vertebral body (1). The res...

OBJECTIVE To determine the entry for the dorsal pedicular screw in relation to the notch present at the junction of base of the lateral margin of superior articular process with superior border of transverse process in dorsal spine. The advantage of this technique is a constant and easily identifiable entry point which does not involve partial resection of the inferior facet, thus maintaining s...

Clinically, a cachectic and stunted boy, weight and height SD scores were -5,05 and -3,65 respectively. He had fever, anaemia, splenomegaly and polyartrhitis. There was complete immobility and severe pain of his lumbar spine. Xrays revealed compression fractures of all lumbar vertebrae. Bone mass densitometry confirmed severe osteoporosis (Z-score -4.5 SD). ESR: 33, Hb: 7.4 g/dl, CRP 112 mg/dl.

A 59-year-old man presented with a one-year History of progressive dysphagia to the point that he could no longer swallow solid foods. Cervical spine X-Ray Elms demonstrated massive anterior new bone formation along the anterior surface of C3 to C7 vertebrae. Evaluation with barium swallow and cervical computed tomograhpy demonstrated oesophageal compression. Resection of the anterior onteophyt...

A revised appreciation of the evolution and the nature of bone in general and of vertebrae in particular, allows revisiting the human spine to usher in some new principles and more rational parlance, that embody spine's phylogeny, ontogeny, anatomy and physiology. Such an approach accords primacy to spine's soft-tissues, and relegates to its bones a secondary place.

A detailed lumbar spine FE component model (including vertebrae, inter-vertebral discs, all ligaments and facet joints of T12-L5) was built per the Global Human Body Model Consortium (GHBMC) CAD data. The lumbar model was correlated with the Post-Mortem Human Subject (PMHS) lumbar spine tests under flexion, compression and anterior shear loading modes in the physiological ranges (Belwadi, 2008)...

STUDY DESIGN A cross-sectional comparative study between chronic low back pain (CLBP) patients and healthy control subjects. OBJECTIVE The aim of this study was to investigate reorganization in the sensory cortex by comparing cortical activity due to mechanosensory stimulation of the lumbar spine in CLBP patients versus a control group by using functional magnetic resonance imaging (fMRI). ...
