Book excerpt: ABSTRACT: Motion is an important function of the human spine and accurate measurement of that motion is critical to assessing spinal health and the effect of treatments. There is a great need for tools that allow accurate 3D intervertebral spine motion to be measured in vivo. The purpose of this study is to develop a method for registering a 2D radiograph with a 3D CT scan for the purpose of measuring 3D motion in the spine. This goal was achieved in three phases. The first phase of this project evaluated the accuracy of a fluoroscopic object recognition technique to measure the 3D position and orientation of a cervical disc arthroplasty implant. Although the experimental uncertainties of the proposed technique have been extensively analyzed with respect to the measurement of knee implant motions, the size, geometry, and type of motion of spine implants requires that these uncertainties be determined specifically for spine components. These uncertainties were determined using a cadaver model. The second phase of this project developed and evaluated the static accuracy and capture range of a novel 2D/3D image registration methodology using existing gold standard data. Digitally reconstructed radiographs were used in the registration algorithm to take advantage of the internal contours and density variation of the bony anatomy. In the third phase of this project, the uncertainties of measuring dynamic 3D kinematics of cervical vertebrae were determined. The tools developed in this project will allow clinicians and researchers to accurately quantify the performance of the normal spine as well as new implants designed to restore motion to the spine. This methodology also has applications for other joints, such as the shoulder, ankle, knee and hip.

Available in PDF, EPUB and Kindle. Book excerpt: Unique resource from internationally renowned experts details the key role of sagittal spine balance Through evolution, human verticality became associated with a wide range of normal pelvic shapes and associated pelvic incidence angles (PIs). While all types of sagittal alignment generally provide adequate support to young adults, age, stress, and related degeneration can progressively lead to sagittal imbalance and contribute to various spinal pathologies. Sagittal Balance of the Spine by Pierre Roussouly, João Luiz Pinheiro-Franco, Hubert Labelle, Martin Gehrchen, and a cadre of esteemed international contributors focuses on the importance of sagittal alignment and spino-pelvic shape identification in clinical practice. Offering the most comprehensive text on sagittal balance to date, this state-of-the-art, richly illustrated book fills a void in the literature, offering clinical pearls throughout seven sections and 24 chapters. Key Highlights The biomechanics of sagittal balance including spine modeling, primary parameters, spinal curves segmentation, and lumbar lordosis classification The role of sagittal balance in low back pain and degeneration, with discussion of spinal orientation and the contact forces theory, spinal degeneration associated with spinopelvic morphotypes, and compensatory mechanisms Comprehensive analysis of the relationship between sagittal imbalance and isthmic lysis spondylolisthesis, degenerative spondylolisthesis, Scheuermann's kyphosis, adolescent idiopathic scoliosis, and adult scoliosis Posterior and anterior treatment approaches – from spinal fixation and spinal fusion – to spinal osteotomy techniques and management of surgical failure This text is essential reading for every neurosurgical and orthopaedic resident, as well as veteran surgeons who evaluate and treat patients with spine conditions. Clinicians will learn why incorporating sagittal balance evaluations into spinal exams is integral to devising more effective treatment strategies and achieving improved outcomes.

Download or read book Development and Validation of Novel Methods to Track Three Dimensional Spine Kinematics During Dynamic Trunk Movements Using a Time of Flight RGB D Camera written by Wantuir Carlos Ramos Junior and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Low back pain (LBP) is a common and costly musculoskeletal disorder. Clinicians and researchers frequently assess dysfunction in LBP by observing patient's movement quality during pre-determined tasks using technically challenging and expensive motion capture devices. However, the cost and expertise needed to use these devices are direct barriers to their widespread adoption in clinical settings where direct benefits could be realized by LBP patients. RGB-D cameras are a potential inexpensive and less time-intensive motion capture alternative, which have been validated for analyses of gait, postural control, ergonomics, and human anatomy. However, as manufactured, RGB-D cameras are not ready for specific kinematic analyses, such as lumbar spine motion, as the native artificial intelligence (AI) models do not adequately detect the number and location of trunk joints to accurately track three-dimensional kinematics. In this thesis a proof of concept framework to adapt RGB-D cameras to accurately measure lumbar spine kinematics is presented, which is separated into two research studies: 1) validation of an RGB-D depth-based algorithm against an optoelectronic motion capture system of reference for measuring spine motion, and 2) the development of a markerless method of measuring lumbar spine kinematics. In study one, 12 healthy young adults (6M, 6F) performed 35 cycles of repetitive flexion-extension with infrared reflective marker clusters placed over their T10-T12 spinous processes and sacrum, while motion capture data were recorded simultaneously by one RGB-D camera and a 10-camera optoelectronic motion capture system. Lumbar spine joint angle range of motion (ROM) were extracted and compared between systems. Root mean squared error (RMSE) values were very low across all movement axes (RMSE ≤ 2.05° ± 0.97°), and intraclass correlations (ICCs) were considered excellent across all axes (ICC2,1 ≥ 0.849), while Bland-Altman plots revealed that, on average, the RGB-D camera slightly underestimated flexion-extension angles (≈ -1.88o) and slightly overestimated lateral bending and axial twisting angles (≈ 0.58o). In study two, a single RGB-D camera was used to capture infrared, depth, and colour image data of 15 participants performing two batteries of 10 cycles of repetitive trunk flexion-extension under two conditions: marked (i.e. hand drawn markers on key anatomical locations on the back) and unmarked. The collected data were used to create a custom four module convolutional neural network (CNN; SpineNet) to segment the human back into upper back, lower back, and spine regions and to subsequently extract lumbar spine kinematics. SpineNet was trained and tested on ten marked participants in a train:test ratio of 80:20. Images of five additional participants without markers were used to evaluate SpineNet's generalizability. Quantitative image segmentation analysis on marked data had good similarity and accuracy between their prediction and ground truth across all individual modules (mPAFG ≥ 0.8855; mJBKG ≥ 0.8391; mJFG ≥ 0.7884; fwJBKG ≥ 0.9672; fwJFG ≥ 0.8087) when the background class was ignored. Qualitative image segmentation analysis on unmarked data showed that Colourized and Surface Normal modules presented a more uniform and robust class morphology throughout frames than infrared (IR) and Fusion modules. All modules extracted kinematics similarly and were compared with their ground truth labels, showing low error levels across all movement axes (RMSE ≤ 3.66o), and good agreement on the flexion-extension and axial twist axes (ICC2,1 > 0.907; CI 95% [0.640, 0.990]); however kinematic extraction in the lateral bend axis was poor (-0.212

Download or read book Developing D flow Applications for Measuring Parameters and Visualising Geometry of Spine of Patients with Scoliosis written by Edwin Andione Khundi and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The knowledge of geometry of spine is quite useful in treatment of various diseases of the spine such as scoliosis. Clinicians usually obtain geometry of spine or vertebrae column using radiology although other imaging techniques such as computed tomography, ultrasound, nuclear imaging and magnetic resonance imaging (MRI) are also used. The main limitation of radiography is that it is two dimensional while spine geometry of scoliosis is three dimensional. Thus the main aim of this project was to develop a D-flow based application that will calculate and visualise three dimensional shape of the spine using motion capture system. Three applications namely; pointing wand calibration, marker dependent and marker independent applications, were developed in D-flow software during the project. The applications were then tested by visualising geometry of skeleton and S- shaped cable. The marker dependent application was tested by attaching passive Infrared markers to the skeleton while for the marker independent no marker was attached to the skeleton. For the marker dependent application, the markers attached on skeleton were labelled in a particular sequence by pointing the wand close to a marker and pressing button of phidget. After labelling all markers the software visualised the spine automatically. For the marker independent application the geometry of the spine was obtained by pointing the wand at each anatomical land mark of vertebrae and pressing button of phidget to capture coordinates of that position. The protocol of labelling vertebrae for marker independent starts from cervical region up to sacral region. The coordinates of the labelled points were used to calculate different parameters and reconstruct a visualisation of the spine. The numerical results of parameters such as angle parameters from both applications and also from manual measurements were analysed and compared using statistical software Minitab. Consequently there was no much difference between values of parameters from both developed visualising applications. Hence both could accurately visualise the geometry of spine and calculate parameters defining curvature of the spine. In conclusion the developed applications were easy to use and besides they could accurately measure the parameters and visualise innovatively the shape of the spine as required.
