Logica riabilitativa nell'osteoporosi vertebrale
2003
L'importanza dell'esercizio terapeutico nel trattamento integrato dell'osteoporosi vertebrale deriva dal fatto che produce sul tessuto osseo effetti metabolici positivi. Scopo del rpogramma chinesiterapico è di ottenere un buon tonotrofismo dei musocli deficitari e rilassare quelli che per compenso sono in uno stato di contrattura permanente e quindi dolorosa. Il compito del fisiatra deve indirizzarsi verso l'istruzione e l'adattamento della vita personale e di relazione del soggetto osteoporotico.
Prevalence of Vertebral Fractures in Osteoporotic HIP Fractured Patients: The Focus Study

Surgical Highways to the Craniovertebral Junction: Is It Time for a Reappraisal?
2019
Background: The craniovertebral junction (CVJ) can be affected by a variety of congenital or acquired anomalies. Because of its complexity, a careful evaluation of bones and ligamentous structures in all three planes is required. This can be achieved by studying the CVJ in terms of several anatomical and radiological lines that have been visualized to facilitate understanding of its surgical anatomy. In this study we aimed to review the state-of-the art craniometric CVJ lines and approaches. Methods: In December 2016 a PubMed search was performed, including the search terms ‘CVJ surgical approach/line’, ‘cervical approach’, ‘craniometric measurement’, ‘CVJ anatomy’ and ‘ventral/dorsal/far-l…
Fractional Calculus as a New Perspective in the Viscoelastic Behaviour of the Intervertebral Disc
2022
The spinal column is the load-bearing structure of the human being along with its components, which together build a strong, resistant, and stable structure, but there are a few different pathologies from which it can suffer, such as herniated discs. The intervertebral disc acts as a shock absorber and ensures the spine’s great capacity to support high loads and different states of stress, thanks to its viscoelastic properties. Some studies have attempted to describe the viscoelastic behaviour of the intervertebral disc using classical rheological models, such as the Kelvin-Voigt, or multi-parameter models. Even if these models partially describe the viscoelastic response of disc, all visco…
The importance of level stratification for quantitative MR studies of lumbar intervertebral discs : a cross-sectional analysis in 101 healthy adults
2019
Purpose: To investigate whether quantitative T2-times depend on lumbar intervertebral disc (IVD) level. Methods: The lumbar spine (Th12/L1–L5/S1) of 101 participants (53.5% female, 30.0[± 3.6]years, 173.5[± 9.6]cm and 69.9[± 13.4]kg), without history of back pain, was examined on a 3T scanner with sagittal T2-mapping. All IVDs were stratified according to Pfirrmann grade and lumbar level, with mean T2-time determined for the entire IVD volume and in five subregions of interests. Results: Significant level-dependent T2-time differences were detected, both for the entire IVD volume and its subregions. For the entire IVD volume, Pfirrmann grade 2 IVDs displayed 9–18% higher T2-times in Th12/L1…
Upper thoracic-spine disc degeneration in patients with cervical pain.
2003
To study the relationship of upper thoracic spine degenerative disc contour changes on MR imaging in patients with neck pain. The relation between upper thoracic and cervical spine degenerative disc disease is not well established.One hundred and fifty-six patients referred with cervical pain were studied. There were 73 women and 77 men with a mean age of 48.6 +/- 14.6 years (range, 19 to 83 years). All MR studies were performed with a large 23-cm FOV covering at least from the body of T4 to the clivus. Discs were coded as normal, protrusion/bulge or extrusion.Degenerative thoracic disc contour changes were observed in 13.4% of patients with cervical pain. T2-3 was the most commonly affecte…
Autonomic Nerve Blocks
1988
Selective block of the sympathetic trunk was first reported by Sellheim and, shortly thereafter, by Lawen, Kappis, and Finsterer (1905–1910). In 1924, reports were published by Brumm and Mandl and by Swertlow. After 1930, the technique and the indications were established by White in the United States and Leriche and Fontaine in Europe.
Vertebral fragility fractures and balance disorders: postural evaluation

2020
"Difusión del anestésico local en el espacio paravertebral torácico tras bloqueo paravertebral guiado con ecografía: Estudio con Tomografía Computerizada Cone Beam" Nuria García Gregorio INTRODUCCIÓN El objetivo de este trabajo fue describir la difusión del anestésico local (AL) en el espacio paravertebral torácico (EPVT) tras bloqueo paravertebral (BPVT) guiado por ultrasonidos (US) mediante reconstrucción de imágenes de tomografía computerizada (TC) en 3D. El BPVT es ampliamente utilizado pero la difusión del AL y su extensión sensitiva es variable y poco predecible según los estudios. Dichos trabajos muestran resultados dispares, posiblemente por falta de homogeneidad en la técnica de bl…
Dynamics of Vertebral Column Observed by Stereovision and Recurrent Neural Network Model
2005
A new non-invasive method for investigation of movement of selected points on the vertebral column is presented. The registration of position of points marked on patient's body is performed by 4 infrared cameras. This experiment enables to reconstruct 3-dimensional trajectories of displacement of marked points. We introduce recurrent neural networks as formal nonlinear dynamical models of each point trajectory. These models are based only on experimental data and are set up of minimal number of parameters. Therefore they are suitable for pattern recognition problems.
