AB1197 Changes in Lumbar Spinopelvic Pattern of Movement Influence the Flexion Relaxation of the Erector Spinae
2015
Background In healthy subjects, the erector spinae muscles (ES) exhibits a relaxation of its electrical activity when the trunk is nearby its full flexion. Objectives To find out the influence of exhibiting a lumbar spine or a pelvis dominant pattern of movement during trunk flexion from upright position on the appearance of the myoelectric relaxation of the erector spinae.

Identifizierung unbekannter Leichen durch Röntgenbildvergleich
1995
Between 1987 and 1993, 30 unknown bodies were identified by means of pre- and postmortem radiographs at the Forensic Institute in Mainz. Our experience indicates that radiological identification comprises a useful, rapid and cheap method, at least as valuable as dactyloscopy or odontological comparisons. The ages of available radiographs were up to 25 years; the most suitable regions are the skull (11), pelvis and lumbar spine (6), lower femur and knee (5) and distal leg with the ankle joint (5). In respect of the problem of objectifying the probability of identity, possibilities for solutions are shown.
Die Sonographie der Lendenwirbelsäule und des lumbosakralen Überganges - Sonoanatomie und Möglichkeiten der sonographisch gesteuerten Facettengelenks…
2008
QUESTION Is sonography helpful in facet joint infiltration of the lumbar spine? METHOD The sonoanatomy of the lumbar spine and the of lumbosacral junction was examined and described in a skeleton and in 10 volunteers. One representative cross section and 3 longitudinal sections were defined. According to these results (no neurological symptoms) the possibilities of ultrasound guided infiltration of the facet joints was examined in 78 patients (36 female, 42 male, average age 55 y., 38-78 y.) with chronic low back pain and increase of pain by hyperextension. 5 ml Carbostesin partially in combination with steroids were applied to each joint. In all cases the tip of the syringe could be placed…
A new tool to improve pedicle screw placement accuracy in navigated spine surgery: A monocentric study
2021
Objective Navigated instrumented spine surgery is burden by a low but significant screw mispositioning risks, respectively, for the 2D imaging system from 15 to 40% and, for the 3D imaging system, ranging from 4.1 to 11.5%. The primary objective of this study was to demonstrate the efficacy of a new "screw-like" tool in order to further decrease pedicle screws mispositioning rate during vertebral navigated spine surgery. Materials and methods Between January and June 2019 an initial case series of 18 patients were enrolled. All patients underwent a pedicle screw fixation, both in thoracic (Th10-Th12) and lumbosacral (L1-S1) spine, using O-arm (Medtronic Navigation, Louisville, Colorado) and…
Changes in spinal range of motion after a flexibility training program in elderly women

Although several studies have shown positive outcomes in response to spinal flexibility training programs, little is known about the management of sets and repetitions in traini…
Long Term Leisure Time Physical Activity Has a Positive Effect on Bone Mass Gain in Girls
2009
The purpose of this 7-year prospective longitudinal study was to examine whether the level and consistency of leisure-time physical activity (LTPA) during adolescence affected the bone mineral content (BMC) and bone mineral density (BMD) attained at early adulthood. The study subjects were 202 Finnish girls who were 10 to 13 years of age at baseline. Bone area (BA), BMC, and BMD of the total body (TB), total femur (TF), and lumbar spine (L2–L4) were assessed by dual-energy X-ray absorptiometry (DXA). Scores of LTPA were obtained by questionnaire. Girls were divided into four groups: consistently low physical activity (GLL), consistently high (GHH), and changed from low to high (GLH) and fro…
Thoracic dumbbell spinal chordoma mimicking a schwannoma
2021
Background: Epidural dumbbell-shaped chordomas are localized slow growing, and malignant/aggressive neoplasms. Here, we present a 62-year-old male with a T3-T4 dumbbell-shaped chordoma and reviewed the appropriate literature. Case Description: A 62-year-old male presented with a three-month history of thoracic pain. When the thoracolumbar magnetic resonance (MR) showed a T3-T4 dumbbell-shaped intracanalicular/extradural tumor, he underwent tumor removal. After the histological examination proved the lesion was a spinal chordoma, he underwent a secondary radical transthoracic tumor resection. Postoperatively, the patient was able to walk without assistance, and at 6-month follow-up, was neu…
Operator-Related Errors and Pitfalls in Dual Energy X-Ray Absorptiometry: How to Recognize and Avoid Them.
2020
Dual-energy X-ray absorptiometry (DXA) is the most common modality for quantitative measurements of bone mineral density. Nevertheless, errors related to this exam are still very common, and may significantly impact on the final diagnosis and therapy. Operator-related errors may occur during each DXA step and can be related to wrong patient positioning, error in the acquisition process or in the scan analysis. The aim of this review is to provide a practical guide on how to recognize such errors in spine and hip DXA scan and how to avoid them, also presenting some of the most common artifacts encountered in clinical practice.
Mechanical loading influences the lumbar intervertebral disc : A cross‐sectional study in 308 athletes and 71 controls
2021
There is evidence in animal populations that loading and exercise can positively impact the intervertebral disc (IVD). However, there is a paucity of information in humans. We examined the lumbar IVDs in 308 young athletes across six sporting groups (baseball, swimming, basketball, kendo, soccer and running; mean age 19yrs) and 71 non‐athletic controls. IVD status was quantified via the ratio of IVD to vertebral body height (IVD hypertrophy) and ratio of signal intensity in the nucleus to that in the annulus signal (IVD nucleus hydration) on sagittal T2‐weighted MRI. P‐values were adjusted via the false discovery rate method to mitigate false positives. In examining the whole collective, co…
Exercise for the intervertebral disc : a 6-month randomised controlled trial in chronic low back pain
2020
Background context Muscle, bone and tendon respond anabolically to mechanical forces. Whether the intervertebral disc (IVD) can benefit from exercise is unclear. Purpose To examine whether exercise can beneficially affect IVD characteristics. Study design/setting This is a single-blinded 6-month randomised controlled trial (ACTRN12615001270505) in an exercise and physiotherapy clinic. Patient sample Forty patients with chronic non-specific low back pain (NSCLBP) are included in this study. Outcome measures The primary outcome was lumbar IVD T2 time (MRI). Secondary outcomes included IVD diffusion coefficient and IVD expansion with short-duration lying. Methods Twenty patients progressively …
