Abstract:

The German Shepherd is among the breeds most prone to pathologies of the lumbosacral spine. The aim of the study was to examine how the presence of spine pathology affects the shape of the lumbar spine and dimensions of individual vertebrae. Mathematical analysis consisted of three measurements for each lumbar vertebra. Based on the analysis, it was concluded that there was a correlation between the height of the first five vertebrae and the occurrence of the lumbosacral transitional vertebra (LTV). It was also shown that spondylosis manifested most often with a change in the distance between

This in vitro biomechanical study reports on a new implant, called an intravertebral expandable pillar (IVEP). The implant is aimed at restoring the height and strength of collapsed vertebra after fracture in an osteoporotic patient. The hypothesis is that the IVEP can effectively restore the body height of the compressed vertebra and provide proper stiffness for the collapsed vertebra. Although the reported complication rate of percutaneous vertebroplasty by injection of polymethylmethacrylate (PMMA) is low, the sequelae are severe; other potential adverse effects of PMMA injection into the v

Object Variation in the number of lumbar vertebrae occurs in a small portion of the population. Either the fifth lumbar vertebra shows assimilation to the sacrum or the first sacral vertebra shows a lumbar configuration, resulting in 4 or 6 lumbar vertebrae, respectively.

Methods: We screened 2980 dry cadaveric specimens from an osteological collection. Pelvises were reconstructed by articulating the sacra and innominate bones. PI was measured in all specimens via lateral photographs. L6-pelvic incidence (L6PI) was also measured, by articulating L6 to the sacrum and measuring PI from the superior aspect of the L6 vertebral body.

ABSTRACT Objective: To evaluate a new treatment for split fractures through fatigue tests on a swine model. Methods: Thirty lumbar spine samples (L2-L3-L4) from swine models were divided into three test groups. The first was the control group (intact vertebrae). In the second group, a bone defect was created, similar to a coronal split fracture of the vertebral body. For this, a bone defect (osteotomy) was performed in the coronal axis of the middle third of the middle lumbar vertebral body (L3), keeping the disc-ligament structures intact. In the third group, the same procedure was performed

Abstract:

Most of the biomechanical experiments, which validate vertebral finite-element models, deal with vertebral bodies in axial compression. In standing position, gravity loads can induce bending on the last thoracic and first lumbar vertebrae. Hence, the purpose of the study was to evaluate the strength of vertebrae submitted to anterior bending. The boundary conditions were carefully assessed for further validation of finite-element models. Fifteen vertebrae (T11–L2) were tested until failure. The load was applied on the anterior part of the vertebral body and distributed to the whole vertebral b

Abstract:

The axial skeleton of all vertebrates is composed of individual units known as vertebrae. Each vertebra has individual anatomical attributes, yet they can be classified in five different groups, namely cervical, thoracic, lumbar, sacral and caudal, according to shared characteristics and their association with specific body areas. Variations in vertebral number, size, morphological features and their distribution amongst the different regions of the vertebral column are a major source of the anatomical diversity observed among vertebrates.

Object When the number of lumbar and sacral vertebrae is being assessed, variations from typical lumbosacral anatomy may confuse the practitioner, potentially leading to significant clinical errors. In this study, the authors describe the statistical variation in lumbar spine anatomy in an outpatient imaging setting, evaluate the potential implications for clinical practice based on the variation in the number of lumbar-type vertebrae identified, and recommend a method for rapidly determining the number of lumbar spine vertebral bodies (VBs) in outpatients referred for lumbar spine MR imaging.

Background: A characteristic feature of the cervical vertebrae (C1–C7) is the presence of a foramen tranversarium on the transverse process. The cervical vertebrae are the smallest in size as compared to the thoracic and lumbar vertebrae and are characterized by a foramen in each transverse process, which is not found in any other vertebra. Except for the seventh cervical vertebra, which transmits only the vertebral vein, this foramen transmits the vertebral artery, vein, and sympathetic nerves (a branch from the cervicothoracic ganglion) in all cervical vertebrae.

Abstract:

Congenital malformations such as lumbosacral transitional vertebrae and spina bifida occulta constitute unrare anomalies and could affect the symptomatology of low back pain. A transitional vertebra is characterized by elongation of one or both transverse processes, leading to the appearance of a sacralized fifth lumbar vertebra or a lumbarized first sacral vertebra. Furthermore, sacral spina bifida occulta is a developmental anomaly that corresponds to the incomplete closure of the vertebral column.
