Biomechanical allometry in hominoid thoracic vertebrae

Journal of Human Evolution, 2009
Considerable differences in spinal morphology have been noted between humans and other hominoids. Although comparative analyses of the external morphology of vertebrae have been performed, much less is known regarding variations in internal morphology (density) and biomechanical performance among humans and closely related non-human primates.

Reducing peak pressures under the saddle at thoracic vertebrae 10-13 is associated with alteration in jump kinematics

Comparative Exercise Physiology: The International Journal of Exercise Physiology, Biomechanics and Nutrition, 2018
There is little information about horse-saddle interaction at take-off for a fence, although there is potential that this could have an influence on performance. It was hypothesised that (1) maximum peak pressure under the saddle would occur in the phase

Anterior approach to the upper thoracic vertebrae

The Journal of Bone and Joint Surgery. British volume, 1989
The anterior exposure of the upper thoracic spine using standard methods is often difficult and limited. We report our experience using a technique described by Sundaresan et al. (1984) in which the medial portion of one clavicle and part of the manubrium sterni are excised. In 10 cases we found this to be a useful and safe procedure.

Chondromyxoid fibroma of two thoracic vertebrae

Skeletal Radiology, 1999
We report on a case of chondromyxoid fibroma involving two adjacent thoracic vertebrae with features of aggressive behaviour on radiographs, CT and MRI. Histology revealed typical chondromyxoid fibroma with unusually coarse calcifications. Chondromyxoid fibroma of the spine is rare, and only 30 of these tumours have been reported so far. Involvement of

Fusion of anterior thoracic vertebrae in Pleistocene ground sloths

Historical Biology, 2018
A previous study reported the fusion of spinous processes of thoracic vertebrae one and two in the ground sloth Glossotherium, proposing an injury or a congenital deformation as possible causes.

Benign osteoblastoma of a thoracic vertebra

Journal of Neurosurgery, 1980
✓ A patient with osteoblastoma of the T-11 vertebral body presented with symptoms of spinal cord compression. Six weeks after an emergency laminectomy and subtotal removal, spinal computerized tomography disclosed residual tumor, which was totally removed via a combined anterior transthoracic approach and posterior laminectomy.

A transsternal approach to the upper thoracic vertebrae

The American Journal of Surgery, 1984
An anterior surgical approach to the upper thoracic vertebrae has been described. A T-shaped skin incision is used, with the horizontal limb 1 cm above the clavicle, and the vertical limb extending in the midline over the body of the sternum. A portion of the manubrium sterni, as well as the medial third of the clavicle, is resected; the avacular ...

Auto-CA: Automated Cobb Angle Measurement Based on Vertebrae Detection for Assessment of Spinal Curvature Deformity

IEEE Transactions on Biomedical Engineering, 2023
An accurate identification and localization of vertebrae in X-ray images can assist doctors in measuring Cobb angles for treating patients with adolescent idiopathic scoliosis.

Chondrosarcoma of a thoracic vertebra.

Bulletin of the Hospital for Joint Diseases Orthopaedic Institute, 1991
Central chondrosarcoma is an uncommon primary malignancy of the axial skeleton which usually affects the posterior elements or the posterior part of a vertebral body. We present an unusual case of chondrosarcoma involving the anterior part of a thoracic vertebra with massive extravertebral extension into the posterior mediastinum. The roles of computed

An anterior surgical approach to the upper thoracic vertebrae

Journal of Neurosurgery, 1984
✓ Of the various anterior surgical approaches to the spine, exposure of the upper two thoracic vertebrae remains the most challenging. An operative approach to this region is described. The major features include resection of a portion of the clavicle and the manubrium sterni.
