BACKGROUND Historically, radiographs, micro-computed tomography (micro-CT) exams, palpation and histology have been used to assess fusions in a mouse spine. The objective of this study was to develop a faster, cheaper, reproducible test to directly quantify the mechanical integrity of spinal fusions in mice. METHODS Fusions were induced in ten mice spine using a previously described technique...

Abstract Pott’s disease is a form of extrapulmonary tuberculosis (TB) affecting the spine. Approximately 10% individuals with TB will have skeletal manifestations most common area affected being spine, followed by hip and knee. Within has predilection for thoraco-lumbar region, cervical spine least affected. Here, we report case in 16-year-old child, no risk factors TB, presenting neck pain sti...

CEnVlCAL OSTEOTOM~ for severe ankylosing spondylitis involving the cervical spine is uncommon. Yet, there are occasions when one may be called upon to provide anaesthesia for such an operation. At present there are no comprehensive reports on its anaesthetic management. The largest series of cervical osteotomy was reported by Simmons of Toronto, who at the time of his report had operated on 20 ...

The pig spine is widely used as a large animal model for preclinical research in human medicine to test new spinal implants and surgical procedures. Among them, pedicle screw is one of the most common method of fixation of those implants. However, the pedicle of the porcine vertebra is not as well defined and not as large as the pedicle of the human vertebra. Therefore, the position of the scre...

vertebrae, and eleven have firm fibrous ankylosis. Fourteen still have an unstable spine though some of these are much improved. Thus fifty-one out of sixty-five (or 78 per cent) have a stable and comfortable spine. 4. The duration of treatment of these patients has been considerably less than that formerly necessary. There has been no death among patients treated by this operation. These resul...

MR imaging automated spine survey iterative scan technique (ASSIST) provides an automated subminute, submillimeter, in-plane resolution survey of the entire spine in 2 contiguous sagittal fast gradient-echo breath-hold series with computer labeling of vertebrae and disks. The technique was prospectively tested in 13 school-aged children for a wide range of clinical indications. In all cases, im...

STUDY DESIGN The motion of each cervical vertebra during simulated rear-end car collisions was analyzed. OBJECTIVES To clarify the mechanism of zygapophysial joint injury during whiplash loading. SUMMARY OF BACKGROUND DATA The zygapophysial joint is the suspected origin of neck pain after rear-end car collision. However, no studies have been conducted on the mechanisms of zygapophysial join...

osteoporosis diagnosis is usually based on examination of the hip bone and vertebrae density; however, the radius bone has gained attention recently in terms of feasibility and accessibility as it is done by portable devices with proper precision. this study aims to compare hip and spine density with radius, knowing whether radius may be an appropriate alternative for osteoporosis diagnosis. 12...

The cervical spine allows humans to perform complex motions including lateral bending, twisting, and flexion/extension. The anatomical structures of the cervical spine, such as the cervical discs, facet joints, and ligaments, are constantly under stress due to everyday activities. Sustained stress over time causes injury and degeneration in the structures of the cervical spine and the developme...

This paper presents a new method for automatic localization and identification of vertebrae in arbitrary field-of-view CT scans. No assumptions are made about which section of the spine is visible or to which extent. Thus, our approach is more general than previous work while being computationally efficient. Our algorithm is based on regression forests and probabilistic graphical models. The di...
