The vertebral column is built from alternating bony vertebrae, interconnected with fibrocartilagenous discs and diarthrodial facet joints. In total 33 vertebrae (7 cervical, 12 thoracic, 5 lumbar, 5 sacral and 4 coccygeal) all conform to a basic plan. With the exception of the atlas and axis, all vertebra are made of an anterior approximately cylindrical vertebral body and an arch composed of p...

background: the aim of this study was to investigate vertebral geometry changes and determine cutoff value of vertebral height to predict fractures. methods: in a cross-sectional study, 280 postmenopausal women recruited .in all subjects bone mineral density and radiog raphy of the lumbar spine performed. lateral radiographs were evaluated for identification of vertebral fractures, using a vali...

the pomegranate seed oil (pso), containing 17-α-estradiol, is one of the newly found phytosterols with synergistic health effects on estrogen related physiological conditions. herein, pso was assessed for its potential improving effects on bone characteristics in a rat model of menopausal syndrome. three month old non-pregnant female wistar rats (n = 30) were either sham-operated (sham) or ovar...

Fractures at the thoracolumbar junction are the most common spinal column fractures. Among type C fractures in the Arbeitsgemeinschaft für Osteosynthesefragen Spine Classification, cases with complete fracture-dislocations of the spinal column often result in a critical neurological deficit despite surgical treatment. We present a case of an 18-year-old man who had a complete fracture-dislocati...

background: the cervical spine is the most vulnerable part of the vertebral column and the rotational movements are the most dangerous movements which may cause damages to cervical spine. a good treatment option for the cervical disc disease is the replacement of a damaged disc with an artificial disc that has shown satisfactory clinical results. methods: the c4 to c6 vertebrae of a normal subj...

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...

OBJECTIVE To find the frequency of deformity correction, functional outcome and complications of single-stage vertebral column resection in patients with kyphotic deformity. METHODS The prospective case series was conducted at Hayatabad Medical Complex, Peshawar, and Aman Hospital, Peshawar, from January 2012 to December 2013, and comprised all patients who underwent single-stage posterior ve...

This paper proposed an automated three-dimensional (3D) lumbar intervertebral disc (IVD) segmentation strategy from Magnetic Resonance Imaging (MRI) data. Starting from two user supplied landmarks, the geometrical parameters of all lumbar vertebral bodies and intervertebral discs are automatically extracted from a mid-sagittal slice using a graphical model based template matching approach. Base...

Scoliosis is defined as an appreciable lateral deviation with axial rotation in the normally straight vertical line of the spine. Idiopathic scoliosis is a deformity which develops during a period of rapid growth and reduces after skeletal maturity. As a biomechanical approach to scoliosis, this paper presents a computer simulation method to examine the hypothesis that local asymmetric growth i...

Severe injuries to the lower cervical spine may be overlooked when the shoulders obscure this area in the lateral view. This is a familiar clinical problem and generally it is handled by pulling downward on the arms to lower the shoulders [1 -5]. One of us (D . S.) conceived a simple device with which the patient himself exerts the traction by extending his legs . This innovation has certain ad...
