INTRODUCTION Biomechanical studies of spine range of motion (RoM) and electromyography (EMG) typically focus on the lumbar region. The thoracic spine remains a topic less investigated in the literature, especially in terms of complex/relative motion coupled with EMG patterns. Research on complex motion patterns of the thoracic spine is directed towards kinematic measures only [1, 2] and usually...

BACKGROUND Coronary artery calcification (CAC) is highly prevalent among dialysis patients and is associated with increased cardiovascular and all cause mortality. Magnesium (Mg) inhibits vascular calcification in animal and in-vitro studies but whether the same effect occurs in humans is uncertain. METHODS A single centre cross-sectional study of 80 prevalent peritoneal dialysis (PD) patient...

background: ankylosing spondylitis (as) is an inflammatory rheumatic disease that leads to a progressive ankylosis of vertebras and ossification of paravertebral ligaments. bone loss and osteoporosis are amongst the important complications of as, treatment of which is a challenging issue. objectives: this study aimed to clarify the effect of alendronate on the prevention of bone loss in patient...

This study was designed to observe the clinical outcome of anterior versus posterior instrumentation in the treatment of Pyogenic vertebral osteomyelitis of the lumbar spine. Twenty-three patients underwent either anterior (anterior fixation group) or posterior fixation (posterior fixation group) combined with a single-stage anterior radical debridement and had an average follow-up of 38 months...

OBJECTIVE Nowadays, the occurrence of brown tumor lesions or osteitis fibrosa cystica caused by long-lasting primary hyperparathyroidism are very rare, since measuring serum calcium became available routinely in the mid-1970s. It is a tumor-like lesion that may affect the entire skeleton, often presenting with diffuse focal bone pain or by pathological fracture. METHODS We describe our experi...

MRI is commonly used to evaluate lumbar spine abnormalities in patients with symptoms such as lower back pain, leg pain, paresthesia, weakness in the legs, and claudication. Occasionally, these symptoms are caused by pathologic lesions in the cervical or thoracic spine and mistaken for those caused by lumbar spine lesions. Some pathologic lesions in the cervical or thoracic spine may be serious...

The spine is a long and slender column which supports the upper body. In the 1960s, the compressive force acting on the spine estimated by the intradiscal pressure measured in vivo was found to exceed 2600N. However the ligamentous lumbar spine is known to be unstable when subjected to compressive loads of 88 N. It is generally agreed that the ligamentous spine itself is unstable but can be sta...
