Cervical spondylotic myelopathy one of the most common diseases of the vertebral column frequently caused by degenerative processes (1). The degenerative changes that occur in the cervical spine result in compression of the spinal cord and nerve roots leading to radicular pain and numbness. Posterior surgical approaches for the management of cervical spondylosis are well established and among t...

A previously healthy 46-year-old male presented to the emergency department with the sole complaint of lower back pain after being struck by a car while walking. Physical examination revealed the patient to be hemodynamicaly stable and in moderate distress secondary to back pain. Maintaining spinal precautions, the patient was log-rolled and found to have midline lumbar spine tenderness with a ...

background brucellosis is a systemic bacterial disease transmitted from animals to humans and involves many organs and tissues. symptoms of brucellosis are protean and can be similar to many other infectious diseases. none of the symptoms are specific enough to support the clinical diagnosis. the musculoskeletal system is one of the most commonly affected organs. disease can be present with bur...

OBJECTIVE Vertebral body reconstruction after corpectomy has become a common surgical procedure. The authors describe a prospectively followed case series of patients treated with expandable cages for various indications. METHODS Sixty patients underwent single or multilevel corpectomy for degenerative stenosis (13 patients), herniated disc (7 patients), deformity (14 patients), traumatic fra...

STUDY DESIGN This study validated the three-column theory of fractures by correlating the multidirectional instabilities and the vertebral injuries to each of the three columns, using a biomechanic trauma model. OBJECTIVES The objective was to validate the three-column theory as applied to the thoracolumbar fractures. SUMMARY OF BACKGROUND DATA The widely used three-column theory of fractur...

The most commonly diagnosed tumor in the spine is metastatic carcinoma and it is often stated that primary tumors are rare in this location. In Dahlin 's series of 1,447 surgically diagnosed benign skeletal tumors, 5.0% were in the vertebral column excluding the sacrum and of 4,774 surgically diagnosed malignant tumors, 8 % (1). However, it must be borne in mind that tumors in the spine may hav...

Introduction: to investigate prevalence and underlying risk factors for vertebral fractures in male geriatric outpatients on radiographs of the thoracolumbar spine. Methods: 176 men, mean age 80 years, first‐time visiting a geriatric day hospital, underwent a comprehensive geriatric assessment, routine laboratory investigation and lateral X‐rays of the chest and lumbar spine. The presence of ve...

where M is the bending moment, F is the force applied, and D is the distance from the point of force application to the axis of rotation (moment arm length). This is perhaps best depicted in Figure 11.1. Using this equation, one can determine the bending moment applied in any given clinical circumstance. The bending moment has substantial clinical significance. The application of a bending mome...

BACKGROUND Accurate knowledge of the spinal structural functions is critical to understand the biomechanical factors that affect spinal pathology. Many studies have investigated the human vertebral motion both in vitro and in vivo. However, determination of in vivo motion of the vertebrae under physiologic loading conditions remains a challenge in biomedical engineering because of the limitatio...

BACKGROUND Approximately one-third of vertebral fractures can be clinically diagnosed. AIM To study the frequency of vertebral fractures in postmenopausal women. PATIENTS AND METHODS We recruited 555 postmenopausal women from Santiago, Chile, aged 55-84 years, who manifested interest in their bone health. All were healthy by self-declaration and by general clinical and laboratory tests and ...
