Extensive mechanical loads on the lumbar spine often lead to degenerative damages of spinal structures. In many cases surgical interventions, such as spinal fusion, are unavoidable. An appropriate method for the estimation of the mechanical effects of such interventions to adjacent vertebral segments is the mathematical computer simulation. This paper presents a 3DMultiBodySimulation(MBS-) mode...

a woman presenting with severe right lower quadrant (rlq) abdominal pain is presented here. she was evaluated for all usual cause of such pain. laboratory tests and abdominal and pelvic sonography was normal. mri revealed l1-l2 disc herniation.

conclusions a high index of suspicion is required for the early diagnosis and prompt treatment of patients with osseous tuberculosis. given the high prevalence of tuberculosis in developing countries, tuberculosis should be considered in the differential diagnosis of multifocal lytic lesions and vertebra plana, especially in children. introduction multifocal skeletal tuberculosis is a rare cond...

Anthropomorphic test devices (ATDs) should accurately depict head kinematics in crash tests, and thoracic spine properties have been demonstrated to affect those kinematics. To investigate the relationships between thoracic spine system dynamics and upper thoracic kinematics in crash-level scenarios, three adult post-mortem human subjects (PMHS) were tested in both Isolated Segment Manipulation...

The lumbar spine is a fundamental structure of the human body involved in almost any functional activity. Thus, the investigation of spine pathophysiology is of relevance for many research fields. In particular, research on spine biomechanics may provide important insights on the etiology of diseases affecting spinal tissues. More specifically, spine mechanics and biochemistry can provide cruci...

background & importance: iniencephaly is a rare cranio-cervical deformity. it belongs to neural tube defects. this disorder is characterized by a retroflexion of head, a very short neck, varying degrees of incomplete posterior closure of vertebrae and cervical and thoracic spinal synostosis. this malformation is associated with central nervous system and systemic malformations. most of patients...

conclusions pneumoventricle is rare but it can be established after spinal trauma. by awareness of such possibility, accurate diagnosis by clinical examination and imaging is essential for these types of injuries introduction the presence of air within the intracranial cavity, due to the entry of air secondary to an abnormal communication after a dural tear, is defined as pneumocephalus and int...

introduction:surgical treatment of diseases in cervicothoracic, thoracic and thoracolumbar regions can be a challenging issue. cooperation of the thoracic surgeons and spine surgeons can improve the outcomes and decrease the complications of patients who underwent these approaches.materials & methods: the participants of this study consisted of seventeenpatients suffering from different types o...

background: to determine the most important preoperative factors that affect postoperative coronal parameters of scoliotic curves.   methods: all adolescent idiopathic scoliosis (ais) patients included in the study were classified according to lenke and king classification. the fusion levels were selected according to the rigidity of the existing curves (correction less than 50%), tilt of t1 an...
