conclusions application of pedicular screw in unstable upper and middle thoracic spine fractures is an effective method that can correct kyphotic deformity and anterolisthesis and improve neurologic deficit. background treatment of unstable upper and middle thoracic spine fractures remains controversial. there is no consensus regarding optimal treatment. objectives in this study, we evaluated t...

background: cervical spine sustains most of thevertebral column injuries, among other injuries, the disc degeneration and damage that lead to replacement of the damaged disc with cage or artificial disc. methods: the c4 to c6 vertebrae of a normal subject and a person with interbody fusion cage were 3d modelled and then analyzed using finite element method. the results of maximum stress and str...

The initial evaluation and management of cervical spine injuries is of critical importance because of the impact of early treatment and management on the patient's eventual outcome. The devastation and cost of missing even one unstable cervical spine fracture is tremendous. The existence of patients with an unsuspected cervical spine fracture who have few, if any, symptoms and/or signs of an in...

Dendritic spines, the site of most excitatory synapses in the brain, are lost in Alzheimer's disease and in related mouse models, undoubtedly contributing to cognitive dysfunction. We hypothesized that spine loss results from plaque-associated alterations of spine stability, causing an imbalance in spine formation and elimination. To investigate effects of plaques on spine stability in vivo, we...

The German Shepherd is among the breeds most prone to pathologies of lumbosacral spine. aim study was examine how presence spine pathology affects shape lumbar and dimensions individual vertebrae. Mathematical analysis consisted three measurements for each vertebra. Based on analysis, it concluded that there a correlation between height first five vertebrae occurrence transitional vertebra (LTV...

in pott’s disease (tuberculous spondylitis), involvement of two separate levels of spine is rare. attention to stability of spine prevents delayed progressive kyphosis. a 12-year-old girl presented with neck pain, tenderness and swelling imaging showed cl—c2 and t9-t10 and destruction. mild spastic paraparesis was noticed. preoperative diagnosis was metastasis. t9, t10 and t11 laminectomy and c...

Forestry workers are exposed occupationally to a number of harmful or harmful factors in their working environment (whole body and hand-arm vibration, acoustic and infrasonic noise, biohazards, musculoskeletal loads and other) that may cause a variety of workrelated or occupational diseases (e.g. vibration syndrome, noiseinduced hearing loss, hand-arm, infectious and parasitic diseases, allergi...
