The context of this work is related to the vertebra segmentation. The method we propose is based on the active shape model (ASM). An original approach taking advantage of the edge polygonal approximation was developed to locate the vertebra positions in a X-ray image. Despite the fact that segmentation results show good efficiency, the time is a key variable that has always to be optimized in a...

INTRODUCTION Lumbosacral transitional vertebra is an anatomical variation of the fifth lumbar vertebra in which an enlarged transverse process can form a joint or fusion with the sacrum or ilium. The association of that variant with low back pain and the change in the biomechanical properties of the lumbar spine is called Bertolotti's syndrome. CASE PRESENTATION We report a case of a 40-year-...

Vertebroplasty and kyphoplasty are relatively new minimally invasive methods to treat osteoporotic or pathologic vertebra fractures. Both technics are similar in principle whereas in kyphoplasty a baloon is introduced into the vertebra to restore the height loss. Currently there are severeral studies reporting the safety and efficacy of both methods and in this report technical nuances and evid...
