In this paper, a fully discretized bio-fidelity simulation model for biomechanical (kinematic) analysis of scoliosis for various patients was developed to analyze forces on vertebrae, loads acting on the intervertebral disc, corresponding angles between vertebrae, and tension in the spine muscles during lateral bending. It was further developed to study the movement limitation and muscle activa...

INTRODUCTION There is a scanty literature support describing the incidence, mechanism of lateral dislocations of thoracolumbar spine and its management describing the reduction techniques. Hereby we present an interesting case of extruded disc acting as buttonhole preventing the reduction of lateral dislocation of L1-L2 vertebrae and this would be the first of its variety to be described ever i...

The frequency and impact of temporomandibular joint (TMJ) disorders necessitate research in characterizing the joint's function. The 6 discal attachments have not yet been systematically characterized under tension. Understanding their role in joint function may guide our study of TMJ pathologies, including disc displacement. In the present study, a porcine model was used to characterize the at...

purpose: to report multiple astrocytic hamartomas in a patient with tuberous sclerosis (ts). patient and findings: a 16-year-old girl with ts without any ocular complaint was referred for ophthalmologic examination. she had papular rash on her face and other skin lesions elsewhere in the body which were specific for ts. multiple well-circumscribed elevated lesions characteristic of astrocytic h...

The posterior epidural migration of lumbar disc fragments is an extremely rare event with an unknown pathogenesis. To the best of our knowledge, there are no previously reported cases of a change of ordinary disc herniation into the posterior epidural migration of lumbar disc fragments as confirmed by magnetic resonance imaging (MRI). A 26-year-old male presented to our department complaining o...
