our case was a 48-year-old man with cervical pain radiatingto the upper limbs. imaging showed an intradural tumor with extradural component encasing the vertebral artery.thetumor diagnosed asa neurinomaand had been removed surgically.the post operationmagnetic resonance imagingshowed that the tumor was completely removed andthe vertebral arterywas intact at theentire length.the goal of surgery ...

BACKGROUND Conservative treatment in the Scheuermann's kyphosis obtain, during skeletal growth, remodelling of the deformed vertebras. In a previous paper on Scheuermann's kyphosis, we have studied the geometry variations of all vertebrae included in the curve, before and after the treatment. The purpose of this study was to confirm the effectiveness of conservative treatment in Scheuermann's k...

Vertebral arteries are a system of two blood vessels through which blood is carried to the rear region of the brain. This region of the human body has to be very well supplied with blood. Blood is delivered to the brain through carotid arteries as well. Due to their position and shape, vertebral arteries are a special kind of blood vessels. They have their origin at a various distance from the ...

Congenital agenesis of lumbar vertebrae was diagnosed in a day-old female lamb based on radiology and clinical examinations. There was no neurological deficit in hindlimb and forelimb associated with standing disability. Radiography of the abdominal region revealed absence of lumbar vertebrae. Necropsy confirmed clinical and radiographic results. No other anomaly or agenesis was seen macroscopi...

A protocol has been proposed for testing seats for whiplash protection, however injury criteria have not yet been chosen. Assuming that whiplash symptoms arise from non-physiological motions of vertebral segments, we determined the ability of proposed criteria to predict peak individual vertebral displacements. Twenty-eight volunteers were subjected to rear impacts while seated in a car seat wi...

In this paper a new technique is presented that extracts the geometry of lumbar vertebral bodies from spiral CT scans. Our new multi-step segmentation approach yields highly accurate and precise measurement of the bone mineral density (BMD) in different volumes of interest which are defined relative to a local anatomical coordinate systems. The approach also enables the analysis of the geometry...

Background: Knowledge of variations in the origin of vertebral artery (VA) is indispensable to vascular surgeons. Aberrant origin of vertebral artery on either side is an uncommon finding. There are unilateral and bilateral variability in VA origin. Case presentation: We present a case of vertebral artery dissection who was found to have bilateral VAs aberrant origin. The right VA took origin ...

Vertebral artery is the first branch of subclavian artery. It merges with the same artery of the opposite side to form basilar artery and becomes one of the important source of blood supply to the brain. Variation in the origin of left vertebral artery was found in 65 year old female during magnetic resonance angiography of the neck vessels. It originated from aortic arch and was longer as ...

objectives: to compare the outcomes of prone and supine lumbar traction in patients with chronic discogenic low back pain. methods: the test was prospective and randomized control trial. the structure of trial was urban physical medicine and rehabilitation clinic. participants was included of a total of 124 subjects with chronic low back pain (lbp) and evidence of a degenerative and/or herniate...
