A three-dimensional analysis of humeral head retroversion.
INTRODUCTION The anatomic neck of the humerus is used as a reference for the osteotomy in shoulder arthroplasty. Resection along the anterior portion of the cartilage/metaphyseal border is assumed to remove a cap of a sphere that can accurately be replaced with a spherical prosthetic implant oriented precisely to the original articular surface. The aim of this study was to determine the variabi...
متن کاملThyroid dose and dose reduction method from CT scan of head and neck
Introduction: Computed tomography (CT) consists of 11% of all imaging methods, but accounts for approximately 67% of radiation exposure due to diagnostic cases. More than one-third of all CT scans are done in the head and neck area. The thyroid gland is irradiated during CT head and neck. According to studies, this gland has the highest levels of radiation-induced cancer, and i...
متن کاملRetroversion of the humeral head in children with an obstetric brachial plexus lesion.
We undertook a prospective MRI study to measure the retroversion of the humeral head in 33 consecutive infants with a mean age of 1 year 10 months (3 months to 7 years 4 months) who had an obstetric brachial plexus lesion (OBPL). According to a standardised MRI protocol both shoulders and humeral condyles were examined and the shape of the glenoid and humeral retroversion determined. The mean h...
متن کاملCorrelation between anatomical parameters of intertubercular sulcus and retroversion angle of humeral head.
OBJECTIVE To obtain anatomical data on intertubercular sulcus of humerus, evaluate the correlation between intertubercular sulcus and retroversion angle of humeral head, to guide the positioning of torsion angle of prosthesis during total shoulder arthroplasty and provide references for shoulder prosthesis design. METHODS Using a Siemens Ultrahigh speed 64- rows multi-slices spiral CT scanner...
متن کاملThe USDA Automated Multiple-Pass Method accurately assesses population sodium intakes.
BACKGROUND Given current sodium-reduction strategies, accurate and practical methods to monitor sodium intake in the US population are critical. Although the gold standard for estimating sodium intake is the 24-h urine collection, few studies have used this biomarker to evaluate the accuracy of a dietary instrument. OBJECTIVE Our objective was to compare self-reported dietary intake of sodium...
