PURPOSE: Distinguishing between benign granulmoas and adenocarcinomas is confounded by their similar visual appearance on routine CT scans. Unfortunately, owing to the inability to discriminate these lesions radigraphically, many patients with benign granulomas are subjected to unnecessary surgical wedge resections and biopsies for pathologic confirmation of cancer presence or absence. This suggests the need for improved computerized characterization of these nodules in order to distinguish between these two classes of lesions on CT scans...

PURPOSE: Recent studies suggest that cervical lordosis is influenced by thoracic kyphosis and that T1 slope is a key factor determining cervical sagittal alignment. However, no previous study has investigated the influence of cervical kyphosis correction on the remaining spinopelvic balance. The purpose of this study is to assess the effect of surgical correction of cervical kyphosis on thoraco-lumbo-pelvic alignment. METHODS: Fifty-five patients who underwent ≥2 level cervical fusions for cervical radiculopathy or myelopathy were included...

INTRODUCTION: The use of radical surgical treatments in treating congenital clubfoot is decreasing. Minimally invasive surgical treatment (MIST) is a way of treating congenital clubfoot, which is a kind of compromise between a radical surgical treatment and non-operational one. A few protocols of different authors McKay, Macnicol, Stevens, Meyer, G.W.Simons and Laaveg-Ponseti were used in the evaluation of the results. SCIENTIFIC OBJECTIVE: To determine the importance and role of groups of parameters (clinical, radiographic and functional) in the evaluation of the results in patients treated with the two methods (radical operation and MIST)...

Astroblastoma is a rare glial tumor with uncertain histopathological origin and unpredictable clinical behavior. In this report, the authors present two cases of high grade intracerebral astroblastomas. Both tumors occurred in children as supratentorial, well-circumscribed, peripheral masses. The lesions differed radigraphically; one contained a huge cystic component and heterogeneously enhancing mural nodule while the other appeared as a prominently contrastenhancing solid mass lesion. Both patients were treated with surgery and postoperative radiotherapy...

BACKGROUND: Realignment of the foot and good ligament balancing are mandatory for successful reconstruction of complex hindfoot disorders. This is why references for restoration of the normal anatomy and function are necessary when considering surgical reconstruction, such as osteotomies, arthrodeses, and total ankle replacement. However, no data are available regarding the normal anatomical dimensions on standard radiographs of the hindfoot. The purpose of this radiographic study was to define relevant and reproducible measures on lateral hindfoot radiographs and to assess their reliability...

Osteoporosis and pathological bone fractures which are its consequences are a serious health problem of today's world. The aim of this study was to check if the picture of panoramic radiographs may contribute to early risk determination of this disease. The examination was carried out in women at the age 51-69. The group consisted of female patients, in whom, due to the lasting process of osteoporosis, the distal ephiphysis of radial bone was pathologically broken. The control group consisted of women who were volunteers and agreed to be examined...

A prospective analysis of plain serial radigraphs (PSR), digital subtraction arthrography (DSA), and radionuclide bone scans (RBS) was performed in 56 cemented total hip arthroplasties to evaluate the efficacy and usefulness of each study in the diagnosis of loosening. To avoid selection bias in the evaluation of DSA and RBS, the decision to perform repeat surgery was based exclusively on the clinical history and PSR. Results of each study were compared with intraoperative assessment of the status of components and expressed in terms of sensitivity, specificity, and accuracy...

Serial cephalometric radiographs of 165 children have been used to analyze age-associated changes in the saddle angle (Ba-S-N). There are mean decreases in this angle of about 5 degrees from birth to 2 years in those with either a Class I or a Class II occlusion; later changes are slight. The mean values tend to be slightly smaller in Class I boys than in those with Class II. Generally, the means are slightly larger in boys than girls but in adults this sex difference is in the reverse direction while remaining slight...
