Fibrous dysplasia (FD) was firstly reported by Lichtenstein in 1938 and can be divided into two main kinds of subtypes: monostotic fibrous dysplasia (MFD) and polyostotic fibrous dysplasia (PFD) with or without endocrinopathy. MFD involved in cervical vertebrae is extremely rare. Two special cases of MFD involved in cervical vertebrae were treated by anterior surgical resection and fusion with ...

The Early Cretaceous was a time of dramatic change for sauropod dinosaurs in North America. Between the Late Jurassic-aged Morrison Formation and overlying Early Cretaceous strata, there was a dramatic decline in sauropod diversity. Here, we describe a new sauropod that adds to the diversity of the Early Cretaceous, from strata that can be no older than the early Aptian, (125 Ma) some 25 millio...

INTRODUCTION The aim of this study was to assess the relationship of chronological age with cervical vertebrae skeletal maturation, frontal sinus width and antegonial notch depth and a correlation, if any, among the three variables. MATERIALS AND METHODS The samples were derived from lateral cephalometric radiographs of 80 subjects (40 males, 40 females; age range: 10 to 19 years). Cervical v...

This study aimed to determine the correlation between the volumetric parameters derived from the images of the second, third, and fourth cervical vertebrae by using cone beam computed tomography with skeletal maturation stages and to propose a new formula for predicting skeletal maturation by using regression analysis. We obtained the estimation of skeletal maturation levels from hand-wrist rad...

The aim of the study was to find a correlation between the evaluation of skeletal maturation performed by the study of cervical vertebrae maturation indicators and the evaluation obtained by the hand and wrist maturation indicators. A radiographic hand-wrist bone analysis and cephalometric cervical vertebral analysis of 100 patients (36 males and 64 females) ranging from 9 to15 years were exami...

introduction: cervical rib is relatively uncommon congenital abnormality that originates from the seventh cervical vertebrae and rarely from the sixth vertebrae. the purpose of this paper is to consider that this abnormal condition is an important cause of neurovascular compression at the thoracic outlet. methods: in this study all patients who were referred to radiology department of isfahan h...

Congenital anomalies are common in the vertebral column. Skeletal abnormalities at the cervical region may result in severe neck pain and sudden unexpected death. During the osteology demonstration of cervical vertebrae for the MBBS students, it was observed that one of axis vertebra is fused with the 3rd cervical hemivertebrae. Vertebral bodies, pedicle, lamina of C2 and C3 were fused on right...

BACKGROUND Intervertebral disc calcification is a rare condition in children; in most cases, it is asymptomatic and therefore not diagnosed. CASE REPORTS In our study, we present a case of idiopathic intervertebral disc calcification within the cervical segment, at the level of C2/C3 and C4/C5 vertebrae in a 5-year-old girl with torticollis. Basic neurological examination supplemented by X-ra...
