We report the first case of a combined bony and soft tissue Chance fracture in the thoracic spine, with late presenting displacement following conservative management. Chance fractures are flexion-distraction injuries to the spine. They consist of disruption and longitudinal separation of the posterior elements of the vertebra, with the fracture extending through the pedicles and into the verte...

Lung cancer has been well documented to spread to bone and the axial skeleton after metastasis to adjacent organs. Bony metastasis is not, however, the typical presenting manifestation. The differential diagnosis for a tissue mass on the skull should warrant a workup for metastatic disease. Bony metastasis plays an important role in treatment and disease management. We report an exceptionally r...

The calcium-sensing receptor (CaSR) is the principal regulator of the secretion of parathyroid hormone and plays key roles in extracellular calcium (Ca2+o) homeostasis. It is also thought to participate in the development of cancer, especially bony metastases of breast and prostate cancer. However, the expression of CaSR has not been systematically analyzed in prostate cancer from patients with...

Nasal gliomas are rare benign congenital midline tumors composed of heterotopic neuroglial tissue. They have potential for intracranial extension through a bony defect in the skull base. Neuroimaging is essential for identifying nasal lesions and for determining their exact location and any possible intracranial extension. Computed tomography is often the initial imaging study obtained because ...

For many years, conventional fluoroscopy has been used as a guide in angiography for catheter placement before filming an angiographic series and, as such , has certainly been adequate. With the advent and increased use of interventional radiology, particularly in neuroradiology, a highquality fluoroscopic image, free of obscuring bony anatomy, is desirable. Conventional fluoroscopy, regardless...

A three-dimensional image registration technique for CT and MR studies of the cervical spine was evaluated for feasibility and efficacy. Registration by means of external fiducial markers was slightly more accurate than registration by anatomic landmarks. The interrelationships between bony (eg, neural foramina) and soft tissue structures (eg, nerve roots) in the cervical spine were more conspi...

Treatment of primary elbow osteoarthritis in the young active patient less than 50 years old presents a treatment challenge to the practicing orthopaedic surgeon. Following failure of nonoperative management, surgical goals are aimed at reducing pain and improving joint mobility from bony impingement. Arthroscopic osteocapsular arthroplasty is a viable treatment option with few post-operative l...

craniofacial fi brous dysplasia (fd) is one of three types of fd which can affect the craniofacial complex. it is the proliferation of cellular fi brous connective tissue intermixed with irregular bony trabecules. it is a developmental tumor-like condition that is characterized by replacement of normal bone. the purpose of this report is to present a rare case of craniofacial polyostotic fd tha...

For our study were available fragments of bony tissue from 24 patients (15 females and 9 males) aged between 55–82 which needed hip arthroplasty after they had undergone femural neck fractures. Biologic pieces have been fixed, then decalcified and processed by wax embedding. We noted that the spongious osseous tissue appeared as rarefied after the remoulding processes; osseous traveas grew unpl...
