Solitary osteochondromas, which are the most common benign bone tumors of long bones, are rarely found in the vertebral column. A 16-year-old female patient presented with a hard palpable mass at lower lumbar region like a congenital deformity. Plain radiography illustrated a well-defined solid mass arising from the posterior elements of the L3 and ruled out any congenital anomalies. A computed...

The neck (cervical spine) is a flexible part of the human body and is particularly vulnerable to injury. Patients suspected of cervical spine injuries are often imaged using lateral view radiographs. Incorrect diagnosis based on these images may lead to serious long-term consequences. Our overarching goal is to develop a computer-aided detection system to help an emergency room physician correc...

Spondyloarthropathy has been reported among modern individuals of several species of ursid. Prehistoric cervical vertebra of black bear (Ursus americanus) recovered from an archaeological site in northwestern Oregon are fused and distorted, indicating spondyloarthropathy in this species has some time depth. Inventory of this disease among paleozoological remains may reveal unknown details of di...

The identification of the skeletal maturation stage of the cervical vertebrae has proven an important reference for orthodontic diagnosis. The aim of the present study was to determine the association between the skeletal maturation stage of the cervical vertebrae and types of malocclusion according to the age and gender of participants. A total of 361 individuals (168 males and 193 females) be...

Giant cell tumors (GCTs) of bone commonly affect a single bone. Most of vertebral lesions occur in the sacrum rather than in the spine above the sacrum. Multicentric GCTs are rare. They may occur synchronously or metachronously and therefore may be identified at the same time in different anatomic locations or at different times in different anatomic locations. Synchronous tumors reportedly occ...

Fifteen months after right lobe lobectomy with adjunctive radiation therapy for squamous cell carcinoma, a patient 53-yr-old man underwent Tc-99m depreotide chest single photon emission tomography (SPECT). In addition to two focal areas of abnormally increased uptake in the right lung, the Tc-99m depreotide SPECT showed cold areas in the middle thoracic vertebrae. Photopenic areas in the 6th an...

A case of a Schmorl's node in the cervical vertebra causing neck pain is reported. An inflammatory focus was found on histological examination of Schmorl's node indicating a possible mechanism of pain production.

OBJECTIVE This study was aimed to investigate the reliability of a computer application for assessment of the stages of cervical vertebra maturation in order to determine the stage of skeletal maturity. MATERIAL AND METHODS For this study, digital lateral cephalograms of 99 subjects (52 females and 47 males) were examined. The following selection criteria were used during the sample compositi...

The results of research into human cervical spine mechanical parameters necessary for process modelling are presented. Our tests were divided into identification of tissues mechanical features and determination of data useful for validating human cervical spine models. Mechanical properties of the whole cervical spine as well as the stiffness of ligaments and discs were identified on the basis ...
