BACKGROUND The subluxation construct has been a divisive term in the chiropractic profession. There is a paucity of evidence to document the subluxation. Some authors have questioned the propriety of continuing to use the term. AIM The purpose of this study is to examine current North American English language chiropractic college academic catalogs and determine the prevalence of the term sub...

OBJECTIVE To evaluate the anatomical feasibility of 3.5 mm screw into the cervical spine in the pediatric population and to establish useful guidelines for their placement. METHODS A total of 37 cervical spine computerized tomography scans (24 boys and 13 girls) were included in this study. All patients were younger than 10 years of age at the time of evaluation for the period of 2007-2011. ...

The purpose of this study was to assess the feasibility and radiographic indications of using the subaxial anterior approach for decompression and fusion at C2. Anterior exposure at C2 was difficult and associated with increased morbidity. The subaxial anterior approach is easy and familiar to spine surgeons but did not provide satisfying exposure in all patients. This article describes a serie...

Anterior transdiscal axial screw (ATAS) fixation is an alternative or supplement to the plate and screw constructs for the upper cervical spine injury. However, no existing literatures clarified the anatomic feasibility of this technique for subaxial cervical spine. Therefore, the objective of this study was to evaluate the anatomical feasibility and to establish guidelines for the use of the A...

BACKGROUND Coronal tibiofemoral (CTF) subluxation is a common finding in knee osteoarthritis (OA) which can be related to poor pain scores and tibial spine impingement. In this study we describe a new method for measuring CTF subluxation and present validation of the method using cadaveric knees. METHODS A prototype software code based on the ICP mathematical algorithm was developed to measur...

The pain of rheumatoid synovitis in the neck seems often to be modest compared with that in the hands and feet, so that problems may not become apparent till later, when the ligaments and the bones have already been damaged. Ball' has described how rheumatoid cervical spondylitis looks to the pathologist. Synovitis in the apophysial joints, in the synovial tissue adjacent to the odontoid, and i...

A multilevel contiguous fracture of the subaxial cervical spine represents the severe trauma, and anterior plate fixation with anterior transpedicular screw fixation is a new and reliable fixation pattern for the treat-ment of acute spinal cord injury (ASCI). We present a case of multilevel contiguous fractures in the lower cervical spine without obvious posterior ligamentous complex injury, bu...

OBJECTIVE The aims of this study were: (i) to determine whether the severity of post-hemiplegic shoulder subluxation in stroke patients correlates with soft-tissue injury; and (ii) to determine the shoulder subluxation measurement cut-off points that are indications for further ultrasound examination for soft-tissue injuries in these patients. DESIGN Cross-sectional study. PATIENTS A total ...

STUDY DESIGN The classification system was derived through a literature review and expert opinion of experienced spine surgeons. In addition, a multicenter reliability and validity study of the system was conducted on a collection of trauma cases. OBJECTIVES To define a novel classification system for subaxial cervical spine trauma that conveys information about injury pattern, severity, trea...

INTRODUCTION The surgical treatment of unstable cervical fractures is challenging for spinal surgeons. Unstable cervical fractures associated with spondyloarthropathy and deformities that alter function, form and stability present a greater challenge. Having multiple options to manage this difficult situation is important to all spine surgeons and the results of each case depends on the singula...
