We report 2 cases of acute, progressive myelopathy after a fall in elderly patients who had a retroodontoid pseudotumour and extensive ossification of the anterior longitudinal ligament.

Dr. Twomey showed us, through meticulous dissections that the conventional model of a disc bulging out against a nerve root is not only very unlikely, but that mechanical compression of a nerve only produces paresthesia and numbness. Discs do bulge, but is usually contained within/around the posterior longitudinal ligament. Furthermore a mechanical model that teaches a disc pushes against a ner...

Study Design Retrospective study. Objective Minor trauma, even from a simple fall, can often cause cervical myelopathy, necessitating surgery in elderly patients who may be unaware of their posterior longitudinal ligament ossification (OPLL). The aim of this study is to determine the influence of trauma on the neurologic course in patients who have undergone surgery for cervical OPLL. Methods P...

PURPOSE To investigate the MR appearance of ossification of the posterior longitudinal ligament (OPLL) of the cervical spine. MATERIALS AND METHODS A retrospective review of MR images and conventional tomograms in 147 patients. RESULTS In the sagittal plane, proton-density images identified the ossified lesions more clearly than did T1- and T2-weighted images. All axial sequences identified...

OBJECT Ossification of the posterior longitudinal ligament (OPLL) can result in significant myelopathy. Surgical treatment for OPLL has been extensively documented in the literature, but less data exist on conservative management of this condition. METHODS The authors conducted a systematic review to identify all reported cases of OPLL that were conservatively managed without surgery. RESUL...

Mechanical properties of cervical spine ligaments are of great importance for an accurate finite element model when analyzing the injury mechanism. However, there is still little experimental data in literature regarding fresh human cervical spine ligaments under physiological conditions. The focus of the present study is placed on three cervical spine ligaments that stabilize the spine and pro...

PURPOSE The purpose of this 1-year longitudinal study is to investigate the change in flow experience among occupational therapy students (OTS). METHODS In December 2012, we prospectively recruited 97 OTS from the Department of Occupational Therapy, Kibi International University. To assess flow experience in daily life, we used the Flow Experience Checklist. RESULTS The dataset included 87 ...

BACKGROUND The sex composition of existing children has been shown to influence childbearing decision-making and behaviors of women and couples. One aspect of this influence is the preference for sons. In India, where son preference is deeply entrenched, research has normally focused on rural areas using cross-sectional data. However, urban areas in India are rapidly changing, with profound imp...

Conservative treatment is ineffective for ossification of the posterior longitudinal ligament (OPLL) in the thoracic spine, and surgical treatment is indicated for most cases, while such cases are not often experienced. In the present study, the results of surgical management involving mainly posterior decompression for this disease were evaluated clinically. The study included 9 patients (1 ma...

The purpose of this study was to evaluate the outcome of segmental anterior decompression and fusion for multilevel ossification of the posterior longitudinal ligament. Data were collected from 23 patients with multilevel ossification of the posterior longitudinal ligament. Average operative time and blood loss were 121 minutes and 201.6 mL, respectively. The Nurick score significantly decrease...
