U Eliav, G Navon
In T1 weighted magnetic resonance imaging of brain and spinal cord in the clinical setting, the white matter (WM) appears with greater intensity than the gray matter (GM). This contrast has been assigned to differences in T1 values. In these experiments the RF pulses are too long to excite both the water and the species with restricted motion of the protons (SRMP). In in vitro studies using short RF pulses, the contrast is reversed, with greater intensity for the GM. These results raise the question of whether magnetization transfer (MT) plays a role in the contrast observed in the T1 weighting experiments...

OBJECTIVE: Laminoplasty is an effective surgical method for treating cervical degenerative disease. However, postoperative complications such as kyphosis, restriction of neck motion, and instability are often reported. Despite sufficient preoperative lordosis, this procedure often aggravates the lordotic curve of the cervical spine and straightens cervical alignment. Hence, it is important to examine preoperative risk factors associated with postoperative kyphotic alignment changes. Our study aimed to investigate preoperative radiologic parameters associated with kyphotic deformity post laminoplasty...

BACKGROUND: Bracing is the most common nonsurgical treatment for adolescent idiopathic scoliosis. Spinal braces affect glenohumeral and scapulothoracic motion because they restrict trunk movements. However, the potential spinal-bracing effects on scapular kinematics are unknown. The present study aimed to investigate the acute effects of spinal bracing on scapular kinematics in adolescent idiopathic scoliosis. METHODS: Scapular kinematics, including scapular internal/external rotation, posterior/anterior tilting, and downward/upward rotation during scapular plane elevation, were evaluated in 27 in-brace and out-of-brace adolescent idiopathic scoliosis patients with a three-dimensional electromagnetic tracking system...

BACKGROUND: Spinal motion restriction (SMR) after traumatic injury has been a mainstay of prehospital trauma care for more than 3 decades. Recent guidelines recommend a selective approach with cervical spine clearance in the field when criteria are met. MATERIALS AND METHODS: In January 2014, the Department of Health Services of the City of Los Angeles, California, implemented revised guidelines for cervical SMR after blunt mechanism trauma. Adult patients (aged ≥18 y) with an initial Glasgow Coma Scale (GCS) score of ≥13 presented to a single level I trauma center after blunt mechanism trauma over the following 1-y period were retrospectively reviewed...

BACKGROUND: Various modifications have been tested to prevent kyphosis after Bryan cervical disc arthroplasty (CDA). However, the migration of Bryan prostheses has not been systematically studied. This study investigated the cause of anterior migration (AM) and assessed the effect of AM on clinical and radiographic outcomes. METHODS: We retrospectively reviewed 46 consecutive patients who underwent modified Bryan CDA between August 2006 and December 2010. We measured functional spinal unit, angle of operative disc space, range of motion, and sagittal alignment of cervical spine preoperatively, postoperatively, and at the final follow-up, and compared these values between the AM and non-AM groups...

BACKGROUND: Lateral lumbar interbody fusion (LLIF) is a popular, minimally invasive technique that is used to address challenging multilevel degenerative spinal diseases. It remains controversial whether supplemental instrumentation should be added for multilevel LLIF. In this study, we compared the kinematic stability afforded by stand-alone lateral cages with those supplemented by bilateral pedicle screws and rods (PSR), unilateral PSR, or lateral plate (LP) fixation using a finite-element (FE) model of a multi-level LLIF construct with simulated osteoporosis...

#16
Justin B Berthold, Timothy M Burg, Ryan Paul Nussbaum
Scapular winging represents a rare phenomenon that most commonly results from nerve damage to either the long thoracic nerve, spinal accessory nerve, or, less commonly, the dorsal scapular nerve. This injury results in an abnormal scapulohumeral interaction during kinetic motion known as scapular dyskinesis. In this case report, the patient presented with scapular dyskinesis and medial scapular winging caused by overhead weight-lifting exercises, and a long thoracic nerve injury was diagnosed. Physicians are encouraged to consider long thoracic nerve damage in a patient with a history of repetitive overhead movements who presents with scapular dyskinesis and the corresponding restriction of overhead arm motions...

OBJECTIVE: Japanese Orthopaedic Association (JOA) scoring systems were developed to evaluate the neurological function of patients with cervical or lumbar degeneration. As patient-based and multi-dimensional clinical evaluation tools, these systems should be capable of reflecting the walking disability of patients. The association between JOA scores and gait parameters, however, are not well characterized. The purpose of this study was to determine the correlations between JOA scores and gait parameters of patients with cervical spondylotic myelopathy (CSM) and lumbar intervertebral disc herniation (LDH)...
