STUDY DESIGN In vitro biomechanical study. OBJECTIVE Our objective was to determine the effectiveness of cervical collars and cervicothoracic orthoses for stabilizing clinically relevant, experimentally produced cervical spine injuries. SUMMARY OF BACKGROUND DATA Most previous in vitro studies of cervical orthoses used a simplified injury model with all ligaments transected at a single spin...

BACKGROUND CONTEXT The epidemiology of cervical spine fractures and associated spinal cord injury (SCI) has not previously been estimated within the American population. PURPOSE To determine the incidence of cervical spine fractures and associated SCI and identify potential risk factors for these injuries in a large multicultural military population. STUDY DESIGN Query of a prospectively co...

Introduction Giant-cell tumor of the tendon sheath (GCTTS) is part of the group of synovial tumors that can affect joints, bursas, and tendon sheaths. It is rare for GCTTS to involve the spine. When present, it is more common in the lower cervical spine. In the literature, there are only four cases described in the upper cervical spine. In this report, we describe a rare case of GCTTS in the up...

OBJECTIVE To quantify the dynamic loads and intervertebral motions throughout the cervical spine during simulated rear impacts. METHODS Using a biofidelic whole cervical spine model with muscle force replication and surrogate head and bench-top mini-sled, impacts were simulated at 3.5, 5, 6.5, and 8 g horizontal accelerations of the T1 vertebra. Inverse dynamics was used to calculate the dyna...

The aim of the study has been to evaluate the range of motion of the cervical spine in relation to the age of the participants, and to determine the dimorphic and asymmetrical differences in the range of motion in pre-determined age categories. The study involved 300 children (150 girls and 150 boys) aged from 3 to 7 years, and tensiometric electrogoniometry was used to evaluate the range of ce...

The halo body jacket and plaster Minerva body jacket have been the preferred orthoses when maximal stabilization of the cervical spine is required. This report identifies some disadvantages of these orthoses, introduces the thermoplastic Minerva body jacket (TMBJ), and discusses its advantages in the rehabilitation of patients with cervical spine instability. A preliminary roentgenographic stud...

HYPOTHESIS Trauma patients with normal motor examination results and normal cervical spine helical computed tomographic (CT) scans with sagittal reconstructions do not have significant cervical spine injury. DESIGN Prospectively collected registry data. SETTING Level II community-based trauma center. PATIENTS All patients admitted to the trauma service from January 1, 1999, to December 31...

Study Design Retrospective database analysis. Objective The purpose of this study is to investigate incidence, comorbidities, and impact on health care resources of Clostridium difficile infection after cervical spine surgery. Methods A total of 1,602,130 cervical spine surgeries from the Nationwide Inpatient Sample database from 2002 to 2011 were included. Patients were included for study base...

Neck and back pain is one of the most common musculoskeletal complaints in personnel in variable acceleration environments such as astronauts and military pilots. Ultrasound is known for dynamic imaging and diagnostic workup of the axial and appendicular skeleton, but is not currently used to image the cervical spine, the injury of which may change the biomechanics of the cervical vertebrae, wh...
