Cervical orthoses.
A biomechanical study is presented to compare the effectiveness of three types of off-the-shelf cervical orthoses and one custom-fit collar in restricting cervical spine motion. A group of 10 normal subjects was studied. The measurements of flexion and extension, lateral side flexion and axial rotation were recorded using various measurement techniques. Interface pressures at the chin and occip...

متن کاملBiomechanical analysis of cervical orthoses in flexion and extension: a comparison of cervical collars and cervical thoracic orthoses.
The analysis of current cervical collars (Aspen and Miami J collars) and cervical thoracic orthoses (CTOs) (Aspen 2-post and Aspen 4-post CTOs) in reducing cervical intervertebral and gross range of motion in flexion and extension was performed using 20 normal volunteer subjects. The gross sagittal motion of the head was measured relative to the horizon with the use of an optoelectronic motion ...
متن کاملDo cervical collars and cervicothoracic orthoses effectively stabilize the injured cervical spine? A biomechanical investigation.
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...
متن کاملAre External Cervical Orthoses Necessary after Anterior Cervical Discectomy and Fusion: A Review of the Literature
INTRODUCTION & BACKGROUND The use of external cervical orthosis (ECO) after anterior cervical discectomy and fusion (ACDF) varies from physician to physician due to an absence of clear guidelines. Our purpose is to evaluate and present evidence answering the question, "Does ECO after ACDF improve fusion rates?" through a literature review of current evidence for and against ECO after ACDF. R...
