BACKGROUND: Ehlers-Danlos syndrome (EDS) is an inherited disorder affecting the
connective tissue. EDS can manifest with symptoms attributable to the spine or
craniovertebral junction (CVJ). In addition to EDS, numerous congenital,
developmental, or acquired disorders can increase ligamentous laxity in the CVJ
and cervical spine. Resulting abnormalities can lead to morbidity and serious
neurologic complications. Appropriate imaging and diagnosis is needed to
determine patient management and need for complex surgery. Some spinal
abnormalities cause symptoms or are more pronounced while patients sit, stand, or
perform specific movements. Positional magnetic resonance imaging (pMRI) allows
imaging of the spine or CVJ with patients in upright, weight-bearing positions
and can be combined with dynamic maneuvers, such as flexion, extension, or
rotation. Imaging in these positions could allow diagnosticians to better detect
spinal or CVJ abnormalities than recumbent MRI or even a combination of other
available imaging modalities might allow. OBJECTIVES: To determine the diagnostic
impact and clinical utility of pMRI for the assessment of (a) craniovertebral or
spinal abnormalities among people with EDS and (b) major craniovertebral or
cervical spine abnormalities among symptomatic people. DATA SOURCES: A literature
search was performed using Ovid MEDLINE, Ovid MEDLINE In-Process and Other
Non-Indexed Citations, Ovid Embase, and EBM Reviews, for studies published from
January 1, 1998, to September 28, 2014. REVIEW METHODS: Studies comparing pMRI to
recumbent MRI or other available imaging modalities for diagnosis and management
of spinal or CVJ abnormalities were reviewed. All studies of spinal or CVJ
imaging in people with EDS were included as well as studies among people with
suspected major CVJ or cervical spine abnormalities (cervical or craniovertebral
spine instability, basilar invagination, cranial settling, cervical stenosis,
spinal cord compression, Chiari malformation). RESULTS: No studies were
identified that met the inclusion criteria. CONCLUSIONS: We did not identify any
evidence that assessed the diagnostic impact or clinical utility of pMRI for (a)
craniovertebral or spinal abnormalities among people with EDS or (b) major
craniovertebral or cervical spine abnormalities among symptomatic people relative
to currently available diagnostic modalities.
