“…Although clinically relevant correlations between acute-phase magnetic resonance imaging findings and neurological outcomes have been reported in SCI patients, no studies reporting significant correlation between magnetic resonance imaging findings and initial neurological examination results have been published to date. [17][18][19][20] Nonetheless, as diagnostic imaging technology continues to evolve, future modification of SCI syndrome definitions may occur.…”

Study design: A questionnaire survey. Objectives: To evaluate the need for the introduction of quantitative diagnostic criteria for the traumatic central cord syndrome (TCCS). Setting: An online questionnaire survey with participants from all over the world. Methods: An invitation to participate in an eight-item online survey questionnaire was sent to surgeon members of AOSpine International. Results: Out of 3340 invited professionals, 157 surgeons (5%) from 41 countries completed the survey. Whereas most of the respondents (75%) described greater impairment of the upper extremities than of the lower extremities in their own TCCS definitions, symptoms such as sensory deficit (39%) and bladder dysfunctions (24%) were reported less frequently. Initially, any difference in motor strength between the upper and lower extremities was considered most frequently (23%) as a 'disproportionate' difference in power. However, after presenting literature review findings, the majority of surgeons (61%) considered a proposed difference of at least 10 points of power (based on the Medical Research Council scale) in favor of the lower extremities as an acceptable cutoff criterion for a diagnosis of TCCS. Most of the participants (40%) felt that applying a single criterion to the diagnosis of TCCS is insufficient for research purposes. Conclusion: Various definitions of TCCS were used by physicians involved in the spinal trauma care. The authors consider a difference of at least 10 motor score points between upper and lower extremity power a clear diagnostic criterion. For clinical research purposes, this diagnostic criterion can be considered as a face valid addendum to the commonly applied TCCS definition as introduced by Schneider et al.

“…3,4 Magnetic resonance imaging is the examination of choice for the diagnosis of traumatic CCS, showing intramedullary hypersignal on T2-weighted and STIR (Short TI recovery) sequences consistent with edema, as well as lesions of ligaments and intervertebral discs. 5,6 Magnetic resonance imaging is also useful for the assessment of hemorrhage and may show the presence of prevertebral hematoma or disruption of posterior ligaments, which may suggest spinal column instability. [7][8][9] X-rays may be normal if there is no pre-existing pathology.…”

“…More recently, Miyanji et al examined the correlation between MRI parameters and 1992 ASIA/IMOSP Standards in a series of 100 individuals with cervical spine trauma of whom 76 patients had a SCI (ASIA, 1992;Miyanji et al, 2007). Using their reported data on imaging parameters from MRI studies that were obtained 24-48 h post-injury, we estimated the sensitivity and specificity of each imaging parameter for diagnosis of motor and sensory complete SCI (Miyanji et al, 2007) (Table 7).…”

The results of this study suggest that presence of cord swelling and quantitative measurement of spinal canal stenosis and cord compression are significantly correlated with the baseline ASIA motor score (Miyanji et al, 2007).…”

With the resurgence of clinical trials in spinal cord injury (SCI), there is intense interest in whether the American Spinal Injury Association (ASIA) standards are sensitive enough to discriminate neurological recovery. We conducted a systematic review to examine the psychometric properties of the ASIA Standards in assessing motor and sensory function of individuals with acute traumatic SCI. Papers, which examined the psychometric properties of the ASIA Standards, were obtained from Medline, CINAHL, and EMBASE databases (1982-2008). Of 39 publications primarily identified, 18 fulfilled the inclusion and exclusion criteria. An additional 51 publications were captured in a secondary search using the bibliographies from original articles and published reviews. The 2000 version of the ASIA Standards appear to be more reliable than the previous versions, although two prospective studies indicate that the ASIA Standards do not reliably assess children less than 4 years with SCI. Responsiveness studies indicate that (a) a detailed neurological examination using the ASIA Standards at 72 h should be obtained for comparison with subsequent neurological assessments following SCI; (b) the use of ASIA upper-and lower-extremity motor subscores instead of a single ASIA motor score is recommended; (c) further investigation of the minimal clinically important difference of the ASIA Standards is required; and (d) the functionally meaningful ASIA score threshold to document the benefit of a novel therapeutic intervention varies according to the level and severity of SCI. Although the ASIA Standards cannot be evaluated in terms of criterion validity, several studies suggested their divergent and convergent construct validity. Therefore, the ASIA Standards represent an appropriate instrument to discriminate and evaluate patients with SCI in a longitudinal manner. Nonetheless, further investigation of the ASIA Standards is recommended due to a paucity of studies focused on some key elements of the measurement responsiveness, including minimal clinically important difference.

Acute Cervical Traumatic Spinal Cord Injury: MR Imaging Findings Correlated with Neurologic Outcome—Prospective Study with 100 Consecutive Patients¹

Abstract: MSCC, spinal cord hemorrhage, and cord swelling are associated with a poor prognosis for neurologic recovery. Extent of MSCC is more reliable than presence of canal stenosis for predicting the neurologic outcome after SCI.
