Using features identified in T2-weighted axial magnetic, stenosis type was determined at the maximal stenosis level, and only trefoil and triangle stenosis grade types were considered because of sufficient sample size. Intraobserver and interobserver reliability were assessed by calculating weighted kappa coefficients. Symptom severity was evaluated via the Japanese Orthopedic Association Back Pain Evaluation Questionnaire (JOABPEQ). Walking ability was assessed using the Self-Paced Walking Test (SPWT) and JOABPEQ subscales. Demographic characteristics, SPWT scores, and JOABPEQ scores were compared between patients with trefoil and triangle stenosis types.</p></sec><sec><title>Results</title><p>The mean patient age was 58.1 (standard deviation, 8.4) years. The kappa values of the MRI morphology stenosis grade types showed a perfect agreement between the stenosis grade types. The trefoil group (n=53) and triangle group (n=45) showed similar preoperative JOABPEQ subscale scores (e.g., low back pain, lumbar function, and mental health) and were not significantly different in age, BMI, duration of symptoms, or lumbar stenosis levels (all <italic>p</italic>&gt;0.05); however, trefoil stenosis grade type was associated with a decreased walking ability according to the SPWT and JOABPEQ subscale scores.</p></sec><sec><title>Conclusions</title><p>These findings suggest preoperative walking ability is more profoundly affected in patients with trefoil type stenosis than in those with triangle type stenosis.</p></sec>

<p class="abstract"><strong>Background:</strong> Lumbar canal stenosis is a clinical diagnosis. MRI is used many times for making the diagnosis. But does the severity of MRI findings co-relate with functional status?</p><p class="abstract"><strong>Methods:</strong> 50 cases of central lumbar canal stenosis were included in the study. The MRI findings and Oswestery Disability Index score were compared.<strong></strong></p><p class="abstract"><strong>Results:</strong> 50% of patients with severe ODI score had no Stenosis in the MRI. MRI findings do not co-relate with the functional severity of the disease (p=0.03).</p><p><strong>Conclusions:</strong> MRI and ODI score does not co-relate. This study reinforces the fact that one should always treat the patient and not the MRI. </p>

<sec><title>Study Design</title><p>This was a single surgeon, single center-based retrospective study with prospective data collection.</p></sec><sec><title>Purpose</title><p>To assess the correlation between T2-weighted magnetic resonance imaging (MRI) signal intensity (SI) changes and factors such as age, duration of symptoms, baseline modified Japanese Orthopedic Association (mJOA) score and to determine its prognostic value in predicting recovery after surgery.</p></sec><sec><title>Overview of Literature</title><p>Whether intramedullary cord T2-weighted MRI SI changes can predict operative outcomes of cervical myeloradiculopathy remains debatable, with only a few prospective studies analyzing the same.</p></sec><sec><title>Methods</title><p>Forty-six consecutive patients who underwent cervical myeloradiculopathy were included and were followed up for an average of 1 year. Preoperative T2-weighted MRI SI grading was performed for all patients. The correlation between MRI SI changes and age, duration of symptoms, preoperative mJOA score, and mJOA score at 1-year follow-up were analyzed.</p></sec><sec><title>Results</title><p>Fifteen patients had single-level (21.73%) or double-level (10.86%) prolapsed discs; 54.34% had degenerative cervical spondylosis with canal stenosis or multilevel disc prolapse and 13.07% had ossified posterior longitudinal ligaments. The mean age was 56.17±9.53 years (range, 35–81 years). The mean baseline mJOA score was 10.83±2.58 (range, 6–16), which postoperatively improved to 13.59±2.28 (range, 8–17; <italic>p</italic>&lt;0.001). There was a statistically significant correlation between mJOA score at 1 year and MRI T2 SI grading (<italic>p</italic>=0.017).</p></sec><sec><title>Conclusions</title><p>Patients with longer symptom durations had high grades of intramedullary cord T2-weighted MRI SI changes. Age and preoperative neurological status were not significantly correlated with the existence of intramedullary cord SI changes. However, patients without or with mild and diffuse intramedullary cord T2-weighted MRI SI changes had better postoperative neurological recovery than those with sharp and focal SI changes.</p></sec>
