Summary: This study aimed to validate the simplified Chinese version of the Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) for Chinese patients with cervical spondylotic myelopathy (CSM). The results showed that the scale had good construct validity, convergent validity, internal consistency reliability, and test-retest reliability. However, there was a ceiling effect.

Summary: This study investigated the changes in brain functional network at different stages of myelopathy severity in DCM patients and developed a link prediction model to predict the progression of DCM. The results revealed differences in network connectivity in DCM patients at different stages and demonstrated the predictive capability of the link prediction model.

Summary: This study aimed to evaluate the radiographical changes and clinical outcomes after tumor resection using a posterior unilateral approach for patients with cervical dumbbell-shaped schwannoma. The results showed significant improvement in cervical sagittal alignment and clinical scores after surgery. Clear margin resection helps prevent tumor regrowth.

Summary: This study investigated the reliability, validity, and responsiveness of the JOACMEQ in mainland China for patients with OPLL, and compared post-operative outcomes between mainland China and Japan. JOACMEQ demonstrated good reliability, validity, and mild responsiveness, identifying post-operative improvements in Chinese OPLL patients and showing significantly larger improvement in postoperative quality of life compared to Japanese counterparts.

Summary: The JOA score can be used as a patient-reported outcome measure for patients with degenerative cervical myelopathy. The PRO-JOA score can also be used as a disease-specific scoring measure instead of the JOA score. Although both measures show similar trends in group analysis, they should be considered as different outcomes.

Summary: This study examined the impact factors of surgical outcomes in cervical deformity patients and found that addressing severe deformity had increased clinical weight in improving patient-reported outcomes compared to addressing severe myelopathy.

Summary: This multicenter prospective study aimed to investigate the impact of ossification spread on cervical spine function and quality of life in patients with cervical OPLL. The study found that a higher neck VAS score and a larger number of bridge formations of OPLL in the whole spine were significant predictors of adverse outcomes related to cervical spine function.

Summary: This study aimed to investigate the impact of spondylolisthesis on DCM patients, with results showing a lower functional recovery ratio in patients with spondylolisthesis postoperatively. Spondylolisthesis is common in older DCM patients and may predict more advanced degeneration and worse baseline conditions and postoperative outcomes.

Summary: The study found a significant association between cervical focal kyphosis and myelopathy severity in patients with cervical spondylotic myelopathy, especially in those without severe disc herniation. This association may have implications for determining optimal cervical focal angles in surgical planning.

Summary: This study analyzed postoperative FC changes in patients with compression cervical myelopathy and their relationship with clinical scores and spinal cord function. The results showed a reorganization of the sensorimotor cortex postoperatively and significant correlations between each FC change and clinical scores.

Summary: This study found that regardless of the severity of preoperative myelopathy, surgical decompression for CSM can lead to significant improvement in quality of life, neck disability, myelopathy score, and overall health within 3 months postoperatively. The findings of this study can help surgeons make decisions in patient selection, preoperative counseling, and expected postoperative time courses.

Summary: By utilizing a 3D-CNN combined with a de-jittering mechanism, this study proposes a hand motion analysis model for assessing the severity of cervical spondylotic myelopathy (CSM) based on 10-second grip and release (G&R) videos. With a dataset of 1500 G&R videos, collected from 750 subjects, and using the 3D-MobileNetV2 model as the classifier, the proposed model achieves a Levenshtein accuracy of 97.40% and an average GPU inference time of 3.31 seconds per video. This accuracy and speed make the model a valuable screening tool for CSM and a medical assistance tool for treatment planning.

Summary: Improvements in mJOA scores correlate weakly with improvements in NDI and EQ-5D, suggesting that changes in mJOA may not be a suitable proxy for functional and quality-of-life outcomes.

Summary: The Japanese version of the COMI-Neck is valid and reliable for Japanese-speaking patients with cervical spinal disorders. The COMI summary score showed no floor or ceiling effects preoperatively or postoperatively. Each of the COMI domains and the COMI summary score correlated well with the scores of the reference questionnaires.

Summary: The study found good inter-rater reliability of the total mJOA and its subscores, except for UE sensory function which showed moderate agreement. However, the majority of assessments differed between observers, suggesting caution in interpreting the results of this measure.
