To evaluate cerebrospinal fluid (CSF) flow in cervical compressive myelopathy (CCM), by both quantitative and qualitative analyses, using 3T cine phase-contrast magnetic resonance imaging (cine MRI). ⋯ Maximal CSF velocity and CSF waveform score on cine MRI decreased in CCM and was correlated with the JOA score. Thus, both quantitative and qualitative analyses using cine MRI could effectively demonstrate CSF flow alterations in CCM.

To evaluate the efficacy and safety of a new type of titanium mesh cage (NTMC) in hybrid anterior decompression and fusion method (HDF) in treating continuously three-level cervical spondylotic myelopathy (TCSM). ⋯ For cases with TCSM, HDF with the NTMC and TTMC can provide comparable radiological and clinical improvements. But application of the NTMC in HDF is of advantages in decreasing the subsidence incidence, losses of lordosis correction, VAS and NDI.

To evaluate the spatial distribution and signal intensity changes following spinal cord activation in patients with spinal cord injury. ⋯ Spinal SEEP fMRI is a powerful noninvasive method for the study of local neuronal activation in the human spinal cord, which may be of clinical value for evaluating the effectiveness of interventions aimed at promoting recovery of function using electrical stimulation.

Various modifications to standard "rigid" anterior cervical plate designs (constrained plate) have been developed that allow for some degree of axial translation and/or rotation of the plate (semi-constrained plate)-theoretically promoting proper load sharing with the graft and improved fusion rates. However, previous studies about rigid and dynamic plates have not examined the influence of simulated muscle loading. ⋯ This study demonstrated that, in the presence of simulated muscle loading (follower load), the translating plate demonstrated superior performance for load sharing compared to the rigid and rotating plates.
