To investigate the quality of life outcomes following surgical treatment of patients with coexisting multiple sclerosis (MS) and cervical stenosis with associated myelopathy (CS). ⋯ Patients in the control cohort had clinically and statistically significant improvements in QALY outcomes. Those in the MS cohort averaged no change in QALY. However, only a minority of MS/CS patients had worsening QALY following surgery, and as such surgery may still be considered for these patients. It is imperative that there are preoperative discussions with the MS/CS patient regarding the likelihood that surgery will only provide limited, if any, improvements in QOL.

To determine the role of dynamic cervical implant (DCI) replacement for single-level degenerative cervical disc disease in Chinese patients. ⋯ DCI provided elastic dynamic stability for the targeted segment, and restored and sustained intervertebral space height and ROM of the cervical spine.

To report the surgical technique and preliminary clinical results for the treatment of basilar invagination (BI) with atlantoaxial dislocation (AAD) by posterior C1-C2 pedicle screw and rod instrument. ⋯ This C1-C2 pedicle screw and rod instrument is a promising technique for the treatment of BI with AAD.

Comparative Study
Comparison of neck movement smoothness between patients with mechanical neck disorder and healthy volunteers using the spectral entropy method.
Mechanical neck disorder is one of the most common health issues. No related observations have applied spectral entropy to explore the smoothness of cervical movement. Therefore, the objectives were to ascertain whether the spectral entropy of time-series linear acceleration could extend to estimate the smoothness of cervical movement and compare the characteristics of the smoothness of cervical movement in patients with mechanical neck pain (MND) with healthy volunteers. ⋯ The spectral entropy would be suitable to discriminate the smoothness of cervical movement between patients with MND with healthy volunteers and demonstrated patients with MND had significantly less smooth cervical movement.

To assess whether perioperative allogenic blood transfusions in patients undergoing surgical treatment for spinal metastases independently influence patient survival. ⋯ The results of the present study support that perioperative blood transfusion of <5 units does not decrease survival in patients operated for spinal metastases. Transfusion of 1-2 units seems to be associated with increased 12-month survival. Future studies should assess if a liberal transfusion regime can be applied to this group of patients; thereby, prioritizing early postoperative mobilization.
