Comparative StudyCurrent trends in spinal arthroplasty: an assessment of surgeon practices and attitudes regarding cervical and lumbar disk replacement.
Survey study involving orthopedic and neurosurgical spine surgeons. ⋯ Although the results of this study confirm that the enthusiasm for TDA was shared by many of these respondents, it is clear that additional long-term, prospective, comparative data are required before this technology may be considered as a replacement for more traditional spinal fusion procedures.

Comparative StudyAn evaluation of information on the Internet of a new device: the lumbar artificial disc replacement.
An analysis of websites, accessible to the public, was conducted pertaining to the lumbar artificial disc replacement. ⋯ The results of this study demonstrate that much of the content of Internet-derived information pertaining to the lumbar artificial disc replacement is potentially misleading. Until long-term data are available, patients should be cautioned when using the Internet as a source for health care information, particularly with regard to the lumbar artificial disc replacement.

Comparative StudyQuantitative estimation of the recurrent laryngeal nerve irritation by employing spontaneous intraoperative electromyographic monitoring during anterior cervical discectomy and fusion.
Prospective, clinical study. ⋯ Our study indicates that laryngeal IEMG is a high-sensitivity modality that can provide real-time information and can potentially minimize the risk of operative RLN injury.

Comparative StudyLong-term follow-up after open-window corpectomy in patients with advanced cervical spondylosis and/or ossification of the posterior longitudinal ligament.
Prospective study was performed in case with cervical spondylosis and ossification of the posterior longitudinal ligament (OPLL). ⋯ Long-term follow-up indicates that OWC yields satisfactory clinical and radiologic outcomes in patients with anterior compressive cervical spondylosis and/or OPLL. OWC technique creates a more stable construct with 3-point fixation and offers better load sharing among implants and healthy vertebrae. Our observations suggest that OWC is a good surgical option for this patient group.

Comparative StudyDynamic evaluation of the spinal cord in patients with cervical spondylotic myelopathy using a kinematic magnetic resonance imaging technique.
This prospective study analyzed preoperative and postoperative dynamic changes of the spinal cord in patients with cervical spondylotic myelopathy. ⋯ Cord distances are relatively smaller at C4/5 and C5/6 levels, resulting in a narrowing of the posterior subarachnoid space with posterior cord compression in patients with cervical spondylotic myelopathy. The outcome of surgery was not correlated with the magnitude of postoperative backward shifting of the spinal cord, although the spinal cord of patients after posterior decompression moved significantly dorsally at any of the flexed, neutral, or extended spinal positions. Thus numerous factors might affect the postoperative outcomes.
