The purpose of this research is to compare the clinical efficacy, postoperative complication and surgical trauma between anterior cervical corpectomy and fusion versus posterior laminoplasty for the treatment of oppressive myelopathy owing to cervical ossification of the posterior longitudinal ligament (OPLL). ⋯ In summary, when the preoperative canal occupying ratio < 60%, no palpable difference was tested in postoperative JOA score and neurofunctional recovery rate. But, when the preoperative canal occupying ratio ≥ 60% ACCF was associated with better postoperative JOA score and the recovery rate of neurological function compared with LAMP. Synchronously, ACCF in the cure for cervical myelopathy owing to OPLL led to more surgical trauma and more incidence of complication and reoperation. On the other hand, LAMP had gone a diminished postoperative C2-C7 Cobb angle, that might be a cause of relatively higher incidence of postoperative late neurofunctional deterioration. In brief, when the preoperative canal occupying ratio < 60%, LAMP seems to be effective and safe. However, when the preoperative canal occupying ratio ≥ 60%, we prefer to choose ACCF while complications could be controlled by careful manipulation and advanced surgical techniques. No matter which option you choose, benefits and risks ought to be balanced.

To update findings of the 2000-2010 Bone and Joint Decade Task Force on Neck Pain and its Associated Disorders (Neck Pain Task Force) on the validity and reliability of clinical prediction rules used to screen for cervical spine injury in alert low-risk adult patients with blunt trauma to the neck. ⋯ Our review adds new evidence to the Neck Pain Task Force and supports the use of clinical prediction rules in emergency care settings to screen for cervical spine injury in alert low-risk adult patients with blunt trauma to the neck. The Canadian C-spine rule consistently demonstrated excellent sensitivity and negative predictive values. Our review, however, suggests that the reproducibility of the clinical predictions rules varies depending on the examiners level of training and experience.

Observational Study
Different pedicle osteosynthesis for thoracolumbar vertebral fractures in elderly patients.
Pedicle screws' stability, especially in osteoporotic fractures, is a really problem for spinal surgeons. Nowadays, little is known about the influence of different screw types and amount of cement applied. This single-center retrospective observational study has the aim of evaluating the middle- to long-term mechanical performances of different types of screws in elderly patients with thoracolumbar fractures. ⋯ All stabilization methods showed good clinical results, but cannulated screws augmented with PMMA seem to provide better implant stability with the lowest rate of loosening. These slides can be retrieved under Electronic Supplementary Material.

To determine the prevalence, radiographic features and reporting rate of, and the association between the congenital anterior and posterior C1 arch anomalies. ⋯ Although some types of congenital C1 arch anomalies are rare, type A defects are relatively common radiological findings that are unreported approximately 45% of the time. Based on the significant association between the anterior and posterior arch defects, we propose possible mechanisms for the formation of the bipartite atlas.

To conduct a systematic review of literature to determine risk factors and preventative measures of early and persistent dysphagia after anterior cervical spine surgery (ACSS). ⋯ Adequate preoperative preparation of the patients including preoperative tracheal traction exercise and quitting smoking, proper preventative measures during surgery including maintaining endotracheal tube cuff pressure at 20 mm Hg, avoiding routine use of rhBMP-2, use of zero-profile implant, use of Zephir plate, use of new cervical retractor, steroid application, avoiding prolonged operating time, avoiding overenlargement of cervical lordosis and decreasing surgical levels, doctors ensuring knowledge of anatomy, improved surgical techniques and to comfort always are essential for preventing early and persistent dysphagia after ACSS.
