Comparative Study Clinical Trial
Anterior cervical interbody fusion with the Zero-P spacer: mid-term results of two-level fusion.
Our aim was to compare the safety and efficacy of anterior cervical discectomy and fusion (ACDF) using the Zero-P spacer versus the plate method in patients with cervical spine spondylosis. ⋯ Clinical results with the Zero-P spacer used for two-level ACDF were satisfactory. The device is superior to the traditional plate for preventing postoperative dysphagia and avoiding possible complications associated with a plate. Prospective trials with more patients and longer follow-ups are required to confirm these observations.

To investigate the clinical efficacy and feasibility of surgical treatment for lumbosacral junction tuberculosis by one-stage posterior debridement, interbody fusion, lumbopelvic fixation, and postural drainage. ⋯ Our results suggest that one-stage posterior debridement, interbody fusion, lumbopelvic fixation, and postural drainage can be an effective and feasible treatment option for lumbosacral junction tuberculosis, offering fewer complications and a better quality of life.

China, as a rapidly developing country with the largest population including over 50,000 orthopaedic surgeons, has an increasing importance in the field of spine. However, the quantity and quality of research production in the field of spine in the major regions of China-Mainland China, Taiwan, and Hong Kong is unclear. This study aimed to investigate the contribution of China to the field of spine. ⋯ Chinese contributions to the field of spine have a significant increase during the past 10 years, particularly from Mainland China. Hong Kong had the highest quality research output in terms of mean impact factor and mean citation per article.

To investigate the differences between imaging features of spinal tuberculosis (TB) and metastatic cancer measured by dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). The presentation of TB on convention MRI may not show the typical TB signs, and they may be mis-diagnosed as malignant diseases. DCE-MRI may provide additional information to help making differential diagnosis. ⋯ DCE-MRI may provide additional information for differentiation between spinal TB and metastasis, when their manifestations on conventional imaging were similar.

To make a preliminary classification of double-layer sign according to the morphological characteristics of the ossified and central hypodense mass and clarify implications of different patterns of "double-layer sign". ⋯ OPLL patients with double-layer sign of type C is almost inevitably followed by CSF leakage after anterior decompression. For type A and B, occurrence of CSF leakage is not as high as we thought before. Pattern of double-layer sign should be a considered factor when anterior or posterior approach is chosen.
