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.

Aggressive giant cell tumor (GCT) is an important subtype of GCT and is relatively rare in the spine. There is little published information regarding this subject. The objective of our study is to discuss prognostic factors for primary aggressive GCT in the spine. ⋯ Total en bloc spondylectomy together with bisphosphonate treatment could significantly decrease recurrence risk of primary aggressive GCT in the spine. Jaffe grade III was an adverse prognostic factor for recurrence, while age less than 40 years was a favorable prognostic factor.

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.

To assess the clinical effect of percutaneous vertebroplasty (PVP) in the treatment of metastatic spinal tumors in patients with posterior wall defect. ⋯ PVP can be an effective treatment for metastatic spinal tumors in patients with posterior wall deficiency; however, care should be taken to control the distribution of the bone cement due to the relatively high risk of cement leakage.

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.
