In this study, we aimed to retrospectively analyze the effects of the use of univertebral screw plates (USPs) and bivertebral screw plates (BSPs) on fusion in patients who underwent anterior cervical discectomy and fusion (ACDF). ⋯ Seventeen patients were treated using USPs and 25 patients using BSPs. Fusion was achieved in all patients who underwent BSP fixation (1-level ACDF, 15 patients; 2-level ACDF, 10 patients) and 16 of the 17 patients who underwent USP fixation (1-level ACDF, 11 patients; 2-level ACDF, 6 patients). The plate of the patient with fixation failure had to be removed because it was symptomatic. A statistically significant improvement was observed in the immediate postoperative period and at the last follow-up in terms of global cervical lordosis angle, visual analog scale score, and Neck Disability Index of all patients who underwent 1-level or 2-level ACDF surgery (P < 0.05) CONCLUSIONS: Although USPs are less costly and easier to implant, the effect of USPs and BSPs on fusion and clinical outcomes is similar. Thus, surgeons may prefer to use USPs after 1-level or 2-level ACDF.

There is currently no consensus on the appropriate timing of noninvasive positive pressure ventilation (PPV) resumption in patients with obstructive sleep apnea (OSA) after endoscopic pituitary surgery. We performed a systematic review of the literature to better assess the safety of early PPV use in OSA patients following surgery. ⋯ Early resumption of PPV in OSA patients after endoscopic endonasal pituitary surgery appears relatively safe. However, the current literature is limited. Additional studies with more rigorous outcome reporting are warranted to assess the true safety of re-initiating PPV postoperatively in this population.

Since endoscopic lumbar interbody fusion procedure has established, the insertion of cage requires a large working tube, which may lead to nerve root irritation. A novel nerve baffle was used for endoscopic lumbar interbody fusion (ELIF) and its short-term outcomes were analyzed. ⋯ Endoscopic lumbar interbody fusion using the novel baffle has more advantages in nerve protection and hidden blood loss reduction than traditional ELIF with working tube. Compared with the working tube procedure, it has similar or even better short-term clinical outcomes.

The purpose of this study is to investigate long-term changes in spinal sagittal balance after microsurgical decompression in lumbar canal stenosis (LCS). ⋯ In LCS, lumbar kyphosis improves and sagittal balance tends to improve after microsurgical decompression. However, after 5 years, adjacent intervertebral degeneration occurs more frequently and sagittal balance begins to deteriorate in about one third of cases.
