Multicenter Study
The safety of spine surgery in the late-stage elderly of 75 years of age or older: A retrospective multicenter study.
The objective of this study was to verify that spine surgery for late-stage elderly (LSE) (age 65-74 years) is as safe as that for early-stage elderly (ESE) (age 65-74 years). ⋯ Spine surgery even for LSE can be safely done, if perioperative risk factors are appropriately managed.

C1 lateral mass fractures (LMF) cause abnormal alignment of the upper cervical joints. Conservatively treated cases can develop into late cock-robin junction, requiring a reconstructive surgical procedure of the occipitocervical junction. Partial coronal C1 LMF could be effectively fixed with lag screws. Navigation and robot-assisted techniques have made percutaneous fixation possible and are gradually being used in the upper cervical spine. ⋯ Robot-assisted percutaneous lag screw osteosynthesis is a viable option for C1 LMF. Different approaches can be selected according to the distribution of the fracture lines. With the posterior approach, the guidewire tends to deviate from the entry point because of skiving, and the technical problems need to be further solved. Screw implant by a transoral approach is comparatively easy to achieve, but the possibly of infection exists and should be monitored.

Wound dehiscence after cervical spine surgery is a well-known complication that can be a challenge for spine surgeons to manage, especially in cases of exposed implants. However, few studies have focused primarily on this phenomenon in cervical spine surgery to date. This investigation sought to determine the frequency of wound dehiscence following posterior cervical spine surgery and identify patient-based risk factors. ⋯ The observed frequency of postoperative wound dehiscence in cervical spine surgery was 5.2%. As extended T1 fusion and dialysis may increase the risk of dehiscence after surgery, patients who display such risk factors may require additional observation and care.

Central diabetes insipidus (CDI) is the most common complication of endoscopic endonasal surgery (EES) for craniopharyngioma. However, some cases of CDI could spontaneously resolve during the follow-up period. Hence, this study aimed to determine the predictive factors for the spontaneous resolution of CDI. ⋯ Hydrocephalus at diagnosis, pituitary stalk injury, and the Hong et al HI pattern might be predictors of the spontaneous resolution of CDI following EES for craniopharyngioma.

Spontaneous low-frequency oscillations (LFOs) have been widely studied in cerebrovascular disease, but little is known about their role in moyamoya disease (MMD). The objective of this study was to assess the value of spontaneous LFOs in MMD based on wavelet analysis of near-infrared spectroscopy signals. ⋯ There were significant differences in spontaneous LFO between patients with MMD and healthy controls. The change in spontaneous LFO in MMD is related to Suzuki stage, cerebral infarction, and cognitive impairment. This might be an effective method for evaluating the severity and monitoring the progression of MMD.
