Prospective multicenter study. ⋯ The rate of poor baseline waveform derivation in spine surgery was 2% in our series. This was significantly more likely in high-risk surgery for thoracic lesions and OPLL, and in cases with preoperative severe motor deficit. In such cases, it may be preferable to use multiple modalities for IONM to derive multichannel waveforms from distal limb muscles, including the AH.Level of Evidence: 3.

Retrospective case control study. ⋯ Significant variation exists across both surgeons and hospitals in perioperative blood transfusion utilization following AIS surgery. Use of autologous blood transfusion and implementing institutional transfusion protocols may reduce unwarranted variation and potentially decrease infectious complication rates.Level of Evidence: 3.

A retrospective study. ⋯ DSSA could be easily diagnosed and divided into four subgroups according to the character of CT image, corresponding surgery strategy could receive a fine clinical result.Level of Evidence: 4.
