Meta-analysis. ⋯ The available literature remains largely inconclusive. In order to reliably inform practice in this area, there is a need for large, high-quality, multicenter RCTs with standardized reporting of outcomes, with a particular focus on outcomes relating to patient function and severe complications causing long-term morbidity.Level of Evidence: 2.

Predictors of Falls in Patients with Degenerative Cervical Myelopathy: A Prospective Multi-Institutional Study.
Prospective multicenter study. ⋯ We identified preoperative lower serum potassium level and weaker handgrip strength as significant predictors of falls in patients with DCM. Therefore, DCM patients with these risk factors should be cautious about falls and might be candidates for immediate surgical intervention.Level of Evidence: 3.

A consecutive series of patients who underwent minimally invasive spinal surgery by a single surgeon at a high-volume academic medical center were studied. ⋯ We report a 4.1% rate of return to the operating room for failed indirect decompression after LLIF for refractory radiculopathy. Graft subsidence and osteoporosis were common in these patients. All five patients who required secondary decompressive laminectomy or foraminotomy underwent stand-alone primary LLIF, and the persistent radiculopathy was consistently contralateral to the initial side of the LLIF approach.Level of Evidence: 4.

Retrospective multicenter study. ⋯ SDW is sometimes seen in Lenke type 5 patients with AIS who underwent selective TL/L fusion. SDW seemed to occur as a compensation mechanism for progressing deformity of unfused segments (thoracic curve and residual lumbar curve) to maintain coronal alignment. Preoperative T curve > 30° and SDA > 0° (lower-end vertebra as L4) were determined as risk factors for SDW occurrence.Level of Evidence: 3.
