In Brief
In patients with motor eloquent gliomas, the authors assessed the validity of risk stratification using navigated transcranial magnetic stimulation (nTMS) with diffusion tensor imaging (DTI) fiber tracking for preoperative prediction of postoperative motor outcome. Tumor-to-tract distance ≤ 8 mm and tumorous motor cortex infiltration were confirmed as major risk factors for new motor deficits in addition to fractional anisotropy value (< 0.47) and resting motor threshold (≥ 71 V/m). This bicentric, prospective analysis demonstrated the relevance to clinical decision making of nTMS/nTMS-based DTI fiber tracking for balancing the extent of resection against perioperative risk to the motor system.

This study analyzed the biomechanical effects of adding a titanium triangular-shaped sacroiliac implant to a long-segment lumbopelvic construct with S2 alar-iliac screws. The analysis showed that laterally placed devices did not significantly change local stability of the sacroiliac joint; however, the strain distribution at the lumbopelvic region was affected. These findings may help clinicians understand the in vitro biomechanical effects of supplementing adult deformity correction constructs with a sacroiliac fusion device.

Researchers investigated whether a reduction in Meyerding grade is associated with clinical outcomes after decompression and fusion for grade I degenerative lumbar spondylolisthesis. They found no association between reduction in Meyerding grade and 24-month disability, back pain, leg pain, quality of life, patient satisfaction, and cumulative reoperation rate. This study does not provide evidence to support the reduction of Meyerding grade for grade I degenerative lumbar spondylolisthesis.

The authors investigated the epidemiology and morbidity of venous thromboembolism (VTE) in pediatric patients following traumatic spinal injuries. Patients with more severe spinal injury were at greater risk for VTE development; VTE was associated with longer hospital stays and increased incidence of discharge to rehabilitation centers. This study highlights key risk factors and clinical predictors for VTE development and underscores the need to develop prophylaxis protocols for pediatric trauma patients nationwide.
