In Brief
The authors sought to determine if there was a difference in scoliosis outcomes between patients with Chiari malformation type I (CM-I) and scoliosis who received posterior fossa decompression (PFD) with or without duraplasty. After controlling for relevant preoperative variables, the authors found that those patients receiving duraplasty were less likely to have progression of their scoliosis compared with those who received extradural PFD, although rates of spinal fusion between the two groups were similar. This finding has implications for clinical management of patients with CM-I and scoliosis.

By analyzing a series of patients with tumors located in the nondominant perirolandic area who underwent operations with brain-mapping techniques, the authors identified clinical and imaging variables associated with asleep versus awake motor mapping in order to generate a score. The clinical validity of this score was validated in a prospective series.

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 the posteriorly placed device improved local stability of the sacroiliac joint without significantly affecting rod and screw strains at the lumbosacral junction. These findings were intended to help clinicians understand the in vitro biomechanical effects of supplementing adult deformity correction constructs with a sacroiliac fusion device.

Utilizing a national cancer registry, the authors sought to characterize the risk of secondary neoplasm development after external-beam radiation therapy (EBRT) treatment of low-grade gliomas (LGGs) in pediatric patients. After controlling for available covariates and adjusting for competing risks, EBRT was associated with an increased risk of secondary neoplasm development for pediatric survivors of LGGs. The study results have suggested that the long-term implications of EBRT should be considered when making treatment decisions for these patients.

The authors analyzed the adjacent-level mobility of single-level L3–4 cortical screw–rod (CSR) versus pedicle screw–rod (PSR) fixation with and without interbody support. The use of PSR versus CSR significantly affects mobility at the adjacent level, regardless of the type of interbody support. Biomechanical evaluations of adjacent-level mobility with different screw trajectories have not been previously reported. These findings provide useful insights for clinical decision-making based on cortical bone trajectories and outcomes, as well as for future investigations.
