In the current finite element analysis, Traditional Growing Rod treatment resulted in slightly better curve correction and spinal growth compared to Spring Distraction System treatment, but at the expense of much higher von Mises stresses in the rods and increased intervertebral disc stress-shielding.

This study performed an analysis of C2 dome-like expansive laminoplasty (Group Dom) and C2-7 expansive open-door laminoplasty (Group Exp). The space available for cord in Group Exp was significantly larger than Group Dom, while the visual analog scale score of Group Dom became significantly larger.
Insurance Type is Associated with Baseline Patient-Reported Outcome Measures in Patients with Lumbar StenosisCrawford, Alexander M.; Xiong, Grace X.; Lightsey, Harry M.; Goh, Brian C.; Smith, Jeremy T.; Hershman, Stuart H.; Schoenfeld, Andrew J.; Simpson, Andrew K.

Prior research suggests that sociodemographic factors influence patient-reported outcome measures (PROMs). By investigating PROMs from patients with lumbar spinal stenosis, we found that insurance type is associated with different baseline PROMs. These findings have broad ranging implications for research and healthcare policy, especially when using PROMs as measures of value.
