The purpose of this study was to investigate threshold values for classifying bone as normal or osteoporotic based on Computed Tomography (CT) Hounsfield Units (HU) and to determine if clinically applicable values could be derived to aid spine surgeons evaluating bone quality using CT. ⋯ There is variation in HU values used to differentiate normal from compromised bone quality, even after limiting studies. For patients with HU values between or near 170 or 115 HU, a DEXA scan may be warranted for further evaluation. With ongoing investigation in this area, threshold values for classifying bone quality using CT will be continually refined.

Degenerative spine disease (DSD) is increasingly prevalent due to aging populations, leading to higher surgical interventions and associated complications. This necessitates a comprehensive preoperative assessment, evaluating frailty through tools such as the modified Frailty Index 5 and modified Frailty Index 11 (mFI-5 and mFI-11). Despite the utility of mFI-5 and mFI-11 in predicting postoperative complications, these indices do not account for sarcopenia, a syndrome related to but distinct from frailty, which is associated with higher complication rates. This paper aims to retrospectively evaluate the influence of sarcopenia and frailty on postoperative adverse events in a cohort of patients who underwent posterior spine fusion for degenerative disease of the lumbar spine. ⋯ Frailty is a robust predictor of postoperative complications in DSD surgeries, while sarcopenia, appears to play a lesser role. The findings suggest that frailty alone provide a more comprehensive assessment of risk than sarcopenia.

To study the effect of percutaneous kyphoplasty (PKP) combined with microwave ablation (MWA) on pain and clinical outcomes in patients with spinal metastases. ⋯ PKP combined with MWA elevates the height of the diseased vertebrae, alleviates the symptoms of pain and dysfunction, and promotes the quality of life and physical status in patients with spinal metastases.

CaO-SiO2-P2O5-B2O3 bioactive glass-ceramics7 (BGS-7) are known for their strong integration with bone and stability and are commonly used in spinal fusions. ⋯ In multilevel ACDF, BGS-7 demonstrated fusion rates comparable to those of the allograft spacer with IBG, experiencing fewer instances of subsidence and cage fracture. Therefore, BGS-7 spacer can be safely utilized in multilevel ACDF as a substitute for traditional allograft spacers, without the need for additional IBG.

To translate and cross-culturally adapt Fukushima Lumbar Spinal Stenosis Scale into a Simplified Chinese version (FLS-25-SC), and evaluate the reliability and validity of FLS-25-SC in patients with lumbar spinal stenosis. ⋯ FLS-25-SC has been shown to have acceptable reliability and validity in patients with degenerative lumbar spinal stenosis and may be recommended for patients in Chinese mainland.
