Distal junctional kyphosis (DJK) and distal junctional failure (DJF) are known complications of adult multilevel spinal fusion surgery. Previous literature has extensively investigated proximal junctional kyphosis and proximal junctional failure, but DJK and DJF are relatively understudied. This study investigates the association between bone mineral density (BMD) and DJK/DJF via a systematic review and meta-analysis. ⋯ Patients who developed DJK/DJF had significantly lower computed tomography-measured HU as compared to those without DJK/DJF. Our findings highlight the potential importance of BMD evaluation with computed tomography prior to multilevel spine fusion surgery, though further research would be helpful to evaluate the significance of dual-energy X-ray absorptiometry-based BMD measurements on DJK/DJF development.

Cauda Equina Syndrome (CES) poses significant neurological risks if untreated. Diagnosis relies on clinical and radiological features. As the symptoms are often non specific and common, the diagnosis is usually made after a MRI scan. A huge number of MRI scans are done to exclude CES but nearly 80% of them will not have cauda equina syndrome. This study aimed to develop and validate a machine learning model for automated CES detection from MRI scans to enable faster triage of patients presenting with CES like clinical features. ⋯ This study pilots a deep learning approach for predicting CEC presence, promising improved healthcare quality and timely CES management. As referrals rise, this tool can act as a fast triage system which can lead to prompt management of CES in environments where resources for radiological interpretation of mri scans is limited.

Frailty refers to a state of weakness that can arise due to age or illnesses, and frailty predisposes individuals to several adverse health outcomes. This has been postulated to prognosticate the outcome of various surgeries, including surgeries for various spine conditions; however, no meta-analysis has validated this finding. ⋯ This study revealed that high frailty according to the modified 5-Item Frailty Index is correlated with an increased risk of readmission, extended length of hospital stay, postoperative complications, nonroutine discharge, postoperative in-hospital mortality, and reoperation following spine surgeries for any pathology of the spine.
