Recently, many studies revealed that frailty affects unfavorably on postoperative outcomes in lumbar spinal diseases. This study aimed to investigate the relationship between frailty and clinical outcomes while identifying risk factors associated with worse clinical outcomes following lumbar spinal surgery. ⋯ Frailty persistently affects the clinical outcome negatively before and after surgery in lumbar spinal surgery. However, as the change of the clinical outcome is not different between the frail group and the non-frail group, it is difficult to interpret whether the frail patients are vulnerable to the surgery. In conclusion, frailty is not an independent risk factor for worse clinical outcome in lumbar spinal surgery.

The reliable estimation of the vertebral body posture helps to aid a safe and effective spine surgery. The proposed work aims to present an MR to X-ray image registration to assess the 3D pose of the vertebral body during spine surgery. The 3D assessment of vertebral pose assists in analyzing the position and orientation of the vertebral body to provide information during various clinical diagnosis conditions such as curvature estimation and pedicle screw insertion surgery. ⋯ The proposed method is a fast and accurate registration method that can provide 3D information about the vertebral body. This 3D information is useful to improve accuracy during various clinical diagnoses.

To assess direct costs and risks associated with revision operations for distal junctional kyphosis/failure (DJK) following thoracic posterior spinal instrumented fusions (TPSF) for adolescent idiopathic scoliosis (AIS). ⋯ In this single-center experience, risk factors for development of DJK were greater BMI, lower post-operative thoracic kyphosis, and LIV cranial to SSV. As revision operations for DJK were significantly more costly than index operations, all efforts should be aimed at strategies to prevent DJK in the AIS population.

Scoliometry is not always included in the examination protocol of IS patients. The aim of this report is to examine the degree of correlation of Segmental Rib Index (SRI) to scoliometry, in order for SRI to be used as a surrogate of scoliometric angle of trunk rotation (ATR). ⋯ It was suggested that as long as the patients doesn't have scoliometer measurements, the SRI, could be used as a surrogate for scoliometry. It was also found that in thoracic, thoracolumbar and lumbar level, in both genders, changing from the flexed position to the standing position, the mean trunk asymmetry (TA) decreases. Therefore, if these patients had their TA measured using a scoliometer during the Adams test, their body asymmetry would have been greater than that measured using the SRI method on standing LSR. Consequently, it is evident that the significantly correlated SRI used as a surrogate for the scoliometric assessment of TA is reasonably a strong surrogate.

To determine if C2 pedicle versus pars screw type predicts change in fusion status, C2 screw loosening, cervical alignment, and patient-reported outcomes measures (PROMs) after C2-T2 posterior cervical decompression and fusion (PDCF). ⋯ There were no significant differences in fusion status, hardware complications, and radiographic and clinical outcomes based on C2 screw type following C2-T2 PCDF. Accordingly, intraoperative usage criteria can be flexible based on patient vertebral artery positioning and surgeon comfort level.
