Surgical management of lumbar spondylolisthesis requires neural decompression, stabilization, and alignment restoration. Minimally invasive spine approaches offer a wide variety of advantages for spondylolisthesis management. This intraoperative note describes the treatment of L4-L5 lumbar spondylolisthesis with lateral lumbar interbody fusion (LLIF) and percutaneous pedicle screw fixation (PSF). ⋯ LLIF with percutaneous PSF can be an effective technique for treating lumbar L4-L5 spondylolisthesis.

Comparative Study
Comparison of the Transcranial Approach and Transsphenoidal Approach Based on the Anatomical Location of Origin in Pediatric Craniopharyngiomas.
Various clinical classifications of craniopharyngiomas (CRPs) have been proposed to suggest optimal surgical planning. We aimed to evaluate the clinical outcomes of pediatric CRPs and the clinical significance of anatomical classification in relation to the diaphragm sellae. ⋯ Over time, with the adoption of EEA at our institute, the impact of anatomical classification on the surgical approach has decreased. Nevertheless, an individualized surgical approach should be employed to improve long-term outcomes and minimize complications for pediatric CRPs.

Radiation induced changes (RIC) are the most common complications observed post Gamma Knife radiosurgery (GKRS) and may be observed within 6-18 months post procedure. It has been observed that almost one-third of RICs are symptomatic and half of them are persistent. There is no way to predict which patients will develop these changes and to what extent. ⋯ Some patients may develop resistant edema and necrosis post GKRS for intracranial AVMs, which may warrant medical and surgical intervention. Serum biomarkers like VEGF and endostatin may vary in the post GKRS period and can be used to identify at-risk cases, however more studies are needed to decide on appropriate time of sampling and identify clinically relevant predictive factors.

To put forward a new index of cervical curvature evaluation - relative cervical curvature area, and a new classification of cervical spine was proposed according to the relative cervical curvature area. ⋯ The relative cervical curvature area uses the area parameter instead of the original angle parameter and distance parameter to incorporate the change of segmental curvature, which makes up for the shortcomings of the Cobb angle method that only evaluates the curvature of 2 vertebrae, and better reflects the cervical curvature. Studies have shown that relative cervical curvature area has good repeatability and diagnostic value, and found that it has a good correlation with common cervical sagittal parameters. The new classification of cervical spine makes up for the disadvantage that the angle classification method cannot distinguish between S-type and RS-type, and initially proposes to use the number of intersections and the relative absolute value area to reflect the severity of S-type.

This study aimed to establish a predictive nomogram model for recollapse of fractured vertebra after posterior pedicle screw fixation in thoracolumbar fractures (TLFs). ⋯ A clinical nomogram incorporating 4 variables was constructed to predict fractured vertebra recollapse after posterior pedicle screw fixation for TLFs. The nomogram demonstrated good calibration and discriminative abilities, which may help clinicians to make better treatment decisions.
