Severe cervical kyphosis (CK) in neurofibromatosis type 1 (NF-1) is associated with a high risk for progression and neurologic impairment in children. We present our surgical technique and mid-term outcomes of uninstrumented anterior tibial strut grafting for severe CK secondary to NF-1. ⋯ In children with severe CK secondary to NF-1, cervical distraction and immobilisation with a HV followed by uninstrumented anterior tibial strut grafting and posterior bone grafting, provided spinal fusion and stability without increasing the risk of neurological injury and donor site morbidity. The reported surgical technique appears to be a valuable tool in the armamentarium of the spinal surgeon.

This article aims to provide a comprehensive review of the management challenges associated with Spinal Phosphaturic Mesenchymal tumors (PMTs) and evaluates the surgical management outcomes for this rare entity linked to Tumor-induced osteolysis. The primary objective of this study is to enhance the familiarity of treating physicians with the clinical features, diagnosis, and treatment options for Spinal PMTs. ⋯ Spinal PMTs play a significant role in Tumor-induced osteolysis, warranting timely and accurate diagnosis. Although diagnosing Spinal PMTs presents challenges, surgical management has proven to yield favorable outcomes, effectively alleviating symptoms and restoring phosphate levels. A multidisciplinary approach and continued vigilance are essential in ensuring early diagnosis, effective treatment, and long-term monitoring for patients affected by spinal PMTs.

To identify the clinical and radiological outcomes in the coronal and sagittal planes after treatment of congenital complex lumbosacral hemivertebrae (LSHV) with or without posterior concave reconstruction. ⋯ Posterior column reconstruction with insertion of a concave cage may achieve a higher correction rate of large lower lumbar lordosis and lumbosacral coronal deformity, attain better sagittal balance, and have fewer complications related to implant failure than posterior-only hemivertebra resection in patients with congenital LSHV.

Multicenter Study
Deep learning-based high-accuracy detection for lumbar and cervical degenerative disease on T2-weighted MR images.
To develop and validate a deep learning (DL) model for detecting lumbar degenerative disease in both sagittal and axial views of T2-weighted MRI and evaluate its generalized performance in detecting cervical degenerative disease. ⋯ The proposed DL model can automatically detect lumbar and cervical degenerative disease on T2-weighted MR images with good performance, robustness, and feasibility in clinical practice.

Radiological degenerative phenotypes provide insight into a patient's overall extent of disease and can be predictive for future pathological developments as well as surgical outcomes and complications. The objective of this study was to develop a reliable method for automatically classifying sagittal MRI image stacks of cervical spinal segments with respect to these degenerative phenotypes. ⋯ Class imbalance in the training data and label noise made it difficult to achieve high predictive power for underrepresented classes. This shortcoming will be mitigated in the future versions by extending the training data set accordingly. Nevertheless, the classification performance rivals and in some cases surpasses that of human raters, while speeding up the evaluation process to only require a few seconds.
