Technical skill acquisition is an essential component of neurosurgical training. Educational theory suggests that optimal learning and improvement in performance depends on the provision of objective feedback. Therefore, the aim of this study was to develop a vision-based framework based on a novel representation of surgical tool motion and interactions capable of automated and objective assessment of microsurgical skill. ⋯ Automated and objective analysis of microsurgery is feasible using a mask region convolutional neural network, and a novel tool motion and interaction representation. This may support technical skills training and assessment in neurosurgery.

This study aimed to analyze craniocervical sagittal balance parameters in an asymptomatic population revealing the interaction of craniocervical compensation with the horizontal gaze and to identify a new parameter that can be evaluated more easily with the horizontal gaze. ⋯ The factors affecting horizontal gaze are C2S, C2-7 lordosis, O-C2 lordosis, and C2-7 SVA. C2S can be used as an indicator of the horizontal gaze in preoperative surgical planning and postoperative evaluation.

It is difficult to correctly identify the ruptured aneurysm in patients with multiple intracranial aneurysms. Here, we investigated the clinical characteristics of ruptured intracranial aneurysms in such patients. ⋯ The results of this study indicate that the aspect ratio is the most predictive factor of a ruptured intracranial aneurysm in patients with multiple intracranial aneurysms.

Giant paraspinal thoracic schwannomas (GPTSs) are benign, slow-growing, encapsulated lesions. They can be intracanalicular, span more than 2 vertebral bodies, and/or have a foraminal component with extraspinal extension >2.5 cm. They pose surgical challenges because of the often unfamiliar complex regional anatomy. We report the largest series of GPTSs and discuss regional surgical strategies for tumors in the thoracic spine. ⋯ A number of approaches are available to resect GPST in specific locations in the thoracic spine. Total resection is achievable despite complex regional anatomy, location, and tumor extension but often requires anterior or combined approaches.

To analyze artificial intelligence image-assisted knee ligament injury repair and femoral nerve block analgesia after surgery. ⋯ The artificial intelligence image-assisted diagnosis system for analysis and processing of multiparametric magnetic resonance images is useful for clinical decision making, reducing physicians' labor intensity, improving efficiency, and lowering the rate of misdiagnosis.
