Objective: To evaluate the effect of 3d printed models on surgical pre-operative planning of complex spinal deformities.
Methods: In our study, five orthopedic surgeons made surgical planning of 5 patients with severe spinal deformity in three conditions: X-ray with computer tomography (X-ray-CT), 3D-computed tomography (3dCT), and 3d printed spine models. Operation plans were examined according to the level and number of instrumentations, osteotomy level, and time required for decision-making.
Results: X-ray-CT, 3dCT, and 3d modeling methods were compared, and no statistically significant difference was observed in the number of screws and osteotomy score to be used in operation. The time required for decision ranking is 3d Model, 3d CT, and Xray-CT.
Conclusions: 3d printed models do not influence the operative plan significantly; however, it reduces surgical planning time at pre-op duration, and those models gave some opportunities to practice with implants on a patient's 3d spine model. .

Background: Postoperative fever (POF) is a common occurrence in patients undergoing major surgery, presenting challenges and burdens for both patients and surgeons yet. This study endeavors to examine the incidence, identify risk factors, and establish a machine learning-based predictive model for POF following surgery of oral cancer.
Methods: A total of seven hundred and twenty-seven consecutive patients undergoing radical resection of oral cancer were retrospectively investigated.

The neuromuscular junction shows several degenerative changes with aging, resulting in a reduction of transmission efficacy. These changes, paired with low-grade chronic inflammation, were considered triggers of the aging muscle processes. The main objective of this study is to assess the role of leukocyte count-derived ratios, nerve conduction velocity (NCV), and compound muscle action potential (CMAP) in determining time-dependent reduction in lower limb muscle explosive strength, a condition that has been defined as powerpenia.

Objectives: This study aims to investigate the prognostic value of Temporal Muscle Thickness (TMT) in Chinese patients with newly diagnosed isocitrate dehydrogenase (IDH) wild-type glioblastoma.
Methods: Data were retrospectively collected from patients with isocitrate dehydrogenase wild-type genotype glioblastoma, who underwent surgical treatment and concurrent chemoradiotherapy at our center between May 2019 and May 2023. Multi-model and multivariate Cox regression were used to examine factors associated with overall and progression-free survival.

Symmetry is integral for the balance and function of the craniofacial complex and making precise diagnosis of asymmetric craniofacial structures is crucial for treatment planning. This study focuses on maxillomandibular asymmetry, examining its impact on condylar resorption and trabecular bone morphology changes following orthognathic surgery. Cone-beam computed tomography (CBCT) scans of patients with and without asymmetry were analyzed pre- and post-surgery.

A nulliparous female presented with lower abdominal pain, initially diagnosed as incisional scar hernia, which was repaired. However, her pain persisted despite unremarkable radiology imaging. She was then diagnosed with anterior cutaneous nerve entrapment syndrome (ACNES) and underwent a right-sided ilioinguinal and iliohypogastric nerve block.
