Aim: To evaluate the role of posterior dynamic stabilization (PDS) with kyphoplasty (KP) in the surgical treatment of unstable osteoporotic compression fractures, which are common in the elderly population.
Material And Methods: This study included 25 patients with osteoporotic compression fractures. KP with PDS was performed on all patients. Radiological evaluation was performed with magnetic resonance imaging, computed tomography, and plain radiographs. The vertebral kyphosis angle (VKA), local kyphosis angle (LKA), and percentage of collapse were calculated. Clinical evaluation was performed with the visual analog scale and the Oswestry Disability Index (ODI). The preoperative and postoperative clinical and radiological data were compared.
Results: The clinical and radiological parameters showed significant improvement following surgical treatment. The mean preoperative visual analog scale score of 7.78 decreased to 0.94 after 12 months. The mean preoperative ODI score of 70.33 decreased to 15.65 after 12 months. The mean preoperative VKA of 17.89° decreased to 9.22° after 12 months. The mean preoperative LKA of 9.61° decreased to 5.50° after 12 months. The mean preoperative percentage of collapse of 32.56% decreased to 19.00% after 12 months. There were no major complications.
Conclusion: KP with the PDS method offered satisfactory outcomes in the surgical treatment of unstable osteoporotic compression fractures.

Background: Proficiency in endotracheal intubation (ETI) is essential for medical professionals and its training should start at medical schools; however, large caseload may be required before achieving an acceptable success rate with direct laryngoscopy. Video laryngoscopy has proven to be an easier alternative for intubation with a faster learning curve, but its availability in medical training may be an issue due to its high market prices. We devised a low-cost 3-dimensionally printed video laryngoscope (3DVL) and performed a randomized trial to evaluate if the intubation success rate on the first attempt with this device is noninferior to a standard commercially available video laryngoscope (STVL).

Purpose: The impact of body-cavity depth on open (OLR) and laparoscopic liver resection (LLR) of segment 7 remains unclear. Therefore, we investigated the influence of body-cavity depth at the upper-right portion of the abdomen on LLR and OLR of segment 7.
Methods: In total, 101 patients who underwent segment-7 liver resection over 2010-2023 were included.

Background: Penile implant surgery is the standard surgical treatment for end-stage erectile dysfunction. However, the growing complexity of modern high-tech penile prostheses has increased the demand for more practical training opportunities. The most advanced contemporary training methods involve simulation training using cadavers, with costs exceeding $5,000 per cadaver, inclusive of biohazard fees.
