There are two main puncture methods, one is unilateral transpedicular or lateral approach, and the other is bilateral transpedicular approach. This study aims to explore the difference in efficacy between these two puncture methods in the treatment of osteoporotic spinal fractures, including surgical indicators, treatment effects, complications, etc., in order to provide a basis for clinical decision-making. Through comprehensive analysis of relevant literature, it was found that unilateral puncture has the advantages of short operation time and less bone cement usage, and bilateral puncture may have more advantages in bone cement diffusion and pain relief. The surgeon can choose the appropriate puncture method according to personal preferences and the specific situation of the patient.展开更多

The products were characterized by elemental analyses, XRD, SEM, and TG DSC respectively. The effects of polyvinylpyrrolidone on the crystal form and morphology of the as prepared CaCO3 were investigated. It was found that the aggregative shape of the produced calcium carbonate crystalline could be well controlled by adjusting the concentration of the polyvinylpyrrolidone template. This may be of important meanings to the biomimetic synthesis of novel inorganic materials.展开更多
