我们研究了聚乙烯醇(PVA)水凝胶在半关节置换术中的应用。 PVA-水凝胶是使用低温结晶方法在两种不同溶剂中制备的。第一种是水和二甲基亚砜 (DMSO) 的常规混合物,第二种仅包含水。将混合在水中的PVA水凝胶(PVA-H/Water)与混合在DMSO水溶液中的PVA水凝胶(PVA-H/DMSO)的硬度和耐磨性进行了比较。结果表明,PVA-H/DMSO 和 PVA-H/Water 之间的压痕硬度没有显着差异。然而,PVA-H/DMSO的摩擦系数大于PVA-H/水的摩擦系数。在 PVA-H/水中观察到的磨损痕迹比在 PVA-H/DMSO 中少。
We have investigated the use of polyvinyl alcohol (PVA) hydrogels for hemiarthroplasty. The PVA-hydrogels were prepared in two different solvents using a low-temperature crystallization method. The first was a conventional mixture of water and dimethyl sulfoxide (DMSO), and the second comprised water only. The hardness and wear resistance of the PVAhydrogel mixed in water (PVA-H/Water) were compared with that of PVA-hydrogel mixed in a DMSO aqueous solution (PVA-H/DMSO). The results indicated no significant difference in the indentation hardness between PVA-H/DMSO and PVA-H/Water. However, the frictional coefficients of PVA-H/DMSO were larger than those of PVA-H/Water. Fewer wear tracks were observed in PVA-H/Water than in PVA-H/DMSO.
