Osteoporosis is the most common metabolic disease of the skeletal system and is characterized by impaired bone strength. This translates into an increased risk of low-energy fractures, which means fractures caused by disproportionate force. This disease is quite insidious, its presence is usually detected only at an advanced stage, where treatment with pharmaceuticals does not produce sufficient results. It is obligatory to replace the weakened bone with an implant. For this reason, it is necessary to look at the possibilities of surface modification used in tissue engineering, which, in combination with the drugs for osteoporosis, i.e., bisphosphonates, may constitute a new and effective method for preventing the deterioration of the osteoporotic state. To achieve this purpose, titanium implants coated with magnesium or zinc zeolite were prepared. Both the sorption and release profiles differed depending on the type of ion in the zeolite structure. The successful release of risedronate from the materials at a low level was proven. It can be concluded that the proposed solution will allow the preparation of endoprostheses for patients with bone diseases such as osteoporosis.
骨质疏松症是骨骼系统最常见的代谢性疾病,其特征是骨强度受损。这转化为低能量骨折风险增加,低能量骨折是指由不成比例的外力导致的骨折。这种疾病相当隐匿,通常只有在晚期才会被发现,此时药物治疗效果不佳。必须用植入物替换弱化的骨骼。因此,有必要研究组织工程中使用的表面改性可能性,其与治疗骨质疏松症的药物(即双膦酸盐)相结合,可能构成一种预防骨质疏松状态恶化的新的有效方法。为实现这一目的,制备了涂覆有镁或锌沸石的钛植入物。吸附和释放曲线因沸石结构中的离子类型而异。已证明材料能以低水平成功释放利塞膦酸盐。可以得出结论,所提出的解决方案将能够为患有骨质疏松症等骨骼疾病的患者制备假体。
