The presence of metal implants in the human body causes some dangers, which result from introducing another object into organism. There may occur a biocorrosion, which causes different modifications of implant surface.

Silver was known for its antibacterial properties as long ago as in antiquity. The silver ions have ability to join the bacteria surface. Low density of silver ions Ag+ influence the protons through the bacteria surface, which results in total destruction of the cell. Antibacterial activity of silver remains in proportion with the density of silver ions Ag+ in the environment.

The aim of the article is to present two case studies on intramedullary nails. The research included the evaluation of the type of fracture and the analysis of microstructure, chemical composition and hardness of the implant material.

The article presents the analysis of clinical operation complications after the treatment of long bones by mean of ostheosynthesis with the use of metal implants and endoprothesoplastic of hip joints.

Nowadays permanent metallic cardiovascular stents are long-term implants. The long-time presence of such an implant in human body can cause overgrowth of tissue within the treated portion of the vessel, blockage of the circulatory system and many other clinical complications, such as thrombosis, prolonged physical irritations or chronic inflammation. Therefore, in recent years, there is an interest to create biodegradable metallic...
