Application of Biodegradable Materials in Orthopedics
Journal of Medical and Biological Engineering(2019)
摘要
Purpose To compare the advantages and disadvantages of biodegradable and non-degradable implants in orthopedic fractures. Methods Recent original articles about biodegradable and non-degradable implants for fracture fixation were reviewed extensively, and a comprehensive retrospective analysis was performed. Results Standard orthopedic treatment is to use non-degradable metal implants to fixate the fracture site. This kind of treatment not only causes rejection and stress shielding, but also requires a second surgery to remove the metal implants. In addition, this kind of treatment increases physical pain and is a serious financial burden to patients. However, biodegradable implants do not require a second surgery for removal and have good biocompatibility and osteoconductivity. Conclusions Biodegradable implants do not require a second surgery for removal and have good biocompatibility and osteoconductivity. Consequently, they are an ideal treatment and are increasingly used for orthopedic surgical patients. The most common indications for biodegradable implants include craniofacial reconstruction, anterior cruciate ligament reconstruction, meniscus repair, ankle fracture treatment, and tibia and fibula fracture treatment.
