Carbon Fibers in Biomedical Applications

Carbon fiber (CF) consists of a multitude of unique physical, chemical and biological characteristics that can be utilized and exploited for a number of diverse applications. Being light weight, high strength, and chemically stable, so they are applied in various fields including aeronautical science and space science. Investigation of applications of carbon fibers to biomaterials was started 30 or more years ago, and various products have been developed. It is used widely in imaging equipment structures to support limbs being X-rayed or treated with radiation.

Carbon fiber implants aid fixation of extremity fractures in oncology cases

Carbon fiber-reinforced polyether­therketone or CFR-PEEK implants have been used in orthopedic surgery, and spine surgery in particular, for almost 2 decades. However, the increased use of these carbon-reinforced implants has recently occurred in orthopedic traumatology, sports medicine and oncology. Carbon-reinforced implants are made of composite materials that consist of carbon fiber sheets inlayed within a …

Spinal implants: A superior design empowered by additive manufacturing

Anterior cervical discectomy and fusion (or ACDF) surgery serves to remove herniated or degenerative spinal discs. A discectomy literally “cuts out the disc” anywhere along the spine from the neck to the low back. Along this procedure, different devices can be inserted to restore patient’s motion: Interbody fusion cage “Anterior cervical discectomy” has matured into a …

Additive manufacturing solves clear and persistent problems in orthopedics

For the production of medical devices, doctors and patients are reliant upon custom-made designs or individualized small series. The high costs of metallic biocompatible materials and their processing increase total expenses. Cobalt alloys are difficult to machine as shape complexity rises. Therefore some implants are obtained by casting or traditional metal powder processing methods, which require tooling and is costly for small or unique series. As titanium is relatively difficult to cast in complicated shapes, titanium ingots are machined.
