Do you know what is a cerclage cable?


The surgical treatment of fractures is intended to restore the function of bones and members. In cases of trauma, during hip replacement and treatment of associated peri-prosthetic fractures, for example, it is often necessary to hold the bone or fragments of bone together to create a stable environment for healing to occur. Typically, this is done with circular metal cables or wires, with various diameters, depending on the fracture and the place to be applied. 
The technique used is called Cerclage and it allows to stabilize fractures, that are impossible to achieve with other forms of fixation. 
Despite being used in a range of applications in orthopedics as a primary method of fracture fixation, cerclage also shows several drawbacks. For instance, cerclage wires are prone to breakage and cables are subject to fatigue and fraying, releasing metallic debris into the body. Furthermore, the wire or cable can break causing an interruption of the blood supply to the bone and/or tissue irritation. 
To minimize these risks, different materials are under investigation and new safety products are emerging in the market.
