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.
