The advantages of fixed-angle implants are due to the design of the screws used, which results in increased axial stability, only slight periostal contact, and better seating of the implant in bone that is already damaged. These implants can be used, for example, in the long bones, the spine and the pelvis. They can be applied for the treatment of joint fractures and fractures in the vicinity of joints, and also for the treatment of such problem fractures as those close to prosthetic implants. It is not always possible to avoid secondary correction loss. It is important to differentiate technical surgical errors, such as selection of the wrong implant with consequent implant failure, and impaired fracture healing with deformation of the implant from correction loss that is not dependent on the implant system at all. A sound introduction to the use of the system to be applied can keep correction loss to a minimum.
