Application of bone cement to enhance internal fixation of intertrochanteric fracture

It has become a research hotspot in the field of trauma orthopedics how to fix intertrochanteric fractures effectively, especially the head-neck fragment, so that the osteoporotic fracture ends can be stabilized. In order to reduce fixation failure, application of bio-reinforced materials is another promising mothod in addition to improving the design of internal fixation. This paper reviews the research history, characteristics, current research into the biomechanics and clinical application of bone reinforced cement materials, intending to help surgeons understand the principles, surgical techniques and application scope of bone bio-reinforced materials for internal fixation.
