Intertrochanteric fractures are very common, and internal fixation has become a consensus, which can reduce bedridden complications. Although the current internal fixation system has been gradually improved, there are still many reports of failure. Considering the structure and biomechanical characteristics of the proximal femur, the special structure of the proximal femur is maintained by tension trabecula and compression trabecula together. The effects of compression and tension trabecula disappear when intertrochanteric fractures occur, and the normal morphology of the proximal femur couldn’t be maintained. Current internal fixation can reconstruct the support structure of the proximal femur, which restores the function of compression trabecula, but neglects the function of tension trabecula. Overly relying on internal structure support is not a perfect internal fixation. Therefore, a better internal fixation should be able to reconstruct both tension and compression trabecula, ensuring tension-compression balance and joint function, maintaining the stability of the affected side and the morphology of the proximal femur. We proposed for the first time the internal fixation theory of "tension-pressure balanceable reconstruction" for the treatment of intertrochanteric fractures, aiming to provide a new direction of the internal fixation design for proximal femoral fractures and address the shortcomings of current internal fixation devices.
