Abstract:
Intertrochanteric femoral fractures are common in clinical practice and the key to treatment is timely stable fixation and early rehabilitation to prevent bedridden complications. At present, the failure of common internal fixation system in the treatment of unstable intertrochanteric femoral fractures is not rare. The authors think that for the normal anatomical type of leverage structure of human proximal femur, pivot can bear weight and complete multidirectional activities because its pivot is close to the center of the body. The intertrochanteric femoral fractures destroyed the trabecular structure on the tension side and pressure side. At the same time, the physiological lever of the proximal femur was destroyed. The cause for the failure of the existing internal fixation is the inability to reconstruct the physiological pivot. Based on the anatomical and biomechanical characteristics of the proximal femur, the author reviewed the previous literatures and analyzed the problems in the treatment of intertrochanteric femoral fractures, and for the first time raised the " lever-pivot balance" theory for the treatment of intertrochanteric femoral fractures. This theory opens a new way for solving the problems in treatment of intertrochanteric femoral fractures.
