Abstract: BACKGROUND:  Intertrochanteric fracture with medial wall injury is a common type of intertrochanteric fracture. Since the medial parietal cortex is responsible for the major mechanical conduction of the proximal femur, the classification and treatment of such injuries have been updated in clinical practice.
OBJECTIVE: Through the analysis of the fracture classification, injury mechanism and mechanics of intertrochanteric fracture with medial wall injury, to summarize the different internal fixation treatment methods, thereby providing help for the treatment of this kind of fracture.
METHODS: CNKI, WanFang, PubMed and Web of Science database were searched using “intertrochanteric fracture, femoral intertrochanteric fracture, medial wall, fracture fixation” in Chinese and English, respectively. According to the inclusion and exclusion criteria, eligible literatures were included for final analysis and review.
RESULTS AND CONCLUSION: The medial parietal cortex of the intertrochanter bears the main pressure conduction of the proximal femur, and the calcar femorale is particularly important. The common fracture types include Evans type, Jensen type, AO/ATO type, Kyle type and Muller ME type, which are of guiding significance for fractures with medial wall injury. For the treatment of intertrochanteric fractures with medial wall injury in the elderly, there is no unified view on which internal fixation method is used. The best choice of internal fixation needs to be made according to the stability of the medial wall and the basic condition of elderly patients. However, for elderly patients with unstable medial wall injury, we should first restore the continuity of the cortex and bony support to the medial wall.
