ABSTRACT
BACKGROUND: The importance of the lateral wall of the femoral trochanter in the intertrochanteric fracture has been paid more and more attention. The research on the classification of the external wall in guiding clinical operation has become a hot issue. OBJECTIVE: To review the treatment strategies of different lateral wall types of intertrochanteric fractures, and the selection of the built-in materials, provide reference and help for future clinical research. METHODS: The first author searched the Chinese database ofWanfang and China National Knowledge Infrastructure with the keywords of “intertrochanteric fracture of femur; lateral wall of femoral trochanter; fracture classification; fracture fixation, internal; implant; intramedullary fixation; extramedullary fixation; complications; elderly; prognosis”. Meanwhile, PubMed English database was retrieved with the keywords “intertrochanteric fracture of femur; lateral wall of femoral trochanter; fracture classification; fracture fixation, internal; implant; intramedullary fixation; extramedullary fixation; complications; elderly; prognosis”. The retrieval time was from May 2009 to May 2019. A total of 166 literatures were retrieved. According to the inclusion and exclusion criteria, 47 literatures were selected as the research object and summarized. RESULTS AND CONCLUSION: (1) During the surgical treatment of intertrochanteric fracture of the femur, intramedullary fixation system and extramedullary fixation system have their own advantages and disadvantages. After full analysis of lateral femoral trochanter wall classification and reasonable preoperative evaluation, it is a combination of theory and practice. Signing, correctly assessing the severity of fractures and judging the prognosis, and fully preoperative evaluation can greatly help the patient’s treatment effect and prognosis. (2) It is a basic quality of doctors and a responsible attitude towards patients to formulate different treatment plans according to their economic conditions and physical qualities. “Individualization” has become the future development trend. (3) There are still many disputes in the treatment of intertrochanteric fractures. More clinical research and data support are needed in the future to solve and improve it.
