Advances in the Restoration and Fixation of Lateral Femoral Wall Fracture

Hip fractures, especially intertrochanteric fractures, are more common with aging. After decades of progress, it is a general consensus to carry out internal fixation for this group of patients. However, the recent focus is on unstable intertrochanteric fractures to ensure better prognosis and prevent internal fixation failure. The lateral femoral wall, as a novel concept, is often disregarded. Many scholars have recognized that the lateral wall of the proximal femoral plays a crucial role in the stability of internal fixation for intertrochanteric fractures. In this paper, the historical evolution, definition, clinical significance, injury classification, choice of internal fixation, and possible prognosis of lateral femoral wall fracture are reviewed in order to provide clinicians strong evidence of treatment strategies.
