Medial Buttress Plate Augmentation To Cannulated Screws In Vertical Unstable Fracture Neck Femur

Background: A sizeable shear load at the fracture site, as may occur with a vertical fracture pattern in these situations, has been correlated with a greater likelihood of internal fixation failure. Nonunion rates range from 16% to 59% for Pauwels type 3 femoral neck fractures, while osteonecrosis rates range from 11% to 86% because of the significant shear pressures involved in fixing these fractures. Any attempt to treat a femoral neck fracture that does not include anatomic reduction & stable internal fixation is destined for failure.
