Different screw fixation placements in treating of Pauwels type III femoral neck fractures: A finite element study

Intracapsular hip fractures in the young patients are typically a high energy injury fractures which are commonly known as Pauwels type III femoral neck fractures. Artificial head replacement surgery is usually not considered for treating femoral neck fractures in such patients. The commonly used devices for fixation of vertical femoral neck fractures are multiple screws or a sliding hip screw with or without an anti-rotation screw. Size, location and length of the screws are the most effective parameters in terms of structural performance of internal fixation implants, hence the optimal configuration of the screws is necessary to be investigated to guide the clinical practice. The aim of this study was comparing an inverted triangle screw configuration with different screw fixation placements.
