Fracture Model Preparation and Fixation

fracture, femoral neck fracture
To create Pauwels type III femoral neck fracture specimens, the femoral specimens were obtained and cut off with a hacksaw in the central part of the femoral neck at a shear angle of 70°. After anatomical reduction, group A specimens were fixed with three parallel CCSs placed in an inverted triangle pattern, group B specimens were fixed with Gamma nail, and group C specimens were fixed with Gamma nail combined with one CCS perpendicular to the fracture line. The same surgeon performed all operations. The three abovementioned internal fixation positions were verified using an X‐ray camera (Figure Photographs and radiographs of the three groups of internal fixation specimens.
