Nonanatomical Reduction of Femoral Neck Fractures in Young Patients (≤65 Years Old) with Internal Fixation Using Three Parallel Cannulated Screws

Figure 1

A pattern diagram showing (a, d) anatomic reduction, (b, e) positive buttress position reduction, and (c, f) negative buttress position reduction on AP radiograph. In positive buttress position reduction, the distal fracture segment is located inferiorly-medially to the lower-lateral part of the proximal fracture segment on AP radiographs. In negative buttress position reduction, the distal fracture segment was located superiorly-medially to lower-lateral part of the proximal fracture segment on AP radiographs.
