Biomechanical Evaluation of the Modified Cannulated Screws Fixation of Unstable Femoral Neck Fracture with Comminuted Posteromedial Cortex

Figure 1

Radiographs in two planes (AP and lateral) were obtained for the three groups. (a-b) FNF with intact posteromedial cortex treated with three parallel PTSs; (c-d) FNF with comminuted posteromedial cortex treated with three parallel PTSs; (e-f) FNF with comminuted posteromedial cortex treated with one PTS and two inferior FTSs.
