Fig. 1. Anteroposterior views for femoral periprosthetic fracture classification. Type I: simple transverse two-part fracture which involves fracture lines directly connected to the anterior flange of the femoral component and extending upon it. Type II: fracture with an oblique or reverse-oblique fracture line involving the anterior flange of the femoral component. Type III: relatively less comminuted fracture well below the anterior flange or medially comminuted fracture. Type IV: transverse fracture occurring around the tip of the stem extension attached to the revision implant. Type V: fracture with “shattered” distal fragments that do not have any recognizable main fragment with an unstable implant.
