Vancouver classification of periprosthetic fractures. Type A fractures are peritrochanteric fractures (subtypes AG: greater trochanter and AL: lesser trochanter). Type B fractures occur around or just below the tip of the femoral stem (subtypes B1: stable stem, B2: loose stem, B3: loose implant with substantial bone loss). Type C fractures occur well below the implant (image courtesy of Hwang KT, Kim YH (2011) Treatment of periprosthetic femoral fractures after hip arthroplasty. J Korean Fract Soc 24:121–130)
