On the radiographs, a fracture in between the 2 modular parts of the stem was seen (Figure 2). The nonunion of the trochanter was debrided and fixed with a hooked plate (proximal conical spout Revitan 75 mm, Biolox Delta Ceramic femoral head 28 mm medium, Trofix Trochanter Fixation plate large head 150 mm) (Figure 2).
