Anteroposterior and axial X-rays. (A,B) preoperative; (C,D) postoperative; (E,F) 4 years follow-up. A 66-year-old male with increasing pain and immobilization 5 years after THA; progressive stress shielding distally around the stem and loosening zone according to Gruen I, II and VI, VII as well as VIII, IX and XIII, XIV; no infection parameters and negative joint aspiration; stem revision with cementless short stem; in particular, in the axial view, the broader geometry of the short stem compared to the explanted stem allows sufficient bone stock and provides adequate rotational stability.
