He had undergone primary total hip arthroplasty (THA) with a metal-on-metal bearing in 2007. In 2025, radiographs revealed a fracture of his 18-mm diameter extensively porous-coated, cobalt-chrome alloy femoral stem (Prodigy, DePuy Orthopaedics), prompting revision THA. To the best of our knowledge, this case represents the largest diameter fracture of this type of component reported to date.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
