Hat-Trick: On a Case of Hip Replacement Complicated by Dislocation and Infection and Periprosthetic Fracture

Case Presentation: A 79-year-old man with several general medical comorbidities referred to our orthopaedic Unit with dislocation, infection and periprosthetic fracture of a long-stem hip hemiarthroplasty. Results: A one-stage revision was performed using a dual mobility cup and a standard modular-neck stem, both fixed with antibiotic-loaded cement. Conclusion: Hip replacement is a common treatment for femoral neck fractures in the elderly population with a significant improvement in the quality of life of patients. Local complications can lead to poor outcomes. The simultaneous presence of dislocation, infection and periprosthetic fracture is a challenge of treatment for the surgeon and the frailty of the patients get this scenario even worse. Every attempt must be driven toward a safe and time-preserving “single-shot” procedure
