Management of a periprostetic femoral fracture

This clinical case presents the management of a periprosthetic femoral fracture occurring shortly after hemiarthroplasty in a 68-year-old patient. Based on the initial clinical presentation and imaging findings, how would you approach fracture assessment in this situation?

Part one
Clinical presentation
  • 68 year-old female
  • Walks with a walker because of a hydrocephaly treated 20 years ago
  • Left bipolar hemiarthrosplasty implanted 2 weeks ago for a Garden 4 neck fracture
  • Fall while walking

Part two

What classification allows us to classify this fracture and what is its grade?

  • ✔️Vancouver classification grade B1

The French Society of Orthopedic Surgery and Traumatology (SoFCOT) recommended a specific Remaining Attachment Index (RAI) to asses residual fixation. Remaining Attachment Index < 2/3 in Vancouver B1 periprosthetic hip fracture is a risk factor for early implant loosening after isolated internal fixation

What could have been done to reduce the risk of this type of complication?

  • ✔️Cemented stem
  • ✔️Collared stem

How would you manage this condition? 

  • ✔️Femoral ORIF with a plate alone

Final strategy decision
  • In this case, we decided to perform a simple ORIF with a plate (Depuy Synthes) due to the Vancouver B1 type of fracture and Remaining Attachment Index >  2/3
  • A full weight bearing was allowed because of her condition.
  • At 6 weeks post-op she was able to walk with her walker again
