Answer:  No


  • Diagnosis: is a comminuted, periprosthetic distal left femur fracture
  • Will not require revision if the implant is not loosened, there is sufficient bone for osteosynthesis, and he is not osteopenic
  • Periprosthetic fractures require consultation with orthopedics, admission for evaluation and likely surgery.
  • May need stabilization with intramedullary nail or locking plate prior to definitive management
