    A 28-year-old man with a history of osteosarcoma experienced a displaced femoral neck fracture after a fall, complicating his previous knee tumor prosthesis.

    The reconstruction utilized a customized monoblock stem with a socket-type prosthesis-to-prosthesis coupling to preserve the stable distal component.

  • 3

    Postoperative imaging confirmed satisfactory alignment, and limb-length discrepancy improved from 20 cm to 15 cm after the surgery.

  • 4

    The Harris Hip Score improved from 63 at 3 months to 81 at 6 months, indicating significant functional recovery.

  • 5

    This case highlights the feasibility of component-preserving reconstruction as an alternative to total femoral replacement in complex proximal femoral defects.
