Summary
Proximal femoral replacement (PFR) with a locking plate effectively reconstructs massive femoral bone loss in elderly patients, preventing complications like loosening and fractures. This technique ensures robust fixation and allows early weight-bearing, leading to excellent long-term outcomes.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Complications following proximal femoral replacement (PFR), including stem loosening and periprosthetic fractures, are primary drivers for revision surgery.
- Massive proximal femoral bone loss, often classified as Paprosky type IV, presents significant challenges in revision arthroplasty.
