Modified fixations for distal femur fractures following total knee arthroplasty: a biomechanical and clinical relevance study

Abstract

The spiral-blade supplement of retrograde intramedullary nail and locking plate/allograft modified constructs significantly stabilizes the unstable fractured gaps. The locking plate/allograft is recommended for the periprosthetic fractures with deficient bone stock and severe osteoporosis to improve alignment and healing potentials.
