The Rorabeck and Taylor classification system is the widely utilized standard for guiding the surgical management of periprosthetic fractures of the distal femur that occur superior to a total knee arthroplasty. How is a Type II Rorabeck fracture strictly defined?
A
A totally non-displaced fracture where the femoral component remains perfectly stable and solidly fixed to the bone.
B
A highly comminuted fracture located strictly at the proximal femoral diaphysis, far removed from the actual knee component.
C
A fracture pattern where the femoral component is grossly loose and mobile, regardless of the degree of fracture displacement.
D
A fracture that is significantly displaced and angulated, but crucially, the femoral component itself remains rigidly fixed and osseointegrated to the distal bone fragment.
