The two primary choices for quadrilateral are either LON tibia + Precice femur, or x2 Precice.
Precice x2 can yield a maximum of 14cm (8 femur + 6 tibia).
LON tibia + Precice femur would still essentially offer a maximum of 14cm, as exceeding 6cm on the tibia with LON could lead to ballerina syndrome.
It is important to note that LON femur + Precice tibia is not a usual combination for quadrilateral. However, if pursued, a theoretical increase of 16cm could be achieved, given that LON can provide up to 2 extra cm on the femur compared to Precice (i.e., 10 femur + 6 tibia).
I have inquired about why LON femur + Precice tibia is uncommon. It seems this is related to the stability of LON tibia + the discomfort associated with LON femur procedures.
The facility I have consulted with mentioned that LON femur + Precice tibia can be performed for quadrilateral, though it is atypical.
The unconventional question is:
Would you opt for Precice x2, or the unique combination of LON femur + Precice tibia for quadrilateral.
Cost is not a concern. Additionally, I am indifferent to any additional discomfort or pain during the process. My primary apprehension regarding LON is the risk of infection. I ponder, “Is it justified to accept the heightened infection risk in exchange for potentially gaining another 2cm on the femur?”
Your assistance is valued,
