Abstract
A cadaver arterial injection study was performed to analyse the vascular supply to
the femur and to study the effects of two surgical plating techniques on femoral vascularity.
A 16-hole LC-DCP was applied on the intact femora of five fresh human cadavers. On
one side, the plate was inserted using a conventional lateral plate osteosynthesis
(CLPO) technique with elevation of the vastus lateralis muscle to expose the shaft.
On the contralateral side, the plate was inserted percutaneously beneath the muscle
using a minimally invasive plate osteosynthesis (MIPO) technique. After plating, blue
silicone dye was injected through the common femoral artery. Cadaveric dissection
was then performed to identify the femoral perforating arteries (PAs) and the nutrient
artery (NA) of the femur. The pattern of periosteal filling and medullary perfusion
of the injected dye was analysed and the topography of the PAs and NA was determined.
CLPO placed the PAs and NA of the femur at risk. MIPO maintained the integrity of
the PAs and NA and was associated with superior periosteal and medullary perfusion.
The results of this study indicate that MIPO is superior to the CLPO in maintaining
arterial femoral vascularity and perfusion.
