Is the GANNET a minimal invasive implant?
Increasing volume of the implant in the femoral head will compromise the (re) vascularisation of the head of femur and increase the incidence of avascular necrosis.
The volume of the DHS in the femoral head is 1975 mm3, while the volume of the DLBP is reduced to 920 mm3. Compared to the DHS, the cross section of the DLBP is reduced from 133 to 31 mm2. Also there exists a marked difference in the diameter of the pre-drilling in the femoral head; this is 9mm for the DHS and 5 mm for the DLBP. Because of the minimal cross section and volume of the implant in the femoral head, the DLBP is minimal invasive where it should be minimal invasive: that is the femoral head.
