A graphically illustration of the three tibial volumens that are determined for CT evaluation of bone ingrowth into the Healicoil screws. a: Volumen of the tibial tunnel in the location of the Healicoil screw. b: Volume of the PEEK material of the Healicoil screw. c: Volumen of the new bone formation in the areas of screw voids. Bone ingrowth is determined as New bone volume C/Void volumen a – b
