|Groups||Implant picture||Material||Design/fixation principle|
|TomoFix sm (Group IV)||Titanium||Same fixation principle with the TomoFix std. Geometry adapted from the TomoFix std. to patient with small stature|
|ContourLock (Group V)||Titanium||Short spacer plate with large proximal part and angle stable multidirectional screws.|
The proximal screws are monocortical and fixed in the cancellous bone and the distal screws are bicortical.
|Activmotion (Group VI)||Titanium alloy||Internal fixator with eight monoaxial locking screws. The diaphyseal screws are bicortical while the epiphyseal are monocortical|
|FlexitSystem (Group VII)||Titanium alloy||T-shaped internal fixator, shorter than the TomoFix plates, with angle stable unidirectional screws. The proximal screws are monocortical and fixed in the cancellous bone and the distal screws are bicortical.|
