Some surgeons prefer to insert, in addition, a K-wire (but it can also be a second screw) to gain more stability of the fragment, especially to prevent rotation in the epiphyseal area.
Situations when a second implant might be selected are:
- Small additional fragments in the metaphyseal zone
- Very large metaphyseal fragment
- Older and bigger children
- Surgeon's personal preference
- Mobility of fracture line at the joint surface
