These frequent fractures are usually best treated with lag screws. A minimum
of two screws must be used which necessitates that the fracture length is at
least twice the diameter of the phalangeal bone. In case of a shorter fracture
line, a single lag screw and a protection plate must be used.
A good rule is the following:
The fracture line (B) should be at least twice the length of the diameter of
the phalangeal diaphysis (A), i.e. B >= 2A.
