Alternative: use K-wires in avulsed fragment

If the avulsed fragment is large enough, two 0.6 mm K-wires can be inserted to secure it to the main fragment of the middle phalanx. These K-wires can then be used to anchor the tension band wire on the avulsed fragment.
Check palmar protrusion of the K-wires under image intensification. Then retract the K-wires by about 2 mm, bend them through 180 degrees, cut them and impact them into the bone. The K-wires must engage the far cortex, but must not protrude into the flexor tendon tunnel, in order to avoid irritating the tendons.

The K-wires will prevent tilting of the fragment on tightening of the wire.
