Avulsion from the tibia (Tillaux-Chaput)
Anatomically reduce the fragment with a small dentist hook and preliminarily fix it with a 1.0 mm K-wire.
Drill a hole with a 2.5 mm drill bit and protection sleeve as perpendicular as possible to the fracture line without drilling the far cortex.
Measure the depth. Tap with the 4.0 mm tap and protection sleeve. Insert the 4.0 mm cancellous screw with a washer.
If the fragment is too small for 4.0 mm screw fixation, use a 2.0 mm or a 2.7 mm cortical screw or suture the fragment to the periosteum of the anterior tibia.
