Cleaning the fracture site

Remove any small, loose fragments which may prevent anatomic reduction and free the periosteum from the bone edges.

It is important to visualize and inspect the joint, searching for bone and cartilage fragments detached from the medial malleolus or from the talus, and any impaction of the articular surface at the margin of the fracture. If the articular surface has been impacted, this must carefully disimpacted before the medial fragment is reduced.

Anatomical reduction

Reduce the fracture anatomically with the help of small pointed reduction forceps. Take care with the soft tissues.

Depending on fracture configuration and size of the fragment you may need to use large pointed reduction forceps through a lateral stab incision.

Do not strip the periosteum more than necessary.


In the presence of an impacted medial corner fragment, gently open the main vertical fracture plane by retraction of the medial malleolus medially (opening the book). The impacted “corner” fragment, usually identifiable by its articular cartilage, after irrigation if necessary, can then be seen.

Disimpact and carefully tease back the fragment into its anatomical position.

Then close the book by careful reduction of the medial malleolus.

Preliminary fixation

Insert a 1.6 mm K-wire as perpendicularly as possible to the fracture plane, about 1 cm proximal to the level of the horizontal tibiotalar joint line.

As decided in preoperative planning, this K-wire should be placed posteriorly in order not to interfere with the planned position of the plate.

Check the reduction under image intensification.
