Maisonneuve fracture

A Maisonneuve fracture (named after Jules Germain François Maisonneuve, 1809-1897, French surgeon ) is a high, of nearby of the knee joint fracture of the fibula ( fibular fracture ) with a rupture of the fibrous membrane between the shinbone ( tibia) and fibula ( fibula ), called the interosseous membrane. The Maisonneuve fracture is one of the ankle fractures of type Weber C fracture. According to the band connection between the tibia and fibula is at the level of the ankle joint, called the syndesmosis, torn. This leads to instability and deformity of the ankle, resulting in increased in the course of " wear" of the joint.

Often the Maisonneuve fracture is associated with a medial malleolus fracture. Therefore, the ankle should be X-rayed together with the entire fibula.

Cause

Usually a Pronationstrauma of the ankle is the cause.

Therapy

A surgical treatment is indicated. The operation aims to achieve the correct position of the fibula in a corresponding cavity of the tibia ( the so-called incision ) to produce the best possible position of the two bones to each other at the ankle and therefore the congruency within the joint. After reduction tibia and fibula are held by one or two screws at a constant distance, in order to allow healing of the tape connecting between the two bones. These screws are called screws. Screws must be removed, as they break down at the beginning of the full load of the leg and then not completely remove are. The distance is generally carried out at six weeks.
