The Maisonneuve fracture of the fibula.

Nine patients sustained a Maisonneuve fracture of the fibula (MFF), which is a proximal fibula fracture associated with an ankle fracture or deltoid ligament tear. Eight were treated with closed reduction and plaster casts. One was treated by open reduction and internal fixation. Reexamination was performed at an average of 25.7 months. This included subjective, objective, and functional evaluations, along with stress roentgenograms. Six patients had an excellent result, two a good result, and one a fair result. The MFF is often more stable than generally assumed. For injuries with only a partial syndesmotic disruption, nonoperative treatment is recommended.
