Presentation
Fall from a height of 1.5 meters. Severe ankle pain and deformity and was unable to bear weight.
Patient Data
There is lateral and posterior dislocation of the talus, compatible with disruption of the medial tibiofibular joint space / syndesmosis and likely deltoid ligament tear.
Spiral fracture of the proximal fibular shaft, which when combined with the talar dislocation, is compatible with a Maisonneuve fracture-dislocation.
Case Discussion
Maisonneuve fracture-dislocation is a combination of distal tibiofibular syndesmosis disruption with possible deltoid ligament tear (unstable ankle injury that might or might not be associated with medial malleolus fracture) with proximal fibular fracture. This case shows why imaging of the entire fibula is a must if widening of the medial tibiotalar joint space is present on an ankle radiograph. Maisonneuve fracture is a variant of Weber type C fracture that requires knee or full-length tibia-fibula radiographs.
