Pott's fracture

From Wikipedia, the free encyclopedia

Pott's fracture, also known as Pott’s syndrome I and Dupuytren fracture, is an archaic term loosely applied to a variety of bimalleolar ankle fractures.^[1] The injury is caused by a combined abduction external rotation from an eversion force. This action pulls on the extremely strong medial ligament, often tearing off the medial malleolus. The talus then moves laterally, shearing off the lateral malleolus or, more commonly, breaking the fibula superior to the tibiofibular syndesmosis. If the tibia is carried anteriorly, the posterior margin of the distal end of the tibia is also sheared off by the talus. ^[2]

The bimalleolar fractures are less likely to be arthritic than trimalleolar fractures.^[3]

[edit] History

English physician Percivall Pott experienced this injury in 1765 and described his clinical findings in a paper published in 1769. ^[4][5]

The term "Dupuytren fracture" refers to the same mechanism,^[6] and it is named for Guillaume Dupuytren.^[7]
