In human anatomy, the ankle joint is formed where the foot and the leg meet. The ankle, or talocrural joint, is a synovial hinge joint that connects the distal ends of the tibia and fibula in the lower limb with the proximal end of the talus bone in the foot. The articulation between the tibia and the talus bears more weight than between the smaller fibula and the talus. The term ankle is used to describe structures in the region of the ankle joint proper
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Bosworth fracture is a rare fracture of the distal fibula with an associated fixed posterior dislocation of the proximal fibular fragment which becomes trapped behind the posterior tibial tubercle. The injury is caused by severe external rotation of the ankle. The ankle remains externally rotated after the injury, making interpretation of X-rays difficult which can lead to misdiagnosis and incorrect treatment. The injury is most commonly treated by open reduction internal fixation as closed reduction is made difficult by the entrapment of the fibula behind the tibia.The entrapment of an intact fibula behind the tibia was described by Ashhurst and Bromer in 1922, who attributed the description of the mechanism of injury to Huguier's 1848 publication. The injury involving fibular fracture with posterior dislocation was described by David M. Bosworth in 1947.
Correctly choosing and executing the exposure needed for a given procedure is one of the orthopedic surgeon's most important tasks, and one that residents work hard to master. This covers all areas of orthopedic surgery, presenting exposures for hand & wrist, forearm, elbow, humerus, shoulder, pelvis, hip & acetabulum, femur, knee, tibia & fibula, foot & ankle, & spine.
