Final answer:
In the Weber classification scheme, type B describes a spiral fracture of the fibula extending from the joint line in a proximal posterior direction up the fibular shaft.
Step-by-step explanation:
In the Weber classification scheme, type B describes a spiral fracture of the fibula extending from the joint line in a proximal posterior direction up the fibular shaft.
When the fibula is fractured in this manner, it usually occurs due to twisting forces applied to the leg. This type of fracture is commonly seen in sports-related injuries or accidents.
The Weber classification scheme is used to categorize fractures based on their severity and the location of the injury in relation to the ankle joint.
