The treatment of an ankle fracture and the time taken to heal will depend on many factors, including: the type of ankle fracture, where the bone is broken, how many of the bones are broken; the condition of your skin over the fracture. A common way of classifying fractures is the Weber System. This system is based on the relationship between the two large bones â the fibia and tibula. Just above the ankle joint, these two bones are joined by a strong band of tissue called the 'syndesmosis ...
The process by which the oceanic crust is pulled under the continental crust is called subduction and the zone at which this occurs at the plate boundaries is called the subduction zone. At the subduction zone where the oceanic crust sinks beneath the continental crust a deep oceanic trench or valley is created.These can be many of thousands of kilometres long and 8 to 10 kilometres deep making them the deepest part of the ocean floor.t the subduction zone where the oceanic crust sinks beneath the continental crust a deep oceanic trench or valley is created.

Convergent plate boundaries. 1  Oceanic-continental The denser oceanic slab slides under the continental slab. The contact region is called a subduction zone, and a trench is formed there. 2  Oceanic-oceanic One of the oceanic plates slides underneath the other. The region of contact is again called a subduction zone.
