humerus, regardless of the level or number of fracture lines, in which no segment is displaced more than 1cm or angulated more than 45Â°. Two-part fractures The two-part fracture includes those proximal humeral fractures with a single displacement at the anatomic neck, surgical neck, lesser tuberosity, or greater tuberosity. The fracture is named by the structure that is displaced (Two-part surgical neck fracture). Three-part fractures The three-part fracture includes all proximal humeral fractures with a displaced surgical neck and either a greater or lesser tuberosity displacement fracture. Four-part fractures Four-part fractures are proximal humeral fractures with three displaced, fractured segments including both tuberosities and typically the surgical neck.
The cost of building and maintaining a double set of steel fences along 700 miles of the U.S.-Mexico border could be five to 25 times greater than congressional leaders forecast last year, or as much as $49 billion over the expected 25-year life span of the fence, according to the nonpartisan Congressional Research Service.
If Donald Trump were to build a wall along the United States' southern border, it would cost billions. The U.S. border with Mexico is roughly 2,000 miles long and underlines four states from California to Texas.he actual cost for the rest of the border wall (roughly 1,300 miles) could be as high as $16 million per mile, with a total price tag of $15 billion to $25 billion.
