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.
1 The price of retaining wall construction can depend on several factors. 2  The main difference in the price can be due to the type of material that will be used to build the wall. 3  On average, a professional contractor is going to charge anywhere from $17 to $35 per square face foot. A retaining wall that uses a material such as wood rather than brick can cost anywhere from $19 to $30 per square face foot for a professional laborer to come in. 2  Higher quality stone can cost upwards of $40 per square face foot.
