The radius or radial bone is one of the two large bones of the forearm, the other being the ulna.It extends from the lateral side of the elbow to the thumb side of the wrist and runs parallel to the ulna. The radius is shorter and smaller than the ulna. It is a long bone, prism-shaped and slightly curved longitudinally.. The radius is part of two joints: the elbow and the wrist.


Define apex. apex synonyms, apex pronunciation, apex translation, English dictionary definition of apex. n. pl. a·pex·es or a·pi·ces 1. a. The highest point of a structure, object, or geometric figure: the apex of a hill; the apex of a triangle. b.


Fractures of distal radius account for up to 20% of all fractures treated in emergency department. Initial assessment includes a history of mechanism of injury, associated injury and appropriate radiological evaluation. Treatment options include conservative management, internal fixation with pins ...


Regardless of what’s called on the print, this setup will produce an inside bend radius in the part much greater than that of the punch nose. In this case, the minimum producible inside bend radius is 63 percent of that 0.250-in. material thickness, or 0.1575 in. As another example, say you’re working with 0.125-in.-thick material.


- Distal Radius Fractures - Pediatric HPI - 10 year old girl fall on ground 3 weeks ago. She was treated with closed reduction and long arm case in full pronation. She is now 3 weeks out and presents with the radiographs shown. How would you treat this fracture now that it is 3 weeks out from the fracture.


The apex of a curve is its highest point. Geometric use of the term "apex" generally refers to solids or to shapes with corners such as triangles. In autoracing and other motor sports, the apex is the point on the track that is closest to the inside of a curve.


There are two different types of apex, the geometrical apex and the racing apex. The geometric apex of a constant radius corner is the central point on the inside and this can also be the racing apex, depending on the context. This can be confusing and is determined by your cornering strategy.


OSSB = [Tangent (Degree of bend angle / 2)] × (Inside bend radius + Material thickness) The outside setback is a dimensional value that begins at the tangent of the radius and the flat of the leg, measuring to the apex of the bend (see Figure 2). At 90 degrees, it does not matter if you use the included or complementary angle; you still end up ...


re: dimensioning to an apex ? CHRIS HOLSKE Oct 9, 2009 8:44 AM ( in response to Greg Hynd ) Greg, I did check that and now when I select the outside radius in each corner for dimensioning it brings the line to the tangent of the rad.


A Colles' fracture is a type of fracture of the distal forearm in which the broken end of the radius is bent backwards. Symptoms may include pain, swelling, deformity, and bruising. Complications may include damage to the median nerve.. It typically occurs as a result of a fall on an outstretched hand. Risk factors include osteoporosis. The diagnosis may be confirmed with X-rays.
