The 'three bony point relationship' at the elbow has a lot of clinical significance. Which of the following statements is false (AIIMS Nov 2010)
|A||In posterior dislocation of elbow the triangle is reversed.|
|B||In a supracondylar fracture the relationship of the three body points is maintained.|
|C||The base of the triangle is broadened in inter condylar fracture of humerus.|
|D||The points are marked out with the elbow in extension.|
The points are marked out with the elbow in extension
a. The three bony points in question are the medial epicondyle, lateral epicondyle and the tip of the olecranon.
b. They form a triangle when the elbow is in 90o of flexion, with the line joining the medial epicondyle and the olecranon being the shortest. In extension the three points form a straight line.
