What is a supracondylar fracture?
Supracondylar humeral fracture - Supracondylar fractures are the most common type of upper arm injury in children. It is an injury to the humerus, or upper arm bone, at its narrowest point, just above the elbow. They are frequently caused by a fall on an outstretched elbow or a direct blow to the elbow such as the median and the radial nerve. The displaced fracture fragments may impinge and damage the contents of the cubital fossa such as the median and radial nerve. Direct damage or post-fracture swelling can cause interference to the blood supply of the forearm from the brachial artery. The resulting ischemia can cause Volkmann’s ischaemic contracture .

The cubital fossa is an area of transition between the anatomical arm and the forearm. It is located in a depression on the anterior surface of the elbow joint. It is also called the antecubital fossa because it lies anteriorly to the elbow (Latin cubitus) when in standard anatomical position. The cubital fossa is triangular, and thus has three borders along with an apex which is directed inferiorly. It also has a floor and roof, and it is traversed by structures which make up its contents.[1][2][3][4]
