**Supracondylar Fracture of Humerus: Key Concepts**

* **Core Concept:** Supracondylar fractures of the humerus are a type of elbow fracture that occurs just above the condyles of the humerus in children. These fractures are often associated with a specific set of clinical and radiographic findings.

**Why the Correct Answer is Right**

* Supracondylar fractures are typically seen in children due to the open growth plates and bone structure at this age. The fracture occurs when a child falls onto an outstretched hand, causing a force to be transmitted up the forearm and into the elbow. This can lead to a fracture just above the elbow joint.
* The most common type of supracondylar fracture is the extension type, which accounts for approximately 98% of cases. This type of fracture is characterized by a posterior displacement of the distal fragment.
* Other types of supracondylar fractures include flexion type and Monteggia equivalent fractures.

**Clinical Pearl / High-Yield Fact**

* The most common complication of supracondylar fractures is neurovascular injury, particularly to the brachial artery and median nerve. It is essential to carefully assess the neurovascular status of the affected limb in all cases of supracondylar fracture.
