After falling from a height, a child lands on his fully outstretched hands. On examination there is pain and swelling over his right elbow. Give your probable diagnosis –
**Core Concept**
The question tests the understanding of common elbow injuries in children, particularly those resulting from a fall onto an outstretched hand. This mechanism of injury can lead to various elbow fractures or dislocations due to the transmission of force up the forearm.
**Why the Correct Answer is Right**
Given the mechanism of injury and the symptoms described, the most likely diagnosis is a supracondylar fracture of the humerus. This type of fracture is common in children and occurs just above the elbow joint. It happens when a child falls onto an outstretched hand, causing the humerus to break just above the condyles.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific details of option A, it's challenging to provide a precise reason for its incorrectness. However, if it suggested a diagnosis unrelated to the common consequences of falling onto an outstretched hand, it would be incorrect due to the mismatch with the clinical presentation.
**Option B:** Similarly, without specifics, if option B proposed a condition not typically associated with this mechanism of injury, it would be incorrect.
**Option C:** If option C suggested a radial head fracture, while possible, it's less common in this scenario compared to a supracondylar fracture.
**Option D:** If option D proposed an injury unrelated to the elbow, given the pain and swelling over the elbow, it would be incorrect.
**Clinical Pearl / High-Yield Fact**
Supracondylar fractures of the humerus are notorious for potential neurovascular complications, including brachial artery injury and nerve damage. Prompt recognition and appropriate management are crucial to avoid long-term sequelae.
**Correct Answer:** D. Supracondylar fracture of the humerus.
