Vascular injury during childhood is common in fracture of –
**Core Concept**
Vascular injury during childhood can occur due to the fragile nature of blood vessels in pediatric patients, particularly in long bone fractures. This is often related to the open growth plates and the relatively small size of the blood vessels. The risk of vascular injury is higher in fractures that involve the metaphysis or the growth plate.
**Why the Correct Answer is Right**
The most common fracture associated with vascular injury in childhood is the supracondylar fracture of the humerus. This type of fracture occurs just above the elbow joint and involves the distal humerus. The risk of vascular injury is highest in type III supracondylar fractures, which are characterized by a posterior displacement of the distal fragment. The brachial artery, which runs through the arm and supplies blood to the forearm and hand, is at risk of injury in these fractures.
**Why Each Wrong Option is Incorrect**
* **Option A:** Femur fractures are less common in childhood and are not typically associated with vascular injury.
* **Option B:** Clavicle fractures are common in childhood but are rarely associated with vascular injury.
* **Option C:** Ribs are not typically associated with vascular injury in childhood.
**Clinical Pearl / High-Yield Fact**
Remember that the risk of vascular injury is highest in fractures that involve the metaphysis or growth plate, particularly in the distal humerus. This is a classic exam trap, and students should be able to recognize the association between supracondylar fractures and vascular injury.
**Correct Answer:** D. Supracondylar fracture of the humerus.
