All are true of pond’s fracture, except: CMC (Vellore) 13
**Core Concept**
Pond's fracture, also known as a greenstick fracture, is a type of non-displaced, incomplete fracture that typically occurs in the long bones of children, particularly the radius and ulna. However, in the context of this question, it is being used to describe a specific type of skull fracture.
**Why the Correct Answer is Right**
Pond's fracture typically refers to a non-displaced, linear fracture of the skull, often seen in infants due to the flexible nature of their skulls. This type of fracture occurs due to the shearing force exerted on the skull, causing a hairline crack in the bone. It is characterized by the absence of significant displacement or depression of the bone fragments. Since pond's fracture does not typically involve depression of the bone, option C describing a depressed fracture of the skull is incorrect.
**Why Each Wrong Option is Incorrect**
**Option A:** This statement is true as pond's fracture does not typically result in brain damage due to its non-displaced nature.
**Option B:** This statement is true as pond's fracture is commonly seen in infants due to the flexibility of their skulls.
**Option D:** This statement is true as pond's fracture does not typically involve shearing of the dura, which is a more severe injury.
**Clinical Pearl / High-Yield Fact**
It is essential to note that the term "pond's fracture" is sometimes misused to describe any non-displaced fracture, including those not involving the skull. To avoid confusion, it is crucial to specify the location and characteristics of the fracture when using this term.
**Correct Answer:**
✓ Correct Answer: C. Depressed fracture of the skull
