Closed pinning not done in
**Core Concept**
Closed pinning is a surgical technique used to stabilize and align fractured bones, particularly in the case of dislocated joints or fractures that require precise reduction. This procedure involves the insertion of pins or wires to hold the bone fragments in place, allowing for proper healing and alignment.
**Why the Correct Answer is Right**
The correct answer is related to a specific type of fracture or condition where closed pinning is contraindicated. Closed pinning is generally avoided in cases of open fractures, where the skin is compromised and the risk of infection is high. The presence of an open wound increases the risk of introducing bacteria into the wound, leading to infection and potentially life-threatening complications.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because closed pinning is not typically contraindicated in cases of osteoporotic fractures. In fact, closed pinning may be used to stabilize and align osteoporotic fractures, particularly in the elderly population.
**Option B:** This option is incorrect because closed pinning is not typically contraindicated in cases of fractures with significant soft tissue damage. While soft tissue damage may require additional surgical attention, closed pinning can still be used to stabilize and align the fracture.
**Option C:** This option is incorrect because closed pinning is not typically contraindicated in cases of fractures with neurovascular compromise. In fact, closed pinning may be used to stabilize and align fractures that have compromised neurovascular structures, provided that the neurovascular bundle is carefully preserved.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that closed pinning is generally contraindicated in cases of open fractures, where the risk of infection is high. This is because the presence of an open wound increases the risk of introducing bacteria into the wound, leading to infection and potentially life-threatening complications.
**Correct Answer: D. Open fractures.
