Green extra aicular ahrodesis done for –
**Core Concept**
A greenstick extra-articular arthrodesis is a surgical procedure used to fuse two or more bones together outside of a joint, typically used in cases where a traditional arthrodesis (joint fusion) is not feasible or has failed. This procedure is often performed in the context of deformity correction, pain management, or as a salvage option for failed arthroplasty.
**Why the Correct Answer is Right**
The correct answer is **C**. Greenstick extra-articular arthrodesis is typically performed for patients with severe deformities, such as those resulting from cerebral palsy, muscular dystrophy, or other conditions that have led to joint instability or degeneration. The procedure involves the use of a bone graft to fuse the bones together, often in conjunction with internal fixation devices such as rods or plates. This approach allows for the correction of deformity and the relief of pain, while minimizing the risk of further joint damage.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not provide a clear indication for greenstick extra-articular arthrodesis.
**Option B:** This option is incorrect as it is a different surgical procedure altogether, not related to greenstick extra-articular arthrodesis.
**Clinical Pearl / High-Yield Fact**
It's essential for surgeons to carefully evaluate patients with severe deformities or joint instability to determine the best course of treatment, as greenstick extra-articular arthrodesis may be a viable option in certain cases. However, this procedure should be approached with caution, as it carries risks of infection, nerve damage, and nonunion.
**Correct Answer:** C.
