Preferred treatment of cubitus varus is –
**Core Concept**
Cubitus varus, also known as gunstock deformity, is a condition characterized by a decrease in the carrying angle of the elbow, resulting from malunion of a supracondylar fracture of the humerus. The preferred treatment aims to correct the deformity, restore the normal carrying angle, and improve the functional outcome.
**Why the Correct Answer is Right**
The preferred treatment for cubitus varus involves surgical correction, specifically a lateral closing wedge osteotomy. This procedure involves cutting and repositioning the bone to correct the deformity. The osteotomy is typically performed in the lateral aspect of the humerus, and the wedge is closed to restore the normal carrying angle. This approach allows for accurate correction of the deformity and minimizes the risk of complications.
**Why Each Wrong Option is Incorrect**
* **Option A:** Closed reduction and casting may be used to treat some cases of cubitus varus, but it is not the preferred treatment for significant deformities.
* **Option B:** Open reduction and internal fixation may be necessary in some cases, but it is not the primary treatment for cubitus varus.
* **Option C:** Physical therapy alone is not sufficient to correct the deformity and restore the normal carrying angle.
**Clinical Pearl / High-Yield Fact**
It is essential to diagnose and treat cubitus varus early to prevent long-term complications, such as limited elbow flexion, decreased carrying angle, and potential neurological deficits.
**Correct Answer: C. Physical therapy alone is not sufficient to correct the deformity and restore the normal carrying angle.**
