Complications of supracondylar fracture of humerus are all except –
**Core Concept**
Supracondylar fractures of the humerus are a common type of elbow fracture in children, typically occurring in the distal end of the humerus just above the condyles. The complications of this fracture are multifaceted and can involve various systems, including the vascular, nervous, and musculoskeletal systems.
**Why the Correct Answer is Right**
The most common complications of supracondylar fractures include:
* **Nerve injuries**: The median and radial nerves are at risk due to their proximity to the fracture site. The median nerve is particularly vulnerable to injury, which can result in numbness, tingling, and weakness in the hand.
* **Vascular injuries**: The brachial artery is at risk of injury, which can lead to impaired blood flow to the forearm and hand, resulting in ischemia or even compartment syndrome.
* **Malunion**: Incorrect reduction or poor immobilization can result in malunion, leading to cubitus varus or valgus deformity, which can cause functional impairment and cosmetic concerns.
* **Nonunion**: Inadequate immobilization or poor fracture healing can result in nonunion, requiring surgical intervention to achieve healing.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because while myositis ossificans can occur after a supracondylar fracture, it is not a direct complication of the fracture itself. Myositis ossificans is a secondary complication that can occur due to muscle injury or trauma.
**Option B:** This option is incorrect because while compartment syndrome is a potential complication of supracondylar fractures, it is not a direct complication. Compartment syndrome is a condition that can occur due to increased pressure within the muscle compartments, which can be caused by vascular compromise or other factors.
**Option C:** This option is incorrect because while infection is a potential complication of any fracture, it is not a direct complication of supracondylar fractures. Infection can occur due to various factors, including poor wound care, open fractures, or immunocompromised states.
**Clinical Pearl / High-Yield Fact**
A key consideration in the management of supracondylar fractures is the risk of nerve and vascular injury. A thorough neurovascular examination is essential to assess for any deficits or injuries. Early recognition and treatment of these complications can significantly improve outcomes.
