**Question:** Management of displaced non comminuted intercondylar humerus fracture is -

**Core Concept:** Intercondylar humerus fractures are a type of humerus fracture that occurs between the medial and lateral condyles of the humerus. They can be either comminuted or non-comminuted. Displaced fractures refer to the fracture fragment displacing more than 1 cm or more than 15 degrees from its normal anatomic position.

**Correct Answer: D.**

**Why the Correct Answer is Right:**

The correct answer is "D." Open reduction and internal fixation (ORIF) with plate and screws is the preferred management for displaced non-comminuted intercondylar humerus fractures. This technique allows for stable fixation of the fracture fragments, enabling early mobilization and avoiding complications like malunion, nonunion, and infection.

**Why Each Wrong Option is Incorrect:**

A. Closed reduction and percutaneous pinning (CRPP) is not an ideal management option for displaced non-comminuted intercondylar humerus fractures. The risk of neurovascular injury and infection is high, especially in cases of open injury or with significant comminution.

B. Amputation is not a suitable management option for intercondylar fractures. It is reserved for patients with extensive soft tissue damage, vascular compromise, or neurological injury where no viable salvage is possible.

C. Plaster immobilization is not recommended for displaced non-comminuted intercondylar humerus fractures. It results in poor fracture healing, loss of elbow and shoulder mobility, and an increased risk of infection.

**Clinical Pearl:**

In the management of displaced non-comminuted intercondylar humerus fractures, understanding the principles of fracture fixation is crucial. Stable fixation, early mobilization, and minimizing complications are essential for optimal patient outcomes.

**Why ORIF with plate and screws is the preferred method:**

1. ORIF with plate and screws provides stable fixation and allows for early mobilization of the affected limb, which is essential for fracture healing and preventing complications like malunion or nonunion.
2. The plate and screws provide rigid support to the fracture fragments and allow for early rehabilitation, reducing the risk of infection, malunion, and nonunion.
3. ORIF with plate and screws is also suitable for both intra-articular and extra-articular fractures.

**Why Plate and Screws are Superior to Other Options:**

1. Plate and screws provide a stable fixation and allow for early mobilization of the affected limb, which is essential for fracture healing and preventing complications like malunion or nonunion.
2. The plate and screws provide rigid support to the fracture fragments and allow for early rehabilitation, reducing the risk of infection, malunion, and nonunion.
3. Plate and screws are suitable for both intra-articular and extra-articular fractures, ensuring optimal management of the fracture type.

**Why Other Options are Inappropriate:**

1. Closed reduction and cast immobilization: This method results in poor fracture healing, loss of joint mobility, and increases the
