**Question:** Garden's classification is applicable to

A. Head injuries
B. Cardiovascular diseases
C. Neurological disorders
D. Orthopedic injuries

**Correct Answer:** D. Orthopedic injuries

**Core Concept:** Garden's classification is a system used to categorize and describe the severity of femoral neck fractures based on the degree of displacement and comminution.

**Why the Correct Answer is Right:** Garden's classification was developed by British surgeon Sir Archibald Garden and is widely used among orthopedic surgeons to guide treatment decisions for femoral neck fractures. The classification system is based on the degree of fracture displacement and comminution, which helps predict the risk of avascular necrosis, osteonecrosis, and subsequent osteoarthritis in patients.

**Why Each Wrong Option is Incorrect:**

A. Head injuries (A) refer to injuries affecting the brain or skull, not specifically femoral neck fractures. Garden's classification is not relevant to head injuries.
B. Cardiovascular diseases (B) involve conditions related to the heart and blood vessels, not fractures. Garden's classification does not apply to cardiovascular diseases.
C. Neurological disorders (C) are conditions affecting the nervous system, unrelated to fractures. Garden's classification is not relevant to neurological disorders.

**Clinical Pearl / High-Yield Fact:** Garden's classification is essential for clinicians managing femoral neck fractures, as it helps guide treatment decisions, including deciding whether to use conservative management (e.g., immobilization) or surgical intervention (e.g., hemiarthroplasty or total hip arthroplasty). Understanding the classification allows for appropriate patient management and outcomes optimization.
