**Question:** Fracture of lateral condyle of humerus seen in age group of
A. Children
B. Adults
C. Elderly
D. Teenagers
**Correct Answer:** A. Children
**Core Concept:**
The lateral condyle of the humerus is a bony prominence on the lateral (outer) side of the humerus, the long bone in the upper arm. Fractures of the lateral condyle are predominantly seen in children due to their growth and increased bone fragility.
**Why the Correct Answer is Right:**
Fractures of the lateral condyle are most commonly seen in children, particularly during growth spurts. This is because children's bones are still growing, which increases their flexibility but also makes them more prone to fractures. Moreover, the growth plate (epiphysis) adjacent to the lateral condyle is more susceptible to injury in children compared to adults.
**Why Each Wrong Option is Incorrect:**
1. **Option B (Adults):** While fractures can occur in adults, they are less common than in children due to the stronger bones and mature growth plates.
2. **Option C (Elderly):** The elderly often have osteoporosis, a condition characterized by weak bones, which increases the likelihood of fractures. However, the focus of this question is on the age group most prone to lateral condyle fractures, not the overall fracture incidence in the elderly.
3. **Option D (Teenagers):** While teenagers are in the age group adjacent to children, fractures in this age group are less common than in children due to the reasons mentioned above (growing bones and immature growth plates).
**Why the Correct Answer is Right:**
Fractures of the lateral condyle are primarily seen in children due to their growing bones and immature growth plates, which make them more prone to fractures. The increased bone flexibility allows for greater trauma to cause fracture, while the immature growth plates increase the risk of complications and malunion (incomplete healing) if the fracture occurs. This type of fracture is less common in adults, teenagers, and the elderly due to factors such as stronger bones and mature growth plates.
**Why Each Wrong Option is Incorrect:**
1. **Option B (Adults):** While adults can experience fractures, they have stronger bones and less immature growth plates, making them less likely to have a lateral condyle fracture compared to children.
2. **Option C (Elderly):** Elderly individuals are more prone to fractures due to osteoporosis, which weakens bones. However, the focus of this question is on the age group most likely to have a lateral condyle fracture, not the overall fracture rate in the elderly.
3. **Option D (Teenagers):** Similar to adults, teenagers have stronger bones and less immature growth plates, making lateral condyle fractures less common in this age group compared to children.
**Clinical Pearl:**
In summary, lateral condyle fractures are more common in children due to their growing bones and immature growth plates, making them more susceptible to trauma-induced fractures. This principle applies to teenagers as well, as they are also
