Dislocation is a disease caused by

Options

A. Biological agent
B. Mechanical agent
C. Physical agent
D. Chemical agent

Answer

**Step-by-Step Solution:**

1. **Understanding Dislocation**: Dislocation is defined as an abnormal separation of the joint or bones. It typically occurs when the bones in a joint are forced out of their normal positions.

2. **Identifying Common Sites**: The most common sites for dislocation include the shoulder, hip, patella (kneecap), ankle, and fingers. These areas are particularly vulnerable due to their range of motion and the stresses they endure.

3. **Causes of Dislocation**: Dislocations can occur due to various factors, including trauma, falls, or accidents. These events often involve a significant force that impacts the joint.

4. **Categorizing the Cause**: The question asks about the type of agent that causes dislocation. The options provided are:
- a. Biological agent
- b. Mechanical agent
- c. Physical agent
- d. Chemical agent

5. **Analyzing the Options**:
- **Biological agents** typically refer to pathogens like bacteria or viruses, which do not cause dislocation.
- **Mechanical agents** involve forces or impacts that can lead to physical injuries, including dislocations.
- **Physical agents** could refer to environmental factors but are not specific to the forces causing dislocation.
- **Chemical agents** involve substances that can cause damage at a molecular level, which is not applicable to dislocation.

6. **Conclusion**: Based on the analysis, the correct answer is **b. Mechanical agent**, as dislocations are primarily caused by physical forces acting on the joints.

**Final Answer**: Dislocation is a disease caused by **b. Mechanical agent**.
