## **Core Concept**
A syndesmosis is a type of fibrous joint, or synarthrosis, where bones are linked by ligaments, a syndesmosis allows for slight movement. This type of joint is characterized by the presence of ligaments that connect the bones, providing stability while permitting some degree of mobility.

## **Why the Correct Answer is Right**
The correct answer, **D. Inferior tibiofibular joint**, is an example of a syndesmosis joint. This joint is located between the distal ends of the tibia and fibula in the leg. The bones are connected by strong ligaments, which allow for minimal movement. This type of joint provides stability to the ankle and lower leg.

## **Why Each Wrong Option is Incorrect**
- **Option A:** The distal radioulnar joint is indeed a type of joint but specifying its type requires understanding it is a synovial pivot joint, not a syndesmosis.
- **Option B:** The interosseous membrane of the forearm is a fibrous structure that connects the radius and ulna, providing a syndesmosis-like function but is not classified as a joint itself.
- **Option C:** The intervertebral disc is an example of a symphysis, a type of cartilaginous joint, not a syndesmosis.

## **Clinical Pearl / High-Yield Fact**
A key clinical correlation for syndesmosis joints is their role in injuries, particularly in sports. A common injury is a syndesmosis ankle sprain, which can be challenging to diagnose and treat. Understanding the anatomy and function of syndesmosis joints is crucial for managing such injuries.

## **Correct Answer:** D. Inferior tibiofibular joint
