What describes a left sided condylar subluxation?

• A. Excessive translation of the condyle
• B. Inability to open the mouth
• C. Reduced clicking sounds during opening
• D. Minimal jaw deviation to either side

Answer: (A)

A left-sided condylar subluxation is characterized by excessive translation of the condyle, which means that the mandibular condyle moves beyond its normal range of motion relative to the temporal bone, particularly during jaw movement. This can occur when there’s a disruption in the normal mechanics of the temporomandibular joint (TMJ). As a result of this excessive movement, the condyle may not articulate correctly, leading to instability and potentially pain or dysfunction in the jaw.

Understanding the mechanics of the TMJ is crucial, as the condyles need to move in coordination during mouth opening and closing. When subluxation occurs, it disrupts this balance, which is why excessive translation is a defining feature. Other symptoms, such as clicking or jaw deviation, may arise, but they represent secondary effects rather than the primary definition of subluxation itself. Thus, identifying excessive translation directly links to the pathophysiology of a left-sided condylar subluxation.
