What is the most common cause of midline fractures?

The most common cause of midline fractures is impact, which typically results from trauma or injuries in activities such as sports, falls, or accidents. These fractures occur along the midline of the face and can involve the nasal bones, mandible, or other structures. The nature of impact forces—such as those from blunt force—can lead to significant stress on facial bones, making them more susceptible to fractures.

While fatigue and genetic predisposition can contribute to bone health and overall fracture risk, they are not direct causes of midline fractures in the same context as impact. Fatigue fractures generally occur in situations of repetitive stress over time rather than acute trauma, and genetic predisposition usually pertains to conditions affecting bone density or structure rather than specific injury scenarios. Defective dental work may lead to other complications or discomfort, but it is not a common cause of midline fractures themselves. Thus, impact remains the primary catalyst for such injuries.
