Fracture Types and Locations by Age Group:
Children (0-12 years):
1. Greenstick Fractures:
• Location: Typically in the body or angle of the mandible.
• Reason: The elastic nature of children’s bones often results in incomplete fractures where the bone bends but does not break completely.
2. Condyle Fractures:
• Location: Mandibular condyle.
• Reason: Active growth centers and higher elasticity can lead to fractures at the condyle due to indirect forces during trauma.
Adolescents (13-18 years):
1. Condyle Fractures:
• Location: Mandibular condyle.
• Reason: Although less elastic than in childhood, the condyle remains a common fracture site due to its role in jaw biomechanics and remaining growth centers.
2. Body and Angle Fractures:
• Location: Body and angle of the mandible.
• Reason: Increased bone density and permanent dentition provide a stable structure, but these regions remain susceptible to fractures due to their anatomical positions.
Adults (19-64 years):
1. Angle Fractures:
• Location: Angle of the mandible.
• Reason: The angle is a common fracture site due to its anatomical structure and role in mastication.
2. Body Fractures:
• Location: The body of the mandible.
• Reason: Dense bone and strong cortical layer, yet the body remains vulnerable during significant trauma.
Older Adults (65+ years):
1. Condyle Fractures:
• Location: Mandibular condyle.
• Reason: Reduced bone quality and altered biomechanics due to aging increase the incidence of condyle fractures.
2. Angle and Body Fractures:
• Location: The angle and body of the mandible.
• Reason: Thinner cortical bone, alveolar ridge resorption, and less support from surrounding tissues make these areas more prone to fractures.
3. Symphysis and Parasymphysis Fractures:
• Location: Midline and near-midline areas.
• Reason: Although less common, these fractures can occur due to direct trauma, with the overall weakening of the mandibular structure making these regions more susceptible.
