Summary
Road traffic accidents are the leading cause of mandibular condylar fractures, particularly in young males. Use of protective devices like helmets and seatbelts is crucial for prevention.
Area of Science:
- Oral and Maxillofacial Surgery
- Trauma Surgery
- Epidemiology
Background:
- Condylar fractures of the mandible are common facial injuries.
- Understanding their epidemiologic characteristics is vital for prevention and treatment strategies.
Purpose of the Study:
- To retrospectively analyze the prevalence, causes, types, and treatment of mandibular condylar fractures.
- To identify demographic and etiological factors associated with these fractures.
Main Methods:
- Retrospective analysis of 317 condylar fractures from 1999-2007.
- Data included demographics, etiology, fracture type, treatment, and associated injuries.
- Statistical analysis using chi-squared, Fisher's exact, t-tests, and Kruskal-Wallis test.
Main Results:
- A total of 317 fractures (209 unilateral, 54 bilateral) were analyzed, with a male predominance (3.05:1) and mean age of 28.4 years.
- Road traffic accidents were the primary cause (57.8%).
- Protective device usage and associated symphysis fractures showed significant correlations with condylar fractures.
Conclusions:
- Young adults are most affected, with road traffic accidents being the main cause.
- Mandatory use of safety helmets and seatbelts, alongside road safety education, can reduce facial fractures.
- Displaced subcondylar fractures were significantly associated with surgical intervention.

01:27Fractures: Bone Repair
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

01:16Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
