Summary
Acromioclavicular (AC) joint dislocation most commonly affects males aged 20-39, often due to sports injuries. This study analyzed AC joint dislocation epidemiology in an urban population.
Area of Science:
- Orthopedics
- Epidemiology
- Traumatology
Background:
- Acromioclavicular (AC) joint dislocation is a frequent shoulder injury.
- Limited data exists on the epidemiological characteristics of AC joint dislocations.
- Understanding these patterns is crucial for public health and clinical management.
Purpose of the Study:
- To investigate the epidemiology of isolated AC joint dislocations.
- To analyze demographic factors and injury mechanisms in an urban setting.
- To identify risk factors associated with AC joint injuries.
Main Methods:
- Retrospective analysis of a 5-year database of AC dislocation patients.
- Data collection included patient demographics, affected side, and injury mechanism.
- Radiographic review and classification using Rockwood's criteria.
Main Results:
- 108 patients diagnosed with AC dislocation (mean age 37.5 years).
- High incidence in males (8.5:1 ratio) and individuals aged 20-39 (50.5%).
- Sports injuries were the most common cause, with Rockwood type III being the most frequent dislocation.
Conclusions:
- Young males (20-39 years) are at higher risk for AC joint dislocation.
- Demographic factors significantly influence the occurrence of AC joint injuries.
- Findings provide essential epidemiological insights for prevention and treatment strategies.
