Abstract
ABSTRACTS: Translational Study Introduction: The proximal humeral fracture accounts for 4-5% of all fractures1 and traffic accidents are often the main cause of this injury in Vietnam. Shoulder hemiarthroplasty is a suitable option in treating a complex proximal humeral fracture, especially in the elderly, and improves quality of life. This study describes clinical and radiographic characteristics of complex proximal humerus fractures and evaluates the results of shoulder hemiarthroplasty for this type of fracture at Viet Duc University Hospital Materials and methods: A retrospective study of 78 cases with complex proximal humeral fractures underwent shoulder hemiarthroplasty in Viet Duc University Hospital from January 2017 to December 2021. RESULTS: Traffic accidents (42 cases, 53.8%); daily-life accidents (34 cases, 43.6%), other causes were less common (2 cases, 2.6%). 74.4% of the patients had no pain, 17.4% mild pain, 7.7% moderate pain, and no patients suffered from severe pain that required regular narcotic analgesics. The mean postoperative Constant score was 67.45 ± 13.20. CONCLUSION: In Viet Nam, the most common cause of injury was a traffic accident, primarily occurring in young males with complex proximal humerus fractures, shoulder hemiarthroplasty for complex proximal humerus fractures improves postoperative pain and shoulder function.
