OUTCOME OF SHOULDER HEMIARTHROPLASTY FOR COMPLEX PROXIMAL HUMERAL FRACTURE IN VIETDUC UNIVERSITY HOSPITAL.

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.

Effecacy of methotrexate in medical treatment for 100 patients with unruptured ectopic pregnancies at Women Hospital of hai Phong

A clinical trial was conducted from 6/2001 to 5/2004 at Women hospital of Hai Phong to look for efficacy of Methotrexate (MTX) in medical treatment of unruptured ectopic pregnancies. 100 patients admitted the hospital due to unruptured ectopic pregnancies with βhCG > 100mUl/ml- <10.000mUl/ml. Tubal diameter < 3cm were enrolled in study. Treatment consisted of 50mg/m2 skin of MTX injected intramusculary and all patients were followed up by utrasound and βhCG after 48 hours and then 7 days. Injection was repeated if βhCG declined less than 15% of the initial level or increased at the 7th day after the first dose. Maximum doses of MTX used were 3 courses. 71 out of 100 patients (71%) were treated with one dose of MTX, 27 with two courses (27%), and two patients with 3 courses. Success rate was 83%. Serious side effects of MTX were note, unless 20 patients had mild side effects. Pregnancy rate after treatment reached 42.8% with recurrent ectopic pregnancy rate was 4.8%.
