Abstract:

Objective　To investigate the clinical and anatomical factors including brachial plexus and posterior humeral circumflex artery in humeral head replacement of the proximal humerus fractures.　Methods 15 patients with displaced 4-part fractures of the proximal humerus were treated. The mean age was 63.5 years. The brachial plexus and posterior humeral circumflex artery were protected and the humeral head were replaced in all patients.　Results　All patients were followed. The mean follow-up period was 16.2 months. The average ConstantScores was 80.5 (range 61-89) in the last follow-up.　Conclusion　Humeral head replacement is an effective therapy for complex fractures of the proximal humerus. Meticulous surgical operation is essential to the prevention of complications and achievement of good results.
