RESUMO
Proximal humerus fracture is one of the common shoulder fractures. With the increase in incidence, the proportion of surgical intervention is increasing. This paper explores the traditional and new treatment methods for proximal humerus fracture. Locking plate technology is the most commonly used method in the clinic, but its complication rate of intra-articular screw penetration and reoperation is too high.Fibular strut allografts can provide adequate support, but it is a significant trauma surgery and has a high incidence of potential disruption to necessary vascular.Arthroplasty is one of the treatments for complex proximal humerus fractures, but it has a long learning curve and high cost.In recent years, the proximal humerus cage's intervention model has emerged, which has the inherent advantagesof a three dimensional structure, which can provide adequate load bearing support for the humeral head and provide flexible screw placement Angle. The cage offers a new technical option to reduce postoperative complications and improve patients' rehabilitation safety. A comprehensive grasp of the treatments of proximal humerus fracture and rational choice of intervention measures will benefit patients.
