Research progress of hemi-shoulder replacement in treatment of proximal humeral fracture

Proximal humeral fractures most frequently occur to middle and o1d-age patients, and the major treatment is hemi-shoulder joint replacement. However, therapeutic effects and prognosis after shoulder joint replacement can be influenced by bony landmarks damage, the uncertainty of placement height and back rotation angle of prosthesis, greater and lesser tubercles not meeting the requirements of anatomical reduction and so on. Therefore, in order to treat the proximal humeral fractures and reduce the occurrence rate of postoperative complications, doctors need to be familiar with the anatomic relationships between shoulder joints, the mechanical mechanism and the special reconstruction techniques of the shoulder joint and make meticulous operation plans. This review was about the situations of treating the proximal humeral fractures through shoulder joint replacement in recent years. Key words: Shoulder fractures; Hemiarthroplasty; Therapeutics
