In recent years, proximal humerus fractures have become one of the major fractures in orthopedics trauma. The purpose of this study was to investigate the Shoulder function of post operative(PO) proximal humerus fracture. 19 shoulders treated with intramedullary nail were prepared for this study. They were divided into 3 groups, which were defined as follows; Group1) 50-64 year-old, Group2) 65-74 year-old Group3) 75- year-old. Post operative and unaffected range of motion of the shoulder (flexion (Flex), external rotation (ER), and internal rotation (IR)) were investigated once a month until 6 months. Results of range of motion of the shoulder were as follows; Group 1 (PO; F147, ER52.5, IR4.7/ unaffected side; F163, ER56.7, IR6.0), Group 2 (PO; F133, ER54, IR3.6/ unaffected side; F149, ER54.2, IR4.6), Group3(PO; F120, ER48, IR4.0/ unaffected side ; F126, ER50.8, IR3.7). 75 years old or more people recovered to pre-operative function. However, 50-64 year-old people had limitations of range of motion, in particular flexion and internal rotation.
