Abstract
The purpose of this study was to evaluate the osteosynthesis of proximal humeral fractures with a Polarus nail. Twenty-five patients with 2- and 3-part proximal humeral fractures were underwent osteosynthesis using Polarus nails.7 were males and 18 were females and the average age was 68 years old. The average follow-up period was 11 months. The results were evaluated based on the JOA shoulder score. The radiograph of the shoulder with maximum abduction was taken and the angle between the humeral shaft and glenoid (G-H angle)and the angle between the humeral shaft and vertical line to the floor (A angle) were measured. The ratio of the G-H angle to the A angle was calculated. All fractures were healed. The average postoperative JOA score was 84 points. The mean JOA pain score was 28 points and the mean JOA elevation score was 11 points. The mean abduction was 119 degrees. The mean G-H angle was 80 degrees. The mean A angle was 129 degrees. The ratio of G-H angle to A angle was 67%. Polarus nails for proximal humeral fracture lead to good results after an operation.
