Most proximal humeral fractures respond satisfactorily to conservative treatment. It is only the occasional displaced fracture or fracture-dislocation that demaads special treatment. The purpose of this study is to analysis the results of closed and open reduction of displaced proximal humeral fractures according to Neers classification. Fifty-two cases of these fractures, followed up more than five months, are presented. 1. The average age of patients was 40. I years. 2. The fractures were classified according to Neers method. Nearly half (48.1%) of the cases were one-part fractures. Next, two-part fractures rated 42.3%, while three-part fractures, only one (l.9%). 3. Among the total 52 patients, 42 cases(80.8%) were treated conservatively and 10 were operated. We performed surgical operations in seven cases among 22 two-part fractures, aix were reduced with Kirschner wires and one treated with Kirschner wire and staple. The average age of these seven cases was 26. 6 years and the resulta were good except one. 4. The results of these patients were evaluated by the Neers criteria. Of 52 caaes, 40 had good results, five, fair, and the remaining seven poor results. Twenty-three cases (92%) in 25(100%) one-part fractures were good and 17 cases (77.3%) in 22 (100%) two-part fractures were also good. In three-part and four-part fractures the results were all poor.
