We treated displaced proximal third ofthe humerus fracture without complications by skeletal traction andafter reposition by plaster. Oblique and transverse middle third ofthe humerus fracture was treated by Caldwell plaster. Average age ofthe patients was 37 years. The mean follow-up was 2,7years. Method: We examine patientsaccording to the classification of Stewar and-Hundley. Results: In the patients with proximalthird of the humerus fracture were obtained 8 very good, 8 good, 2poor results. In the patients with middle third of the humerusfracture were obtained 8 very good, 8 good, 2 fair, 2 poor results. Complications were observed in 4 cases: 2 non- union, 2fracture-union with angle position. Conclusion: Weconclude the non-operative method is useful in this kind of humerusfractures.
