Fractures of the upper end of the humerus are common, they represent about 5% of all fractures, and their frequency of occurrence increases to more than 1 0% beyond 65 years where they are the third cause of osteoporotic fractures of members after the fractures of the upper end of the femur and wrist. Even today there is no consensus on an algorithm about the therapeutic management of these fractures which passes from simple immobilization with humeral arthroplasty, through numerous techniques of fixation. The many therapeutic options reflect the difficulties encountered. We studied the functional results in the short medium and long terms of a therapeutic means of these fractures, and this through a retrospective study of 20 cases of fractures of the upper end of the humerus treated by anatomical bone plate in the department of orthopedic surgery B3 CHU Hassan II of Fez between January 2010 and June 201 5 with a mean of 10 months. Radiography of the shoulder front and profile transthoracic was done in all patients and allowed us to diagnose and specify its type according to Neer’s histological classification. Under general anesthesia in a semi sitting position, on an ordinary table, all of our patients had a fixation with anatomical plate. The surgical approach used was the “deltoid pectoral”. The medium period of solidification was 53 days. The absolute medium was Constant’s score was 84,96%. There was 1 case of stiffness and 2 cases of incomplete solidification. There was also 1 case of screw penetration. Complications were also found in our series. We have recorded no cases of avascular necrosis of the head of the bone. In conclusion, we can say that the anatomical plate fixation is a good therapeutic alternative. Therefore, our results are very satisfactory and close to perfect.
