Proximal Humerus Fractures: Randomized Study Between Locking Nails and Locking Plates for Neer 2 and 3 Parts

N/ACompletedNCT01984112

University of Sao Paulo72 enrolled

Overview

The hypothesis of this study is to determine whether the technique of intramedullary locking nail presents clinical results comparable to the technique of locking plates, based on the Constant Score.

Inclusion Criteria: * Fracture with less than 21 days; * Fractures of the proximal humerus classified as 2 or 3 parts of Neer, with involvement of the humeral head and one of the tuberosities; * Fracture with unacceptable deviation for the non-surgical treatment, according to the criteria of Neer Neer: fractures with deviation greater than 45 ° or 1 cm for the fragment of the humeral head and fractures with a deviation of the tuberosity greater than 0.5 cm; * Closed fractures; Exclusion Criteria: * Characteristics of the fracture: * fracture between the greater tubercle and the smaller, independent of the deviation; * Isolated fracture of the greater or lesser tuberosity * 4-part fractures of Neer; * Fracture involving the articular surface of the humeral head; * Fracture-dislocation of the proximal humerus * Other criteria: * Neurological injuries in the affected limb; * previous surgery on the affected shoulder; * associated fractures in the affected limb; * pathologic fractures; * lesions of the rotator cuff tendons previously diagnosed; * Psychiatric illnesses or inability to understand preoperative questionnaires; * Active infection or previous infection on the shoulder;
