Using a dynamic biomechanical model of malunion of the shoulder, we have determined the change in deltoid force required for abduction with various combinations of superior and posterior displacement of fractures of the greater tuberosity of the humerus. We tested eight fresh human cadaver shoulders in a dynamic shoulder-testing apparatus during cycles of glenohumeral abduction from 0 degrees t...

Background: The distal 1/3rd shaft tibia extra-articular fractures are treated with both tip locking intra-medullary nailing (TLIMN) and precontoured anatomical plates (PCALP). aim of this study was to compare the results TLIMN PCALP in determine dominant strategies. complications functional outcome groups were compared. Methods: Forty patients randomly assigned (group 1) group 2). outcomes eva...
