Material and Methods

Thirty two patients with displced proximal humerus fracture were operated on between January 2002 and August 2007. After radiographic analysis, the fractures were classified into two types: non-compressive (without loss of bone tissue – not impacted fracture) and compressive (with permanent bone loss due to compression between the fragments – impacted valgus fracture) fractures. Depending on the presence or not of bone compression, two different plates were applied for osteosynthesis: a locking angled blade plate, for “non-compressive fractures” and a locking angled “spacer” plate, for “compressive fractures”.
