The operative treatment of comminuted and displaced fractures of the proximal humerus has been evolving in recent years. Classical open reduction and internal fixation techniques have an increased risk of avascular necrosis. Minimal osteosynthesis procedures often result in a suboptimal fracture reduction and require postoperative immobilization of the arm in some cases. ⋯ Plate fixation is an adequate procedure for treating unstable and displaced two- to four-part fractures of the proximal humerus. The incidence of avascular necrosis and non-union are low, when fracture reduction is performed indirectly. Plate fixation enables an early functional treatment, with no need for postoperative immobilization.

An autoimmunological approach to the pathogenesis of post-pericardiotomy syndrome. ⋯ In this study, we found a positive correlation between the presence of CMA and PPS, which is a practical, secure and cheap criterion for the diagnosis.
