The plate fixation strategy of complex proximal humeral fractures.

PURPOSE For complex proximal humeral fractures, severe displacement and comminuted fragments lead to poor clinical outcomes. Despite considerable management, the locking plate fixation is still a preference and the proper selection of its strategy for each individual seems to be essential. METHOD The available classification system of the fracture, determination of surgical intervention, the common complications and related causes, and the latest critical surgical strategies with locking plate fixation were discussed in this review. RESULTS The frequent complications with complex proximal humeral fractures after operative treatment present a great challenge to orthopedic surgeons. In order to maintain the stability of locking plate fixation, several options including calcar screw, bone graft, bone cement augmentation, dual plate fixation, and fracture impaction were available for restoration of medial support. CONCLUSION Restoration of medial support seems of importance to provide solid stability and reduced complication for the complex fractures with fixation of locking plates.
