Clinical and radiographic outcome of open reduction and internal fixation of 3- and 4-part proximal humerus fractures augmented with impaction bone grafting and a magnesium-based bone filler

Augmentation of 3- and 4-part proximal humeral fractures with a standardized protocol utilizing cancellous chips and a synthetic magnesium-based bone filler results in a high rate of maintenance of fracture reduction, radiographic healing, and satisfactory patient outcomes. Further comparative data is needed to evaluate the efficacy of this technique compared to alternative methods of augmentation.
