Rotonda GD, Guastafierro A, Viglione S, et al. - In this study, the intramedullary augmentation technique was applied to present the perioperative, early, and late complications of proximal humeral fractures. Researchers treated 142 displaced proximal humeral fractures in the same unit by the aforementioned technique between 2005 and 2017. They assessed perioperative, early, and late complications in all patients. They conducted clinical assessment according to the Constant and Disabilities of the Arm, Shoulder and Hand scores. Intraoperative and postoperative analyses with short-, medium-, and long-term outcomes reveal that in complex and unstable cases, the intramedullary augmentation technique improves fracture treatment with significantly good anatomic reconstruction. The study found high bone healing rate, and the technique is correlated with a significantly low percentage of complications.
